Just a quick word about the reference HD 7770. The Radeon HD 7770 is based on the Cape Verde (XT version) GPU. Cape verde is a 28nm GPU based on the GCN (Graphics Core Next) architecture. It features 640 SP (stream processors), 40 texture units and 16 color ROP units. From a GPU computing point of view, the Cape verde GPU has 10 compute units (64 SP per compute unit). The board embarks 1GB of GDDR5 graphics memory. The GPU is clocked at 1000MHz (the GHz edition!) while memory clock is 4500MHz effective or 1125MHz real speed.

ASUS HD 7770 DirectCU TOP comes with factory overclocked settings: 1120MHz for the GPU and 1150MHz real speed (4600MHz effective) for the memory.

The HD 7770 is a Direct3D 11.1 and OpenGL 4.2 capable graphics card. It also supports OpenCL 1.2 and DirectCompute 11.

The HD 7770 is refresh of previous generations: Radeon HD 6770 and Radeon HD 5770.

AMD Radeon R7 250X Reportedly a HD 7770 Rebrand

AMD is preparing their latest Radeon R7 250X for launch next month which would be placed directly against the GeForce GTX 750 series from NVIDIA which packs the Maxwell core. Reports from Fudzilla suggest that the R7 250X would be a HD 7770 rebrand.

AMD has quite a few sub-$100 SKUs which include the Radeon R7 250, Radeon R7 240 and the Radeon R5 230. The Radeon R7 250X would be the latest addition to this entry-level lineup packing the Cape Verde (Oland) core with 640 Stream processors, 40 TMUs and 16 ROPs. The clock speeds from an early listing of the Sapphire Radeon R7 250X which was leaked by Videocardz mentions a 1 GHz core and 4.5 GHz effective memory clock.

The card would be available in both 1 GB and 2 GB models and non-reference models would be available at launch so you’ll see each a diverse selection of R7 250X GPUs with their own set of coolers and designs from manufacturers. The Sapphire card in particular is just about the length of a PCI-e slot (a decent solution for a Steam Machine) and features a DVI, HDMI and Display port. Power is provided through a single 6-Pin power connector.

The card looks really interesting from the specifications which are a leap over the Oland based R7 250 and R7 240 but the extra performance results in higher power consumption so the card will feature a 6-Pin connector which compared to its Maxwell based GTX 750 counterpart is a downside. Maxwell is an extremely efficient design as being noted by the entry-level parts which are based on 28nm process but offer better specifications compared to their predecessors with a low power budget. AMD on the other hand is offering a rebranded HD 7770 to tackle the GeForce GTX 750 for $99 (same pricing as the GTX 750) which isn’t bad either. The new entry-level cards will end up putting a heated competition in this price range.

Video card review Sapphire HD 7770 Vapor-X GHz Edition OC

Regardless of the manufacturer, video cards based on the Radeon HD 7770 are currently one of the most interesting solutions. The cost of such devices is slightly higher than the psychological mark of $100, while these adapters have a very good price/performance ratio. nine0447 Sapphire HD 7770 Vapor-X GHz Edition OC is interesting, first of all, because in addition to increased frequencies, this model has at its disposal a cooling system with a vapor chamber.

020 Design and layout

The Vapor-X series graphics cards occupy a special place in Sapphire’s nomenclature. Traditionally, these are sufficiently productive solutions for which the use of CO with an integrated evaporation chamber is justified in terms of heat removal. Therefore, the appearance in the line of devices of a video card based on a very economical and relatively inexpensive Radeon HD 7770 aroused genuine interest.

Sapphire HD 7770 Vapor-X GHz Edition OC is based on the already well-known Cape Verde chip, which has a modern AMD Graphics Core Next graphics architecture and is produced using a 28-nanometer process technology. We will not dwell on the features of the GPU, those who wish can familiarize themselves with them in the corresponding material, but we will take a closer look at the capabilities of the video card from Sapphire. nine0003

The abbreviation OC in the model name does not ambiguously indicate factory tuning. So, the core operates at 1100 MHz (+10%), instead of the recommended 1000 MHz, and 1 GB of GDDR5 memory operates at 5200 MHz (+16%), while for reference models the standard is 4500 MHz.

The proprietary cooling system is based on a vapor chamber that is in direct contact with the GPU. The main radiator block is a set of aluminum plates. The dimensions and, accordingly, the dissipation area of the latter are relatively small, but in this case we are talking about a device with a declared TDP of 80–100 W, so there is no need to overdo it. nine0003

The design also uses two heat pipes, which are pressed into the base of the heat sink and diverge in opposite directions, penetrating the radiator cassette. A pair of 80 mm axial fans is used to blow the radiator. Their blades have a specific curved profile to increase airflow.

The top of the cooler is covered with a plastic casing with glossy and matte surfaces, which also contains a decorative insert made of transparent plexiglass. nine0003

The Sapphire HD 7770 Vapor-X GHz Edition OC uses a printed circuit board very similar to the reference one, but made on turquoise textolite. The subsystem of the converter is made according to the «3+1+1» scheme. The length of the PCB is 210 mm, but the protruding edges of the protective decorative cover of the cooler increase the dimensions of the video card to 225 mm. The device is quite compact, there will be no difficulties with installation in an average case.

Only the connector for the CrossFireX bridge is located on the top edge of the PCB, while the six-pin connector for connecting additional power is installed on the back side. nine0003

The interface panel has a classic layout and a set of connectors for video cards with two-slot COs — a pair of DVI, as well as full-format HDMI and DisplayPort. A quarter of the fixing plate is given to the ventilation grille.

Delivery set

The delivery set for devices of this level is rarely surprising. Manual, driver CD, Molex to 12B six-pin adapter, DVI to VGA adapter. A typical set for a video card in this price segment. nine0003

A nice bonus is the included 1.8 m HDMI cable.

In operation

In the minimum load mode, the graphics chip warms up to 32-33 degrees. At the same time, we note that the video card works very quietly. With a subjective assessment “by ear”, it seemed that the fans were already very low-speed, but upon visual inspection, as well as the actual rotation speeds, it turned out that this was not the case. Quite standard for such conditions ~ 1200 rpm. The successful design of the impeller and good balancing do their job. nine0003

Under a serious game load, the GPU warmed up to 62 C on an open bench, and, curiously, the level of noise emitted practically did not increase. It is not surprising, since the rotational speed in this case increased only to ~1350 rpm. In this case, it is obvious that the design of the evaporative chamber cooler with heat pipes does a good job of dissipating heat, so there is no need to spin the fans in vain.

Continuing to investigate the efficiency of the cooler, higher temperatures were achieved only after the launch of FurMark. Synthetic «donut», once again confirming the title of a fierce enemy of any video card, warmed up the chip to 67 degrees. Fan speed even in this case increased only to 1600 rpm. nine0003

Overclocking

Exploring the potential of the video card in forced mode, we managed to increase the GPU frequency to 1190 MHz , while the memory remained stable at 5980 MHz . For adapters based on Cape Verde chips, these are high figures, although not record-breaking.

Performance

Obviously, having increased clock speeds (1100/5200 MHz), the video card from Sapphire will have a certain advantage over the Radepn HD 7770 with the recommended formula (1000/4500 MHz). nine0003

In normal mode, the advantage of Sapphire HD 7770 Vapor-X GHz Edition over the reference Radeon HD 7770 is ~ 7-15%, while after additional overclocking it increases to more significant 17-25%. In the confrontation with a video card based on the Barts chip, a lot depends on the specific optimization of the engine. More often than not, the advantage is on the side of the overclocked video card on Cape Verde, but in a number of disciplines the Radeon HD 6850 reminds us that it is too early to write it off. nine0003

Results

Based on the combination of characteristics Sapphire HD 7770 Vapor-X GHz Edition OC deserves high marks. Initially, noticeably increased clock speeds enable it to compete on equal terms in terms of performance, and often even surpass the Radeon HD 6850. The cooling system should be especially noted. The proprietary development of the Vapor-X with a vapor chamber in this case proved to be the best — and it works very quietly, and does its main task perfectly. The reviewed modification of the video card from Sapphire costs $10-15 more than models with recommended frequencies and cooling systems close to the reference one. In our opinion, given these advantages, such an overpayment is justified.
