VS

GeForce GT 450 (OEM) vs GeForce GTX 465

Intro

The GeForce GT 450 (OEM) comes with a GPU clock speed of 790 MHz, and the 1536 MB of GDDR5 memory is set to run at 1000 MHz through a 192-bit bus. It also is comprised of 144 Stream Processors, 24 TAUs, and 24 Raster Operation Units.

Compare that to the GeForce GTX 465, which uses a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 memory works at a frequency of 802 MHz on this model. It features 352 SPUs as well as 44 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM) 106 Watts
GeForce GTX 465 200 Watts
Difference: 94 Watts (89%)

Memory Bandwidth

The GeForce GTX 465 should in theory perform a little bit faster than the GeForce GT 450 (OEM) in general. (explain)

GeForce GTX 465 102592 MB/sec
GeForce GT 450 (OEM) 96000 MB/sec
Difference: 6592 (7%)

Texel Rate

The GeForce GTX 465 should be a lot (about 41%) more effective at texture filtering than the GeForce GT 450 (OEM). (explain)

GeForce GTX 465 26708 Mtexels/sec
GeForce GT 450 (OEM) 18960 Mtexels/sec
Difference: 7748 (41%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 465 is superior to the GeForce GT 450 (OEM), not by a very large margin though. (explain)

GeForce GTX 465 19424 Mpixels/sec
GeForce GT 450 (OEM) 18960 Mpixels/sec
Difference: 464 (2%)

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 (measured in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
