Compare any two graphics cards:
Radeon HD 7990 vs Radeon R9 295X2
IntroThe Radeon HD 7990 features a core clock frequency of 950 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It features 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.Compare that to the Radeon R9 295X2, which features core clock speeds of 1018 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 RAM. It features 2816 SPUs along with 176 Texture Address Units and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 295X2 should in theory be a bit better than the Radeon HD 7990 in general. (explain)
Texel RateThe Radeon R9 295X2 should be much (approximately 47%) better at anisotropic filtering than the Radeon HD 7990. (explain)
Pixel RateThe Radeon R9 295X2 will be quite a bit (approximately 114%) better at full screen anti-aliasing than the Radeon HD 7990, and also will be able to handle higher screen resolutions while still performing well. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

7 Responses to “Radeon HD 7990 vs Radeon R9 295X2”7990 is no longer the king.
R9 295 X2 FTW.
Der König ist tot, lang lebe der König( ~6-12 monate)
the R9 295X2 has 4096MB ram x2, not 80192!
amd R9 295X2 can win NVIDIA GEFORCE TITAN Z!
The 7990 had a good run
Remember, the R9 295x2 is a dual core gpu. The hd 7990 has a higher performance technically because it has a better single gpu
