VS

GeForce 8300 GS (OEM) vs Radeon R5 M255

Intro

The GeForce 8300 GS (OEM) features a core clock speed of 450 MHz and a DDR2 memory frequency of 400 MHz. It also features a 64-bit bus, and uses a 80 nm design. It features 8 SPUs, 4 TAUs, and 2 Raster Operation Units.

Compare all of that to the Radeon R5 M255, which comes with GPU clock speed of 940 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also is comprised of 320 Stream Processors, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R5 M255 should theoretically be quite a bit superior to the GeForce 8300 GS (OEM) in general. (explain)

Radeon R5 M255 16000 MB/sec
GeForce 8300 GS (OEM) 6400 MB/sec
Difference: 9600 (150%)

Texel Rate

The Radeon R5 M255 should be much (about 944%) more effective at anisotropic filtering than the GeForce 8300 GS (OEM). (explain)

Radeon R5 M255 18800 Mtexels/sec
GeForce 8300 GS (OEM) 1800 Mtexels/sec
Difference: 17000 (944%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R5 M255 is superior to the GeForce 8300 GS (OEM), and very much so. (explain)

Radeon R5 M255 7520 Mpixels/sec
GeForce 8300 GS (OEM) 900 Mpixels/sec
Difference: 6620 (736%)

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 information (in units of MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high 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 texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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 max fill rate.
