intel HD Graphics vs. Discrete GPU - Gaming
For this next set of tests, we pit the integrated processor graphics incorporated into the Ivy Bridge-based Intel Core i5-3470 against a couple of the least expensive, current-generation discrete GPUs from NVIDIA and AMD, the GeForce GT 430 and Radeon HD 6450 and Radeon HD 5550, respectively. A couple of Sandy Bridge-based processors with integrated Intel HD 3000 series graphics and the Core i7-3770K with the HD 4000 are thrown into the mix as well.
According to 3DMark Vantage, the Intel HD 2500 series graphics engine offers roughly half the performance of the HD 4000 and finishes just behind the HD 3000 when paired to the Core i5-2500 (CPU speeds affect this benchmark). All of the entry-level discrete cards were significantly faster.
In our in-game tests, we've also included a few numbers for the Core i5-3470 / HD 2500 running without any anti-aliasing enabled. Regardless, in-game performance is significantly lower than the HD 4000 and playable framerates at a full HD resolution are not likely with most games.
