GeForce GT 1030 vs Radeon HD 3850 256MB

Intro

The GeForce GT 1030 uses a 16 nm design. nVidia has set the core frequency at 1265 MHz. The GDDR5 memory runs at a speed of 1502 MHz on this particular card. It features 384 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon HD 3850 256MB, which comes with core speeds of 668 MHz on the GPU, and 828 MHz on the 256 MB of GDDR3 memory. It features 320(64x5) SPUs along with 16 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030 30 Watts
Radeon HD 3850 256MB 75 Watts
Difference: 45 Watts (150%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 3850 256MB should be 8% faster than the GeForce GT 1030 overall, because of its higher data rate. (explain)

Radeon HD 3850 256MB 52992 MB/sec
GeForce GT 1030 49152 MB/sec
Difference: 3840 (8%)

Texel Rate

The GeForce GT 1030 should be quite a bit (more or less 279%) more effective at anisotropic filtering than the Radeon HD 3850 256MB. (explain)

GeForce GT 1030 40480 Mtexels/sec
Radeon HD 3850 256MB 10688 Mtexels/sec
Difference: 29792 (279%)

Pixel Rate

The GeForce GT 1030 is quite a bit (about 89%) faster with regards to AA than the Radeon HD 3850 256MB, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GT 1030 20240 Mpixels/sec
Radeon HD 3850 256MB 10688 Mpixels/sec
Difference: 9552 (89%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core 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 maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
