GeForce GTX 295 vs Radeon R9 M385X

Intro

The GeForce GTX 295 comes with a core clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 TAUs, and 28 ROPs.

Compare that to the Radeon R9 M385X, which features core speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 295 should in theory be quite a bit superior to the Radeon R9 M385X overall. (explain)

GeForce GTX 295 223776 MB/sec
Radeon R9 M385X 96000 MB/sec
Difference: 127776 (133%)

Texel Rate

The GeForce GTX 295 should be a lot (more or less 50%) more effective at texture filtering than the Radeon R9 M385X. (explain)

GeForce GTX 295 92160 Mtexels/sec
Radeon R9 M385X 61600 Mtexels/sec
Difference: 30560 (50%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 295 is superior to the Radeon R9 M385X, by far. (explain)

GeForce GTX 295 32256 Mpixels/sec
Radeon R9 M385X 17600 Mpixels/sec
Difference: 14656 (83%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
