AMD FX Vs. Intel Core i3: Exploring Game Performance With Cheap GPUs

Features
By published

Following our sub-$200 gaming CPU comparison, we put Intel's Core i3-2100 and AMD's FX-4100 under the microscope. This time, we test a number of different graphics cards from AMD to see how GPUs affect perceived processor bottlenecks.

Benchmark Results: StarCraft II

Performance Target: 30 FPS Minimum

Finally, let’s consider StarCraft II, a real-time strategy game notorious for its processor dependency. We start with the 30 FPS minimum frame rate target.

Our minimum goal of achieving 30 FPS proves irrelevant, as the demanding benchmark we use pushes both of these CPUs to their limits. The Core i3's advantage is clear. There’s no point to running a second set of benchmarks targeting 40 FPS when we can’t keep these platforms over 16 FPS, regardless of settings or resolutions.

To the FX-4100’s credit, this is a very demanding benchmark, and most StarCraft games won't push a machine quite as hard. There are some custom maps that tax processor performance, though, so the benchmark's validity stands. If you're wondering why the frame rate climbs over time, that's because units are destroyed and removed, alleviating the load. Regardless of the caveats, Intel's Core i3-2100 shows itself superior in this title.

    Great...AMD is still capable.

    Whats with the line graph Don, it's hard to read especially with the choice of color on the lines. Bring back the bar graphs.:)

    This is a great article, Toms needs more budget rundowns like this and perhaps more games in the test sweet that exploit the cpu difference more...

    I think if you're really budget limited, but need to build a system today, buying 1155 makes a little more sense. Get a decent motherboard, then get an 1155 Celeron G530/540 or Pentium. Then save up some money, and upgrade to an Ivy Bridge CPU later. The i3 is great, but the i5s are a much better deal $/performance.

    So if you need a new system and can't afford an i5, just buy a cheap 1155 SB as a placeholder until you can . Like the conclusion states, the upgrade path is there -- I just think that if it's a temporary step, you might as well save $60 to $80 if you're upgrading in the next 4 months anyway. You'd be surprised how fast the SB budget parts are, and they're fast enough to get you through till IB.

    would be nice if more benchmarks were done, there are a lot of popular games that would be nice to test like civ 5, l4d2 or similar source game, mw3, SWTOR ect. Even if some of them aren't the most demanding games it would be nice to see them as they would be more relevant than dirt 3 or battlefield 3 single player.

    It would be nice if they through Civ 5 or MW3 in but at least on the FPS front, I think BF3 has a bigger following on the PC and the same thing goes for Skyrim. Not sure how many people are still playing Just Cause 2 though. In either case, I think this has more to do with being able to compare these results to the results from past benchmarks they've run.

    The line graph is better way to show it's behaviour over a period of time rather than a flat average, which doesn't explain frequent dips or long stretches of smooth gameplay in fps and such.

    A very informative and realistic article, nice work Tom's. Lets hope AMD has something with piledriver.

    Sucks that the Core i3 can't be overclocked like the legendary e4xxx series or the e2160 which you could get a 100% OC with.

    If DC Sandy Bridges could be unlocked, they would be so good for gaming.

    Love the FPS graphed over time. Keep using them!
