Radeon HD 7750 vs Radeon R7 250

Intro

The Radeon HD 7750 uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this particular card. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon R7 250, which comes with GPU clock speed of 1000 MHz, and 1024 MB of GDDR5 RAM set to run at 1150 MHz through a 128-bit bus. It also is comprised of 384 SPUs, 24 TAUs, and 8 ROPs.

Radeon R7 250 73600 MB/sec
Radeon HD 7750 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon HD 7750 will be a bit (more or less 7%) more effective at AF than the Radeon R7 250. (explain)

Radeon HD 7750 25600 Mtexels/sec
Radeon R7 250 24000 Mtexels/sec
Difference: 1600 (7%)

Pixel Rate

The Radeon HD 7750 should be much (approximately 60%) better at AA than the Radeon R7 250, and also should be able to handle higher resolutions more effectively. (explain)

Radeon HD 7750 12800 Mpixels/sec
Radeon R7 250 8000 Mpixels/sec
Difference: 4800 (60%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

R7 250 sucks. 7750 wins.....
harry says:
hd 7750 is best gpu in under 10 k

and its really souport dx 11.1

and gives u ultimate 30-45 fps on all letest games with on screen 3d view and

all of us vicely know
amd gameing view is much better than nvidia

Tom says:
R7 250 used to play dx12 games. And better bandwidth. Easily Play next gem games in medium settings. I think R7 250 is a step ahead for the future vision.
