Is the Sapphire HD 7950 double dissipation overclock edition?

The XFX R7950 Black Edition Double Dissipation and Sapphire HD 7950 Overclock Edition are far more representative of what we’re actually going to see on the market; factory overclocks aside, both use open air coolers, just as with every other 7950 card we’ve seen the specs for ahead of today’s launch.

How many shaders does the AMD Radeon HD 7950 boost have?

Unlike the fully unlocked Radeon HD 7970, which uses the same GPU but has all 2048 shaders enabled, AMD has disabled some shading units on the Radeon HD 7950 Boost to reach the product’s target shader count. It features 1792 shading units, 112 texture mapping units, and 32 ROPs.

Which is better AMD Radeon HD 7950 or sapphire toxic R9 280x?

The TOXIC R9 280X 3GB GDDR5 (UEFI) has more TMUs, which stands for Texture Mapping Units, and higher graphics frequency, therefore its texture fillrate is substantially higher.

Is the Radeon HD 7950 based on Tahiti silicon?

This is what makes it an important model for AMD. The Radeon HD 7950 is carved out of the 28 nm “Tahiti” silicon, on which the HD 7970 is based.

What’s the difference between AMD Radeon HD 7970 and 7950?

Today AMD is launching the Radeon HD 7950, the cooler, quieter, and cheaper sibling of the Radeon HD 7970. Aimed right at NVIDIA’s GeForce GTX 580, AMD is looking to sew up the high-end market, and as we’ll see the Radeon HD 7950 is exactly the card to accomplish that.

Is the AMD Radeon HD 7950 a Tahiti card?

The second Tahiti card has been waiting in the wings for its own launch, and that launch has finally come. Today AMD is launching the Radeon HD 7950, the cooler, quieter, and cheaper sibling of the Radeon HD 7970.

Why was the shader count reduced on the AMD HD 7950?

The second change is that the shader count has been reduced from a full 2048 SPs to 1792 SPs, accomplished by disabling 1 of the GPU’s 8 CU arrays and allowing AMD to use Tahiti GPUs with a defective CU array that would have never worked in the first place.
