Discrete GPU Gaming

When comparing CPUs to APUs, one strength shown by team Blue in the past is the discrete GPU performance. However even when using dual graphics cards at a 1920x1080p resolution, we seem to have hit a wall where extra CPU performance does not necessarily translate to more frames per second. Our results below show little difference between the Haswell processors, and we need to go down to a 2.0 GHz i7 or a 3.5 GHz i3 CPU to see a significant drop in frame rates. The biggest benefit from overclocking seems to be F1 2013 minimum frame rates.

    Dolphin Benchmark: "...and general reports tended to suggest that Haswell provided a significant boost to emulator performance."

    Boy, I'd say... My i5 2500k at 4.5Ghz took 9.87 minutes. Beat out by an i3, sheesh!

    oh, also want to add that haswell-e seems to be what people are waiting for since it will offer 6-core as base and a new 8-core cpu as well as supporting ddr4. but, i'm also waiting for AMD's answer to desktop cpu. they already have an 8-core processor. i feel like if they update the chipsets, add pci 3.0, maybe even ddr4 support as an option, improve the FX series 8-core processor to be equivalent or near haswell-e or even ivy-e 6-core,--it would really give intel a run for the innovation/awesome cpu maker spot--but i know i'm dreaming.

    AMDs chip lies between a true 8 core, and a 4 core with hyperthreading. It has enough hardware for 8 full integer cores but behaves more like hyperthreading with the 4 shared floating point modules.

    oh, does anyone know if AMD has better TIM on their FX series cpu's?and/or have the IHS soldered?

    What I want in a discrete graphics or a APU is High quality HEVC 1080p encoding with the speed of quick sync as I have to rely on X264 encoding. Otherwise buying a new CPU has no point for me. Sandy Bridge still provides great performance at 5.5Ghz good enough for gaming and hopefully at the emergence of DX12 CPU limited scenarios will be in very few circumstances.

    Somehow it feels like Intel are really bored and struggle to present something interesting. I mean, One would expect Broadwell to be around the corner or at least some Iris Pro love in a socketed chip just to compete with AMD in the only area they are not dominating right now. At least in Atom chips things are more interesting lately.

    You know, they make marker pens that have nibs that are less than 0.5cm across ;-) How do you ever read what you scribble on cpus?

    yeah. it's called a sharpie. lol!
