GeForce 9800 GT 1GB vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which comes with GPU clock speed of 1030 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9800 GT 1GB should in theory be quite a bit faster than the Radeon R5 M330 overall. (explain)

GeForce 9800 GT 1GB		57600 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 43200 (300%)

Texel Rate

The GeForce 9800 GT 1GB will be much (more or less 63%) more effective at AF than the Radeon R5 M330. (explain)

GeForce 9800 GT 1GB		33600 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 13000 (63%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 9800 GT 1GB is superior to the Radeon R5 M330, but only just. (explain)

GeForce 9800 GT 1GB		9600 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 1360 (17%)

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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
