GeForce 8800 Ultra vs Radeon R5 M230

Intro

Compare those specs to the Radeon R5 M230, which makes use of a 28 nm design. AMD has set the core speed at 780 MHz. The DDR3 RAM runs at a speed of 1000 MHz on this particular card. It features 320 SPUs as well as 20 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8800 Ultra, in theory, should be quite a bit faster than the Radeon R5 M230 overall. (explain)

GeForce 8800 Ultra		103680 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 87680 (548%)

Texel Rate

The GeForce 8800 Ultra should be a lot (more or less 151%) better at texture filtering than the Radeon R5 M230. (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 23568 (151%)

Pixel Rate

The GeForce 8800 Ultra should be a lot (about 371%) faster with regards to full screen anti-aliasing than the Radeon R5 M230, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce 8800 Ultra		14688 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 11568 (371%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
