Radeon HD 7750 vs Radeon R7 250
Intro
The Radeon HD 7750 uses a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this specific card. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.Compare that to the Radeon R7 250, which comes with GPU clock speed of 1000 MHz, and 1024 MB of GDDR5 memory set to run at 1150 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video 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 maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to 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.
