Radeon R7 240 And 250: Our Sub-$100 Gaming Card Round-Up
By

Assassin's Creed IV: Black Flag is a beautiful-looking game. But it's also quite a challenge graphically. We had to drop the title's detail settings as low as they'd go at 1280x720 to give these entry-level cards a chance.

The Radeon HD 6670 DDR3 outperforms XFX's Radeon R7 240 by a small amount, though it's significant enough if you consider 30 frames per second as low as you'll go for a smooth experience. Nvidia's GeForce GT 630 shows its age, but the rest of these cards perform quite well.

Frame time variance is very low across our tests, which is ideal. Raw performance is the limiting factor in this game.

Can any of these cards contend with an increase to 1920x1080?

Only the Radeon R7 250, HD 7750, and HD sustain minimum frame rates close to 30 FPS at this resolution.

Despite low frame rates, variance isn't bad at all.

    My brother has a HP s3500f slimline computer that I thought the R7 240 might work well in (at least better than the Geforce 6150se it has now).

    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.

    Where do you get that 400W figure from that Guru3D article? The highest measured figure in there says: "System Wattage with GPU in FULL Stress = 231W" and further down they say they estimate the board's power to max out at ~86W which is just above 7A.That would be power measured at the wall which includes PSU losses... and their test system includes water pump for their OC'd i7-965, cold-cathode lighting and a bunch of other unnecessary stuff most low-end systems would not have that brings their idle power up to a whopping 155W instead of the 50-80W range for typical for current Intel-based mainstream setups.

    Just buy a bigger PSU and be done with these poor performance-for-the-dollar/watt cards.

    These discrete cards that squeeze frames out with very little power drain are great. I recently bought one such cheap AMD-card for my fiancée when she wanted to play Guild Wars 2 with me. Having an aging low cost workstation with a weak power supply "Made in Hell", cards like these were the only option. At least without having to upgrade and tweak other parts of the PC. (Yes I'm lazy [and like to save money]).Don Woligroski: For the few(?) that are in the same situation as me it would be great to se an efficiency chart. Like average frames pr. average watt usage through a benchmark, or something in that vein.

    Cleeve.... not true:http://www.guru3d.com/articles_pages/amd_radeon_hd_7750_and_7770_review,7.htmlA stressed 7770 Requires at least a 400W good PSU (Note that 400W DOES NOT mean 400W on the 12V rail, but 400W in total. If you do that math in a 250W supply you get a lot less power on the 12V rail, who knows maybe 170... Also remmber that the GPU needs a fixed amount of power in a defined amount of cables. This means that if the PSU is not good, it wont be able to juice the GPU well enought).

    In Metro: Last Light, the GT 640 gets exactly the same FPS and frame time variance at both 720p and 1080p. It looks like you accidentally input the data from one benchmark run in both places.

    *EDIT BY EDITOR*

    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.

    Thing is while the 7770 offers better performance it also offers a higher power consumption meaning most people who are just grabbing a graphics card for a prebuilt system will not be able to use the thing with out a psu upgrade which now means you should just get a better card since you are spending more money.

    Think the question is what card/configuration is most sufficient/efficient/performance setup for Crossfire . With two of the R7 250s you have twice the GCNs. Which is better than that of the R9 270x. Or the same. However the card,mb configuration may not be adaqaute, or the price performance ratio might not match your requirements. Have read where the new A10 kaveris,can 'only'use the DDR3 type R7 240,250s. So there is a little consideration here for this. Some info from: http://wccftech.com/amd-kaveri-dual-graphics-works-ddr3-memory-based-radeon-r7-gpus/

    How about R7 240 DDR3 vs R7 240 DDR5 vs A10 Kaveri?

    The 7750 maintains a solid 10% edge over the R7 250, keeping it's crown as the most powerful low-profile, no extra power GPU on the market. With no fab shrinks expected until fall this doesn't look likely to change. Even if the R7 260 matches it in shaders it is unlikely to get much of an edge without adding external power.

    Hopefully with 20nm coming the 7750 and 7770 will be at the 340 and 350 positions respectively. That'd be a massive increase in value.

    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.

    @blackmagnum, and how would you do that whilst staying under $100, exactly?

    I just wonder why are there no tests at lower resolution? Games look a lot better when they run smooth in lower res with a bit of smoothing then choppy in HD.

    What? What the heck are you talking about? :pt1cable:

    Because we want a sense of the entire sub-$100 graphics card market, we're generating two sets of benchmarks. For the first set, we're dropping detail settings and resolutions to the point where very low-cost cards can contend (down to a minimum of 1280x720). The next set is at 1920x1080 at more demanding detail settings.
