GeForce RTX 3060 vs Radeon HD 7770

Intro

Compare those specifications to the Radeon HD 7770, which has clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

	Difference: 90 Watts (113%)

Memory Bandwidth

In theory, the GeForce RTX 3060 is 412% quicker than the Radeon HD 7770 in general, because of its greater bandwidth. (explain)

GeForce RTX 3060		368640 MB/sec
Radeon HD 7770		72000 MB/sec
	Difference: 296640 (412%)

Texel Rate

The GeForce RTX 3060 should be a lot (about 270%) more effective at anisotropic filtering than the Radeon HD 7770. (explain)

GeForce RTX 3060		147840 Mtexels/sec
Radeon HD 7770		40000 Mtexels/sec
	Difference: 107840 (270%)

Pixel Rate

The GeForce RTX 3060 will be quite a bit (approximately 296%) more effective at anti-aliasing than the Radeon HD 7770, and capable of handling higher screen resolutions better. (explain)

GeForce RTX 3060		63360 Mpixels/sec
Radeon HD 7770		16000 Mpixels/sec
	Difference: 47360 (296%)

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 max amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 maximum fill rate.
