GeForce 9800 GT 1GB vs GeForce GT 1030

Intro

Compare all of that to the GeForce GT 1030, which features GPU clock speed of 1265 MHz, and 2048 MB of GDDR5 RAM set to run at 1502 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 32 Texture Address Units, and 16 ROPs.

Texel Rate

The GeForce GT 1030 will be a little bit (approximately 20%) more effective at AF than the GeForce 9800 GT 1GB. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 6880 (20%)

Pixel Rate

The GeForce GT 1030 should be a lot (more or less 111%) more effective at FSAA than the GeForce 9800 GT 1GB, and also should be capable of handling higher screen resolutions better. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 10640 (111%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 in a second.

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