In the February issue, we thoroughly tested a new video card from AMD , Radeon HD 6970 , and came to a disappointing conclusion that compared to a much cheaper Radeon HD 5870 it is a little faster in DX11-applications, but nothing more. Another creation of the company https://galaxy-spins-casino.co.uk/, released on the same day, has reached our laboratory only now. What will please Radeon HD 6950 , The younger sister of the one -chip flagship of the company?
Minimum changes
The AMD engineers decided to restrain the potential of the Radeon HD 6950 as a verified way: turning off the part of the functional blocks of the graphic nucleus and a decrease in operating frequencies. From 24 SIMD nuclear was cut off two, so that the chip lost 128 stream processors and 8 texture blocks. However, the remaining arsenal is still impressive: the video card has 1408 stream processors and 88 ROP – this should be enough for any modern game. They did not cut the memory subsystem: the tire of the device is still 256-bit, and the volume of the broken GDDR5 is 2 GB. The chips themselves, however, are used less high -quality, so their operating frequency is 5,000 MHz against 5500 MHz in the older model. Note that many manufacturers have already announced the reduced versions of Radeon HD 6950 with 1 GB of memory.
Usually AMD gives video cards based on one chip with different design, however, in the case of HD 6950/6970, this is not the case. Externally adapters are absolutely identical – one length, one design of the casing of the cooling system. The only difference lies in the power connectors: the youngest fee is content with two 6-Pin PCIE, since its maximum energy consumption does not exceed 200 watts, but HD 6970 with its TPD 250 watts is equipped with 6-pin and 8-pin connectors. As practice shows, it was not necessary to make this distinction: HD 6950 boards, turned into HD 6970 by rechargeing the BIOS, power is enough. Under the casing of the CO you can see a cooler already familiar to us based on the evaporative chamber. The design of the printed circuit board of both video cards is also identical.
In its own niche
Slides from the presentation of Radeon HD 6950 say that this adapter should create its own niche on the market and compete with any graphics card directly in its duties is not included. In essence, it is: the recommended price of the new item is $ 280, and in this segment today there are no other relevant solutions.
For comparison with our ASUS EAH 6950 We took four video cards – Radeon HD 6970 , HD 6870 , HD 5870 And GeForce GTX 470. The first two models are the neighbors of the test board in the AMD hierarchical staircase. The old HD 5870 was on the list due to a comparable retail price. Well, the GeForce GTX 470 is the NVIDIA board, the closest in price to HD 6950 (though the difference is still very large).
What in the end? The newcomer's lag from Radeon HD 6970 fluctuates in the range from 5 to 12 percent depending on the test. With a big difference in price, this result HD 6950 can be considered excellent. The separation of the Radeon HD 6950 from the recent HD 6870 is all the same 5-12 percent in the DX10- Benchmarks, but with rendering under DirectX 11, the fresh Radeon HD 6950 copes much better-thanks to the brand new teseselia engines. But the Radeon HD 5870 is already outdated and the Radeon HD 6950 is inferior in tests. The representative of the green camp, the GeForce GTX 470, lost the HD 6950 in all tests, which was quite expected.
* * *
It can be stated that at AMD It turned out a really good video card with support for many new technologies, including the long -awaited tesselation. Radeon HD 6950 of the IT of your money, and if you are ready to spend about 10,000 rubles on a graphic fee, then the choice is obvious.
Pros:
- Significantly cheaper, but only slightly slower than Radeon HD 6970
- + Having flashed the BIOS, you can turn the fee into Radeon HD 6970
- There are reduced versions with 1 GB of memory
- Nvidia has no boards in this price range
Cons:
- the price is overstated due to the lack of competitors
