GeForce GT 1030 vs Radeon HD 4850 X2 1GB

Intro

The GeForce GT 1030 features a core clock frequency of 1265 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 64-bit memory bus, and uses a 16 nm design. It is comprised of 384 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare all that to the Radeon HD 4850 X2 1GB, which features a GPU core clock speed of 625 MHz, and 1024 MB of GDDR3 memory running at 993 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030 30 Watts
Radeon HD 4850 X2 1GB 250 Watts
Difference: 220 Watts (733%)

Memory Bandwidth

In theory, the Radeon HD 4850 X2 1GB will be 159% quicker than the GeForce GT 1030 in general, because of its higher bandwidth. (explain)

Radeon HD 4850 X2 1GB 127104 MB/sec
GeForce GT 1030 49152 MB/sec
Difference: 77952 (159%)

Texel Rate

The Radeon HD 4850 X2 1GB is quite a bit (about 24%) faster with regards to anisotropic filtering than the GeForce GT 1030. (explain)

Radeon HD 4850 X2 1GB 50000 Mtexels/sec
GeForce GT 1030 40480 Mtexels/sec
Difference: 9520 (24%)

Pixel Rate

The GeForce GT 1030 will be just a bit (about 1%) more effective at anti-aliasing than the Radeon HD 4850 X2 1GB, and also will be able to handle higher screen resolutions better. (explain)

GeForce GT 1030 20240 Mpixels/sec
Radeon HD 4850 X2 1GB 20000 Mpixels/sec
Difference: 240 (1%)

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: Bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
