Benchmark Results: Grand Theft Auto IV

Part 1: Building A Balanced Gaming PC
By

Grand Theft Auto IV

The amount of available memory for each graphics core determines the detail levels Grand Theft Auto (GTA) IV allows to be used. Rather than bypassing this constraint, we basically cranked settings for the 896MB per GPU available on the GeForce GTX 260 and GTX 295. Note that, here, if you were using cards with 1GB per graphics processor, you could further raise Shadows to Very High and set view distance to 30%.

Even at the lowest resolution, the Radeon HD 4850, with only 512MB of memory, needed to be omitted from GTA IV testing.

I was totally new to the GTA series when I started work on this project. But having heard the voices of readers wanting to see this game added to the benchmark suite, I obliged. The first order of business was to play the game on various configurations and get accustomed to the expected performance and hardware requirements. We again use the game’s built-in benchmark and shoot for a target of 40 FPS. Some time spent playing on our tested platforms indicated that systems capable of reaching this target were at least playable, providing 30+ FPS during intensive game play, with just the occasional dip into the mid 20s. Whether in-game or running the benchmark, GTA IV doesn’t seem push graphics cards all that hard.

A quick glimpse at this chart is all that it takes to see GTA IV is the most CPU-limited game we have visited thus far. It’s also obvious that the game takes advantage of more than two processer cores. A closer look reveals the two dual-GPU cards actually trail behind at this low resolution. 

The stock 2.8 GHz Pentium E6300 doesn’t have a shot at competing here. While the GeForce GTX 260 and Core 2 Duo E8400 are the cheapest pair to hit the target, we also see it takes a pairing with one of the quad-core chips before we call a GeForce GTX 260-based platform balanced.

The CPU bottleneck continues, and despite slightly lower results for the GeForce GTX 260, our recommendations remain the same.

Other cards start feeling some pressure and the GeForce GTX 295 eventually climbs to the top. But overall, for a third straight resolution, our hardware recommendations remain the same. Note how CPU-limited we still are at 1920x1200; the y-axis scale still doesn’t even need adjusting.

At 2560x1600, the GeForce GTX 260 can no longer reach the target frame rate, while its bigger GeForce brothers easily take the top honors and deserve attention. The Radeon HD 4870 X2 doesn’t look as impressive here as in other games, but the Radeon HD 4890/E8400 combo manages to be the cheapest and most balanced minimum solution we can recommend at this resolution.
