GeForce GT 1030 vs GeForce GT 340

Intro

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

Compare all that to the GeForce GT 340, which features clock speeds of 550 MHz on the GPU, and 850 MHz on the 512 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 should be quite a bit (about 130%) faster with regards to anisotropic filtering than the GeForce GT 340. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the GeForce GT 1030 is a better choice, by a large margin. (explain)

GeForce GT 1030 20240 Mpixels/sec
GeForce GT 340 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 largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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