Power & Temperatures

While entry-level video cards may not top the performance charts, their low transistor count and low power usage means that they do very well on our power and temperature charts. And by being passively cooled, they are winners by default for noise, as they don’t generate any noise to measure.

On paper these cards differ by around a few watts when it comes to idle power, but by the time you put them in our i7 test rig, those few watts melt away. The Radeon 5450, the Radeon 4550, and the GeForce 210 all idle at 121W on our test rig, tying with the GeForce GT 240 for the lowest idle power usage we’ve measured.

Under load this changes some. The 5450 offers the second-lowest load power usage that we’ve measured, coming in below things like the GT 220 and the 4550. It doesn’t quite best the GeForce 210 however, which we believe to be a combination of the 210’s smaller-yet GPU and differences to how NVIDIA and AMD go about throttling their cards when we’re running FurMark.

At any rate, the 5450 does particularly well against other AMD cards, not only beating the 4000-series, but coming in under the 5670 by a hefty 47W. The 5670 may be the better HTPC card from a deinterlacing standpoint right now, but you pay for it with power.

We should note that for our load temperature testing, we use a closed case with all of the fans active on our Thermaltake Spedo case. So the results here are from plenty of airflow being sent towards the first PCIe x16 slot. Since we’re looking at passive cards today, they’re much more affected by this than actively cooled cards are. In a case with little to no airflow, these passive cards would definitely get hotter.

For load temperatures, the 5450 is the coolest video card we have ever tested, taking the title by 4C over its nearest competitor, the GeForce 210. This is thanks in a large part to the use of a double-wide heatsink for better heat dissipation, and of course the low power consumption of the 5450 in the first place. This also gives us a chance to quantify the differences between the double-wide heatsink on the reference card and the single-wide heatsink on the Sapphire 5450; the smaller Sapphire heatsink is only 4C worse at 51C. The double-wide heatsink in this case looks to be overkill.

At idle things change some. Our coolest cards are the actively cooled cards, which have their own fans to keep them cool. The passively cooled cards on the other hand build up some additional heat, coming in at the mid-40s, similar to several of our mid-range cards.

Sorted by Efficiency

Just like with the Blu-ray playback, adding a graphics card means a higher idle and load power use. This naturally means its performance to power consumption factor is the lowest too, with its direct competitor, the Core i3-530, up ahead by a few orders of magnitude.

Conclusion

What the Radeon HD 5450 graphics card brings to the party depends on what you want it for. It doesn’t help general productivity — it might reduce the demand on the main memory by integrated graphics, but this, in our test, makes no difference to real world CPU performance. Essentially, it’s adding to the system cost when you don’t need it. Office PCs, for example, will find integrated graphics is more than capable for doing things that people in suits and offices do.

If you do dabble in gaming, for PCs plugged into TVs at a 720p HD resolution the Radeon HD 5450 offers a more impressive and fluid gaming experience than onboard graphics. That said, while it’s a step up, it’s not a huge climb up the ladder. £40 buys you a few more FPS but with a 3D image that still look incredibly basic — this has always been the case at this price though, so we still strongly recommend saving up a little longer — even just £20 more — for something much more capable, while on a budget.

The best part about the Radeon HD 5450 is its capacity as a feature leading HTPC device (despite the current issues with MPC:HC, and there’s plenty of other software out there). If you do invest a little cash in a 785G motherboard with low power Athlon CPU, it can then easily be upgraded with a small, low profile, passively cooled HD 5450 should you get serious with your Blu-ray watching at a later date. If you do get serious, then the Core i3-530 is the better choice straight out the box: it does everything the HD 5450 does, features wise, with the same overall system costs, but featuring a CPU and GPU in one chip means lower power usage. As it’s an Intel CPU, it also offers better 2D performance in general.

Given the comparative cost of a stand alone Blu-ray drives, the PS3 factor, or one of the many bespoke h.264 HD-capable media players out there available for a fraction of the price — we fell that we may be looking at the last gasp area of the HTPC, an opinion the HD 5450 does nothing to change.

The Radeon HD 5450 directly challenges Intel’s GMA HD in the HTPC realm and certainly exceeds it for gaming, but in other areas — total system price, power usage — it’s outmoded. Still, AMD’s 890GX IGP is out in less than a month, so there remain plenty of interesting developments to come from the red team.

Today we present to your attention a review of the youngest video card among Radeons of the fifth series. This accelerator, based on the Cedar graphics processor, closes the series of ATI premieres as part of the launch of a new generation of video cards (not counting the other Radeon HD 5830 announced later). The release of the entry-level video card was planned even before the premiere of the HD 5870 and took place right on schedule — in the first quarter of this year.

The video card complies with both key features of the «5000th» family — the processor is manufactured in compliance with the 40-nm process technology and supports the DirectX11 API. However, you should not delude yourself — despite the use of advanced technologies, the accelerator that opens the lineup cannot be too powerful by definition. Among the people, such video cards are often disparagingly referred to as «gags», indicating an extremely low level of performance, insufficient even for «light» games. Often, such accelerators are delivered directly to the OEM market and find shelter in ready-made system units of the “advanced office” or “family computer” level. And yet, and it’s impossible not to write about it, dishonest sellers simply adore such cards, offering inexperienced users “gaming” configurations with completely inappropriate filling. Just imagine how good it sounds: «A powerful home computer with the latest ATI graphics card equipped with 512 MB of video memory and supporting DirectX11» 😉

In our testing, we’ll try to find out whether the new ATI accelerator can be used for its intended purpose, or whether the video card’s power is enough only to demonstrate the «desktop» and office work.

Those who wish can study the architecture of the new video processor in detail on the ATI presentation slide, which we present below:

The graphics core has 80 stream processors, 4 ROPs and 4 texture units. Thus, the new 40-nm Cedar graphics processor, in terms of the number and type of functional blocks, completely repeats the 55-nm RV710 used on the Radeon HD 4350 and Radeon HD 4550 video cards. The table shows the characteristics of these video cards for comparison with the new product:

recommendations

So, upon careful examination of the data, it becomes clear that the new video card, in terms of performance, can only slightly outperform its predecessors. The main advantages of the HD 5450 are explained by the transfer of the video processor to the 40-nm process technology: the video card consumes less power and has a slightly higher core frequency. Otherwise, the HD 5450 in the version with DDR2 video memory practically repeats the characteristics of the HD 4350, and with the GDDR3 video memory, the characteristics of the HD 4550. Interestingly, this fact can be seen in the new index: «450» ​​- just between «350 and «550», which means that the new video card is replacing both of these models. The next oldest model in the hierarchy of the «fifth series» — HD 5570 — is already a much more powerful accelerator based on the Redwood video processor.

It should be noted that «pure» power cannot be considered a priority characteristic of video cards of this class. This is also indicated by the content of ATI’s presentation dedicated to bringing the HD 5450 to the market. Very little attention is paid to the performance of the novelty here, but marketers are doing their best to focus on DirectX11 support and ATI Eyefinity technology. Regarding the first, let me immediately express my skepticism — what kind of use of DX11 can we talk about with such a meager processing power of the video card? According to this parameter, the HD 5450 is more than five times inferior to the already low-power HD 5670, or, for example, approximately fifty (!) Times to the current «world leader» in 3D graphics — Radeon HD 5970. So we can’t count on using DirectX11 to improve the picture, we just don’t have enough hardware resources on the HD 5450 to get decent graphics.

But another use of the new API — improving performance in «fresh» games (as a result of optimization) compared to the DirectX10 API, may be in demand. But even here everything is limited by the low power of the HD 5450. Looking ahead, let’s explain: for example, in the game «Stalker: Call of Pripyat» the inclusion of Dx11 (without tessellation and other «improvements») leads to an increase in performance compared to the Dx10-Dx10.1 modes — but we still cannot use this “bonus”, the framerate remains too low even at the minimum settings. In order to play Stalker, you need to switch the renderer to DX9 modeonly then will it be possible to obtain an acceptable number of frames per second. Similar situations can be repeated in other games where the new product will not have enough power.

Another innovation is support for ATI Eyefinity technology, which allows connecting several monitors to one video card, on the contrary, the HD 5450 is the strongest trump card. desktop space. Essentially, buying a younger Radeon now looks like the easiest and most affordable way to put together a three-monitor configuration.

Also worth mentioning is the ability of the “younger” Radeon to provide hardware acceleration and all sorts of additional picture improvements when playing high-definition video (VC-1 and H.264 formats). Considering the presence of an HDMI connector (revision 1.3a) and the ability of the board to also provide 7.1-channel audio output (192 kHz / 24-bit with support for various standards, up to DTS-HD audio and Dolby True HD), the video card looks like an excellent candidate for using as part of the multimedia center.
