GeForce GT 310 vs Radeon HD 6450 (OEM)

Intro

Compare those specifications to the Radeon HD 6450 (OEM), which comes with core speeds of 625 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 RAM. It features 160 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GT 310 should in theory be a lot faster than the Radeon HD 6450 (OEM) overall. (explain)

GeForce GT 310		16000 MB/sec
Radeon HD 6450 (OEM)		12800 MB/sec
	Difference: 3200 (25%)

Texel Rate

The Radeon HD 6450 (OEM) should be just a bit (about 6%) faster with regards to AF than the GeForce GT 310. (explain)

Radeon HD 6450 (OEM)		5000 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 288 (6%)

Pixel Rate

The Radeon HD 6450 (OEM) should be a bit (about 6%) better at AA than the GeForce GT 310, and also should be capable of handling higher resolutions better. (explain)

Radeon HD 6450 (OEM)		2500 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 144 (6%)

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 maximum amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
