GeForce GT 1030 vs GeForce GT 340 1GB

Intro

The GeForce GT 1030 makes use of a 16 nm design. nVidia has clocked the core speed at 1265 MHz. The GDDR5 memory runs at a speed of 1502 MHz on this particular model. It features 384 SPUs along with 32 TAUs and 16 ROPs.

Compare all of that to the GeForce GT 340 1GB, which features core speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 96 SPUs along with 32 TAUs and 8 ROPs.

GeForce GT 1030 49152 MB/sec
Difference: 5248 (11%)

Texel Rate

The GeForce GT 1030 will be quite a bit (about 130%) more effective at texture filtering than the GeForce GT 340 1GB. (explain)

GeForce GT 1030 40480 Mtexels/sec
GeForce GT 340 1GB 17600 Mtexels/sec
Difference: 22880 (130%)

Pixel Rate

The GeForce GT 1030 will be a lot (more or less 360%) more effective at AA than the GeForce GT 340 1GB, and capable of handling higher resolutions better. (explain)

GeForce GT 1030 20240 Mpixels/sec
GeForce GT 340 1GB 4400 Mpixels/sec
Difference: 15840 (360%)

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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of 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.
