GeForce GTX 465 vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which makes use of a 28 nm design. AMD has clocked the core frequency at 1030 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this model. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 465 should theoretically perform much faster than the Radeon R5 M330 overall. (explain)

GeForce GTX 465		102592 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 88192 (612%)

Texel Rate

The GeForce GTX 465 will be quite a bit (about 30%) better at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 6108 (30%)

Pixel Rate

The GeForce GTX 465 will be a lot (more or less 136%) better at FSAA than the Radeon R5 M330, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 11184 (136%)

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 maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
