Radeon HD 7750 vs Radeon R7 250
Intro
The Radeon HD 7750 makes use of a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this specific card. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon R7 250, which has core clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must 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, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.

3 Responses to “Radeon HD 7750 vs Radeon R7 250”R7 250 sucks. 7750 wins.....
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
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.
