GeForce GTX 1630 vs Radeon HD 4850 X2 512MB

Intro

The GeForce GTX 1630 features a core clock frequency of 1740 MHz and a GDDR6 memory frequency of 1500 MHz. It also features a 64-bit memory bus, and uses a 12 nm design. It is comprised of 512 SPUs, 32 TAUs, and 16 ROPs.

Compare those specifications to the Radeon HD 4850 X2 512MB, which features GPU clock speed of 625 MHz, and 512 MB of GDDR3 RAM set to run at 993 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630 75 Watts
Radeon HD 4850 X2 512MB 250 Watts
Difference: 175 Watts (233%)

Memory Bandwidth

In theory, the Radeon HD 4850 X2 512MB should be much faster than the GeForce GTX 1630 in general. (explain)

Radeon HD 4850 X2 512MB 127104 MB/sec
GeForce GTX 1630 98304 MB/sec
Difference: 28800 (29%)

Texel Rate

The GeForce GTX 1630 should be a little bit (more or less 11%) faster with regards to AF than the Radeon HD 4850 X2 512MB. (explain)

GeForce GTX 1630 55680 Mtexels/sec
Radeon HD 4850 X2 512MB 50000 Mtexels/sec
Difference: 5680 (11%)

Pixel Rate

The GeForce GTX 1630 should be a lot (about 39%) more effective at full screen anti-aliasing than the Radeon HD 4850 X2 512MB, and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 1630 27840 Mpixels/sec
Radeon HD 4850 X2 512MB 20000 Mpixels/sec
Difference: 7840 (39%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses 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, 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 number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
