Review: More for less


GTS 450 was launched soon after the widely acclaimed GTX 460 card, where we have decent performance at reference clocks, quiet operation as well as overclocking potential. Even more so, some partners dared to push the GTX 460's GPU to 850+MHz and back it up with a warranty.

Our EVGA GTS 450 showed nice overclocking potential, but we expected that - some partners pushed their cards to as high as 925+MHz. GTS 450 can run even faster though, as our result of 970MHz GPU proves.

Let us remind you that reference clocks on GTS 450 cards is 783MHz whereas EVGA GTS 450 FPB comes with a 823MHz GPU.  The memory runs at reference 902 (3608MHz effectively) but we managed to push it up to 1090MHz (4360MHz effectively).

GPU temperatures on EVGA GTS 450 FPB card go up to 70°C with idle temperatures hanging around 28°C.

EVGA GTS 450 FPB uses reference cooling, with the fan spinning at 30% RPM and running really quiet, even when you put your ear closer to the card.

During our overclocking we pushed the fan as high as the card's BIOS allowed which was 70% RPM. Unfortunately, the card became pretty loud but in return our 970MHz GPU temperature was at 63°C. Naturally, you can always fine tune the noise-performance ratio and tailor it to suit your needs.

Idle consumption is a bit lower than on HD 5770 or HD 5750, but this figure rises during operation and consumption ends up higher than on HD 5770.

Geforce GTS 450 is an affordable card that features DirectX 11, CUDA, 3D Vision and PhysX support. The card’s performance is somewhere between the HD 5750 and HD 5770, which doesn’t make things easier for end users, especially considering that this price-range is usually dictated by the-cheaper-the-better rule.


When amd releases next gen cards (next week) they will also support 3d glaces. Also opencl matures and more and more companies will support it (making cuda obsolete because nvidia also supports opencl). Finally physx will be replaced in the future with something else (like havok). So what will nvidia do then?

focus on speed/effeciency with 28nm, and focus on tegra 2/3 stuff. what else are they doing? Unless they have more money to blow to give to developers to support PhysX.
