Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 4870 1GB
IntroThe GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has set the core frequency at 900 MHz. The GDDR5 memory is set to run at a frequency of 1026 MHz on this specific card. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.Compare those specs to the Radeon HD 4870 1GB, which has core clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4870 1GB should theoretically be a bit faster than the GeForce GTX 550 Ti overall. (explain)
Texel RateThe Radeon HD 4870 1GB is a small bit (about 4%) better at texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 550 Ti is much (approximately 80%) more effective at anti-aliasing than the Radeon HD 4870 1GB, and should be able to handle higher resolutions while still performing well. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.

Wow!
I bought the 550 Ti last week... but I didn't realize it would give me such good performance... even for a hardcore gamer like me \m/
🙂
Hello! 😉
I bought recently the ASUS GTX550 Ti DirectCU because my 8800GT 'crashed and burned' and I'm really very pleased with it!
It has an amazing cooling system and allready brings a factory OC, it also has a volt tweak (VCore) to increase performance up to a stunishing 50%!
All these functions are controlled by an ASUS application, you can do it manually or let it auto-configure (like the 'HyperDrive' feature)....and the temperatures are always between 35º/45º, incredible!
In theory, with the OC and VCore enabled, this card can be superior to the 'normal' GTX560....wow!!
