GeForce GT 220 GDDR3 vs Radeon VII

Intro

Compare all that to the Radeon VII, which makes use of a 7 nm design. AMD has set the core speed at 1400 MHz. The HBM2 memory runs at a frequency of 1000 MHz on this specific model. It features 3840 SPUs as well as 240 TAUs and 64 Rasterization Operator Units.

Power Consumption (Max TDP)

GeForce GT 220 GDDR3		58 Watts
Radeon VII		295 Watts
	Difference: 237 Watts (409%)

Memory Bandwidth

As far as performance goes, the Radeon VII should theoretically be a lot better than the GeForce GT 220 GDDR3 in general. (explain)

Radeon VII		1048576 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 1016192 (3138%)

Texel Rate

The Radeon VII should be quite a bit (more or less 3260%) faster with regards to texture filtering than the GeForce GT 220 GDDR3. (explain)

Radeon VII		336000 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 326000 (3260%)

Pixel Rate

The Radeon VII should be a lot (about 1692%) more effective at FSAA than the GeForce GT 220 GDDR3, and capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon VII		89600 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 84600 (1692%)

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 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 interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better 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 most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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 memory bandwidth is, the lower the potential to get to the max fill rate.
