We're keeping the resolution set to 1920x1080 for BioShock Infinite. To do that, though, we have to adjust the detail level down to Very Low quality. Otherwise, these cards can't handle the workload.


The good news is that every card posts playable minimum frame rates in excess of 30 FPS. The Radeon R7 240, Radeon HD 6670 DDR3, and GeForce GT 630 GDDR5 trail the pack, though.


The frame time variance is also quite low. There are small spikes from the slower graphics cards, but nothing as worrying as just outright slow performance, which is more of an issue with entry-level GPUs.


With the detail setting at BioShock's High preset, only three cards consistently stay above 30 FPS for most of the benchmark: the Radeon R7 250, Radeon HD 7750, and Radeon HD 7770.


The tougher settings are accompanied by significantly more variance in the frame times. Nvidia's GeForce GT 630 GDDR5 and AMD's Radeon HD 6670 DDR3 are particularly affected by the change.

A 400W is overkill if you're running a power-efficient CPU.
Look at the results, the most this system puilled with the R7 240 is 122 Watts under load. That's the whole system, with an overclocked Core i5-2500K!
A good 250W PSU should be fine. AMD is kind of recommending overkill here, but they do that to protect people from poor quality PSUs. A 250W HP shouldn't be a problem as long as the platform isn't power hungry.

You're absolutely right! We fixed the charts, thanks for catching that!
A good 250W power supply will have 18-20 amps on the 12V rail, which is fine for the R7 240.
I don't know why you bring up the 7770, it clearly draws a lot more power than the R7 240.
We were talking about the R7 240, not the 7770.
Even the 7770 is only a ~86W card... just barely high enough to require a 6pin PCIe power connection.
What? What the heck are you talking about?
