A Question

Compare any two graphics cards:
VS

GeForce GTX 460 vs GeForce GTX 550 Ti

Intro

The GeForce GTX 460 comes with core clock speeds of 675 MHz on the GPU, and 900 MHz on the 768 MB of GDDR5 memory. It features 336 SPUs as well as 56 TAUs and 24 Rasterization Operator Units.

Compare that to the GeForce GTX 550 Ti, which comes with core speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs as well as 32 TAUs and 24 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.

It seems that the 550 Ti uses a third less power and beats the 460 2 out of 3 catagories. Less cores but greater performance, 550 Ti is the winner.

Jack says:

Nope your wrong GTX 460 is more powerfull

Frank says:

Nope, you're both wrong. Intel HD is the king.

Frank says:

This comparison is done with the weaker 768mb GTX 460...

Not the standard one with 1024mb 256bit memory at 115200 MB/sec.

jajaja intel hd

Intel says:

Intel HD FTW! HAHAHAHA!

Man says:

Intel HD is the absolute pinnacle of performance. Definitely Intel HD for the win.

Johnny says:

Intel hd? Kkkkk... 550Ti win! In this comparation (: but..

thaghost says:

I only wish I could afford something with Intel HD, It's some top of the line stuff.

Assassin says:

Intel HD is effective but not as much as GTX 550 ti It has only one thing less which is Texel rate & due to less power cosumption it wins...

Jax says:

Lol intel HD.... That's so funny
