We ran two DiRT 3 benchmarks to get an idea for CPU bound and GPU bound performance. Lightly threaded performance is simply not a strength of AMD's FX series, and as a result even the old Phenom II X6 pulls ahead. We see similar results under Dawn of War II. In CPU bound environments in Crysis Warhead, the FX-8150 is actually slower than the old Phenom II. The FX-8150 is thankfully a bit faster than its predecessors, but it still falls behind Sandy Bridge. Looking at the no render score, the CPU standings are pretty much as we'd expect. Within each family however there is no advantage to a faster CPU, everything is just GPU bound. We've seen this in the past where one platform will hold an advantage over another in a GPU bound scenario and it's always tough to explain. While we're GPU bound in the full render score, AMD's platform appears to have a bit of an advantage here. However it is useful to look at both CPU and GPU bound scenarios to paint an accurate picture of how well a CPU handles game workloads, as well as what sort of performance you can expect in present day titles.Ĭiv V's lateGameView benchmark presents us with two separate scores: average frame rate for the entire test as well as a no-render score that only looks at CPU performance.
AMD clearly states in its reviewer's guide that CPU bound gaming performance isn't going to be a strong point of the FX architecture, likely due to its poor single threaded performance.
