AMD A6-7400K processor review and testing GECID.com. Page 1 ::>Processors 12-17-2014 Page 1 AMD’s updated line of APUs, codenamed «Kaveri», brings a number of new technologies to the series, as well as lower overall power consumption and improved performance. In previous articles, we have already got acquainted with high-performance solutions of this series: AMD A10-7850K, AMD A10-7800 and AMD A10-7700K. This material will be devoted to a more affordable APU. Model AMD A6-7400K is equipped with two compute cores and AMD Radeon R5 series graphics. If you look only at the cost of this novelty, then in this parameter it is a competitor to the Intel Pentium series processors. Specification:
Packaging, delivery and appearance The processor comes in a colorful package that features AMD’s signature colors of red and black. On the front side there is a stylized image of the APU, and the presence of an integrated graphics core is also noted. The side face traditionally contains a small transparent window that allows you to get acquainted with the appearance of the device, as well as study its marking and country of manufacture. AMD A6-7400K includes:
In addition to the marking, the AMD A6-7400K cover shows the country where the crystal was grown (Germany) and where the final assembly was carried out (Malaysia). Long copper pins are used, which are quite fragile, so you need to be very careful when installing the processor into the socket. Standard cooling system The new product comes with a fairly simple cooling system, which consists of a small aluminum radiator and a fan with the designation «FHSA7015S» with a diameter of 70 mm. This cooler is based on a hydraulic bearing, and its maximum rotation speed can reach 2800 rpm. The manufacturer also declared the maximum noise level, which should not exceed 20 dB. The fan is connected using a standard four-pin connector, which allows you to control its speed using the PWM method. The heatsink contacts the processor thermal cover through a thin layer of thermal paste. To fix the entire CO, a standard metal mount with plastic latches is used, which has proven to be reliable, since it is used in most AMD processors. Complete cooling systems for AMD A6-7400K (left) and AMD FX-8320E (right) processors In our opinion, the comparison of standard cooling systems for AMD A6-7400K and AMD FX-8320E processors looks quite interesting. As you can see, the cooler used in the tested novelty has a noticeably smaller heatsink and a redesigned fan blades. At the same time, its TDP is also significantly lower: 65 W versus 95 W. Performance Analysis Together with the AMD Kaveri line, AMD switched to the designation of computing cores in APUs instead of processor and graphics. This approach is quite logical, given the peculiarities of the microarchitecture, but we will use a more familiar one. So, AMD A6-7400K has two processor cores that work in dual-threaded mode. Its nominal frequency (at the time of reading) was at the level of 3493 MHz with a multiplier of «x35» and a reference frequency of 100 MHz. At the same time, the core voltage was at around 1. After activating AMD Turbo Core 3.0 technology, the multiplier value rose to «x39», which led to an increase in the clock frequency to 3900 MHz. The voltage on the core during readings was at the level of 1.360 V. When using the bench cooling system, the temperature of the novelty did not exceed 37°C, which is a very good result and significantly expands the list of COs that can be used with this processor. AMD A6-7400K went into idle mode under light load. In this state, its clock frequency did not exceed 1400 MHz (with a multiplier of «x14»), and the voltage was at a very low level — 0.592 V. The cache memory distribution of the hero of this review is as follows. 16 KB of L1 cache per core with 4 associativity channels is allocated for data caching. Instructions are allocated 96 KB of shared L1 cache with 3 associativity channels. Additionally, 1024 KB L2 cache with 16 associativity channels is provided. The integrated memory controller supports dual-channel operation of DDR3 modules with an effective frequency of up to 1866 MHz. The AMD A6-7400K processor is equipped with a sufficiently powerful integrated graphics core of the AMD Radeon R5 Graphics series. It consists of 256 universal shader processors, 16 texture units and 4 raster units. At maximum load, the graphics processor operates at a frequency of 758 MHz.

AMD
Description AMD started AMD A6-7400K sales 31 July 2014. This is Kaveri architecture desktop processor primarily aimed at office systems. It has 2 cores and 2 threads and is manufactured in 28nm process technology, the maximum frequency is 3900 MHz, multiplier locked. In terms of compatibility, this is an FM2+ socket processor with a TDP of 65W and a maximum temperature of 72°C. It supports DDR3-1866 memory. It provides poor benchmark performance at 1.58% from the leader, which is AMD EPYC 7h22. or General informationInformation about the type (desktop or laptop) and architecture of the A6-7400K, as well as when sales started and cost at that time.
CompatibleInformation on A6-7400K compatibility with other computer components. Useful, for example, when choosing the configuration of a future computer or to upgrade an existing one. Please note that the power consumption of some processors can significantly exceed their nominal TDP even without overclocking. Some may even double their claims if the motherboard allows you to adjust the power settings of the processor.
Virtualization Technologies
Technologies supported by A6-7400K that speed up virtual machines are listed.
For comparison, we will take four older processors (including one very old) from three, again, families. An important fact — without loud statements, the company actually «increased the value» of the graphics part of each family: the number of GPUs in modern A6 is the same as in the old A8, and in A8 there are as many as there were in A10. This is not to mention the architecture update — GCN instead of VLIW4. Most of the new A10s (with the exception of the 7700K, which belongs to the A10 family without any reason) are even higher. Considering that the bottleneck in older models is the memory system, it may turn out that such a GPU boost is simply superfluous. This, among other things, we will check. And let’s also check how much Kaveri needs “enhanced power supply”, since all three models we have taken support Custom TDP. The fact that performance decreases when the heat pack is limited is a fact that has been repeatedly verified, but it is interesting how it compares with the old “gluttonous” models. Test methodologyTo evaluate performance, we used our performance measurement methodology using iXBT Notebook Benchmark v.1.0 and iXBT Game Benchmark v.1.0. We normalized all test results in iXBT Notebook Benchmark v.1.0 relative to the results of Pentium G3250 with 8 GB of memory and Intel 520 240 GB SSD, while the method of calculating the integral result remained unchanged. Another program that we, like last time, added to the test suite is the Basemark CL 1.0.1.4 benchmark, created to measure the performance of OpenCL code. iXBT Notebook Benchmark v.1.0 A6 contains only one module, so this is a completely different world in terms of multi-threaded programs than A8 and A10, which (not surprisingly) differ from each other only in clock frequencies. Curiously, even in the 45 W mode, the models we have taken are already faster than any processors for FM1, and in the “regular” mode they are easily able to compete with APUs for FM2 with a TDP of 100 W. The difference between families remains, but between generations it decreases. But, in principle, as we can see, even 45 W is not such a terrible limitation: the performance remains at the level of the Pentium of the recent past. Not much of an achievement, as we’re comparing two- and four-threaded processors in applications that can use all the resources, but the «regular» Pentium models have a slightly larger thermal package. Well, if you don’t “clamp” it, then once again intra-company competition looks interesting — not every old model with a TDP of 100 W can overtake the new economical APUs of the A8 and A10 families in terms of performance. Photoshop, as we have already written more than once, is not too susceptible to the number of computation threads. But not completely immune — after all, the A6 (both new and old) is about one and a half times slower than two-module models of all generations. Audition needs more than two cores (and even semi-cores), to an even lesser extent than Photoshop, but this does not allow A6 (the best modifications) to keep up with processors of higher classes. On the other hand, the latter is far from the dual-core Pentium, and even Celeron based on modern architectures. Well, where there is multi-threaded optimization, A8/A10 keep quite at the Pentium level, and A6 lag behind all those listed by a couple of times. Nothing new. So, we can only once again pay attention to the increase in the energy efficiency of modern APUs, which, even with a limited heat pack, are able to fight on equal terms with the old top models. In WinRAR, all newfangled optimizations fail, so everything starts to be determined by the clock frequency, which is not high in Kaveri in all variants. A processor with a lower TDP leads to increased «viscosity» of the system, although, other things being equal, this is not very noticeable. If only because the A10-7800 in 45W mode keeps at the level of the first generation FM2 with a TDP of 100W. And the main thing in this test is not the processor at all — we recall that «hard» laptops in this test are on average three times slower, regardless of the central processor. In general, it’s worth starting anyway with the purchase of a solid-state drive (even when assembling a budget system), and then paying attention to other components. Why does the A10-7850K look pale compared to its predecessors? Why is the Steamroller microarchitecture used only in the APU, while the multi-module processors of the FX family remained on the older Piledriver? It seems to us that this diagram explains a lot. As for more mundane things, it is obvious that one module is not enough for many modern programs. Moreover, just in this configuration, there is no special gain from the new architecture: A6-6420K and A6-7400K come to the finish line head to head when using the same heat pack. OpenCL What distinguishes any APU of the Kaveri family from its predecessors is the performance when executing OpenCL code: even the A6-7400K in 45 W mode easily overtakes both the old A10 and Intel processors with HD Graphics 4600 GPU. As a result, we can only drag out the old song: now, if all this extended not only to synthetic benchmarks, but also to mass-purpose programs. Indeed: the new architecture of the graphics part would allow even lower-end models to easily catch up and overtake even expensive Core i7, clearly demonstrating the advantages of AMD’s approach to creating processors. But the reality so far looks much more boring and familiar. As expected based on the performance characteristics, the gaming performance of the new A6 is about the same as the old A8, and the latest generation A8 is able to compete with the A10. That’s what’s unpleasant — and with the new A10 too, since the limiting factor is the memory bandwidth, and it is already maximum in the Kaveri-based A8. In general, we are convinced that the A8 of the 7000 series is already enough to play this game in high resolution, and there is no point in paying for the A10 — it will not be faster. In this FullHD game, even the old A6 «pulls out», but only older models. At the same time, one module is already not enough, so the A8-7600 turns out to be the best option from the tested ones: more expensive models are not faster, and cheaper ones are much slower. It is noteworthy that despite the single-threaded «tank» engine, A6 noticeably loses here to any dual-module processors. Other than that, there is no alternative to the older Richland high-frequency ones (which we have long seen), although this is not so important — since the A8-7600 in FullHD even with a limited heat pack produces more than 50 frames per second. Quite easy for modern processors, the game well demonstrates different requirements for them depending on the mode — if in HD A10-6800K is out of competition, then in Full HD it lags behind A8-7600 by 65 W, and from A10- 7800 — even in the most economical mode. A6 «does not pull» this game in any mode, since one module is not enough for it even in terms of the processor part, but A8 and above is enough for at least HD. Moreover, in economy mode, but “and above” is not required. The situation is similar to the previous case, but here the requirements for the processor are even higher, and for graphics — perhaps lower, so on modern A8 and any A10 you can already try to use the full resolution of modern monitors. Total So, as mentioned above, the heat pack limit reduces the performance of the processor part in an acceptable way, and has almost no effect on games at all. In general, if we assume that energy efficiency was at the forefront when creating Kaveri, then this goal is more than achieved. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Lightning damaged him a little. A. 
5/3.9 
We have already tested the older processor in detail, but we did not communicate with the younger ones. It’s time to take care of them too. 
There are two A8, since there are two platforms — we are still interested to look again at the competition of four «half-cores» with four cores We had comparisons, so the old one is more interesting as a guide. 
Well, the A6 is twice as slow, and it doesn’t really matter if it’s new or old. 
But the lag behind the quad-core APUs for FM1 has been greatly reduced. And in general, the best model for this platform also lags behind the A8-7600 in 45 W mode, which is quite interesting for those who plan to assemble a computer in a compact case. 
On the other hand, the A10-7800 still looks good, but it is quite expensive, and the A8-7600 is already outperformed by its immediate predecessors. Or even not direct — 5600K is a two-year-old model. However, in fairness, if we took not it, but the 5500 with a TDP of 65 W, there would be no lag. but the win is still the same ? 
It’s very simple: Steamroller is not for maximum performance, it’s an example of good scaling «down». In fact, the third generation of APUs is intended primarily for laptops — AMD has done the same thing as Intel did earlier: the «desktop» market is no longer a locomotive, but something that turns out according to the residual principle. At the time of Llano, an attempt to limit the heat pack to the acceptable level in portable computers led to dramatic consequences: when the A8-3500M could not keep up with the budget desktop A6-3500 with fewer cores, and the Pentium G2130 lagged behind one and a half times. Because of which? Yes, just due to the need to meet 35 watts. Well, Kaveri in the 45 W mode at least calmly competes with the Pentium, and in general — doubling the heat pack allows you to increase performance by only 20%. Actually, do you need it? ? 
The addition of the second module changes the situation radically — the performance increases one and a half times, which is very good. And, as expected, there is no difference between the A8 and A10 in these tests — their processor component is almost the same. So it’s more interesting to look at the tests of the graphics core. 
And given that these APUs are primarily focused on the market of computers without discrete graphics (laptops, mini-PCs, inexpensive and compact multimedia system units), this situation generally causes a feeling of deep satisfaction ? As for achieving high performance, not everything is going smoothly here , since even two modules at full load are comparable only with Pentium, and at partial load they lag behind it. An attempt to increase the operating frequencies mainly leads to an increase in power consumption, not compensated by an increase in performance (it is, but obviously insufficient), and the limitations of the memory system make it pointless to increase the number of GPUs above a certain level, and the price of older models turns out to be too high to be achievable (taking into account the listed bottlenecks) by their performance. In a word, the best Kaveri models are A8, where “everything is already there”, but still “nothing interferes”, and the final price is at the level of that of Pentium with significantly better graphics.
