XFX HD 5750 740M XXX 512MB beats reference HD 5750 1024MB

Index








Throughout gaming tests, we’ll try to show the dependence of HD 5750 on the amount of memory. XFX HD 5750 512MB XXX card comes with 512MB of memory, which is half of what the reference HD 5750 brings. Naturally, any assumptions of performance dominance go straight out the window after you consider the fact that the XFX HD 5750 512MB XXX comes with higher operating clocks that secure initially superior performance.

The results show that the HD 5750 740M 512MB XXX manages to beat its reference counterpart at 1680x1050, but not on 1920x1200. It’s well worth noting that this exception stands only in Crysis, whereas the rest of the games scored better with HD 5750 740M 512MB XXX. Naturally, the 2560x1600 resolution, detailed textures and antialiasing have proven to be too tough a nut to crack for the HD 5750 XXX’s 512MB of memory.


Far Cry 2

The HD 5750 740M 512MB XXX outpaces the reference HD 5750 1024MB by about 5% without antialiasing, but it manages to score nicely with antialiasing as well, except on 2560x1600 where 512MB is obviously not enough to churn out a playable framerate.

Dirt 2

Dirt 2 allows for gaming at 2560x1600 but only if you turn antialiasing off. The XFX HD 5750 740M 512MB XXX’s 512MB frame buffer obviously isn’t up to the task of tackling such high resolutions, but managed to outscore the reference HD 5750 1024MB by up to 3.6% in the rest of the tested resolutions.

Compared to the reference HD 5770 1024MB card, the XFX HD 5750 740M 512MB XXX is some 13% behind.
