AMD FX 8320 analysis

Sorry i am really starting to drag this thread off topic ALXAndy i really am sorry as mentioned the device i need to use to type wont let me start my own threads and i dont know anyone here to ask them to post one for me.

So a seperate sound card is still worth getting despite good onboard sound?

Allow 8 gig will be enougth despite some games wanting 6 gig minimum

A discrete sound card is the sort of thing you don't realise you need until you have it. Even with the crosshair, the difference in quality is pretty vast.
 
Yeah I noticed that when I first used a Xonar DG, although it was PCI and I had a board with no PCI when I switched to a 2500K from my CH IV.

The Xonar DG now has a PCI-E one.

COH2 tends to be bound a bit by single threaded performance, but if you OC it's fine:

I know its an old post but this looks totally gpu limited for the Intel. (Except AMD CPU's at lower clocks) There is no way a Titan or COH2 bottlenecks a Haswell i7. What truely amazes is that even an overclocked AMD does not attain the same or better fps levels of an i7 even when clock by nearly twice the cpu frequency. Totally remarkable.

Given the Intel scores, the Titan is the bottleneck.
And it's likely if you ran the benchmark again, you could probably get the 41 FPS on the FX83, 40/41 is margin of error as far as I'm concerned.

40 fps 41 fps isn't really 'not the same'. FX CPUs don't do well at lower clocks in certain games, that's nothing new, it means here the 83xx needs somewhere between 4-4.5GHz to remove the bottleneck. (Not that this has much to do with this topic.)

At £250-275, you left off this fix:

:cool:
 
But you won't need the i7, the i5 ; 2500k/3570k/4670K will all be doing that 41 FPS probably at stock given the 4770K is doing it at 2.5GHZ, and it's obviously not scaling with the threads that well in their sequence.
 
I put up that benchmark (the worst I've seen) to avoid accusations of cherry picking - others have better results, which might mean the game was patched after techspot did their review. Those results strongly indicate it's relying on single thread performance, despite running on other threads too (CPU analysis would likely show one core at near 100% the others much lower, until >4GHz).

Yea. That bench on the Intel rig is totally GPU limited and bottlenecked by the Titan. This is because in that particular bench with max setting, SuperSampling AA is applied (which kill graphic frame rate hugely).

People really need to learn how to interpret information from graphs properly and realise what they are actually showing. The FX8350 needed 4.50GHz to match the i7 4770K at 2.50GHz before able to reach the GPU limit at 41fps. What this also means is that for the FX8350 at 4.50GHz, dropping from max settings down to medium to reduce GPU limitation will not increase frame rate much due to CPU bottleneck; the i7 4770K on that other hand would have frame rate increase to greater degree due to the GPU bottleneck being reduced. Even if not dropping graphic settings, overclocking the Titan or using a GTX780Ti would most like see the i7 getting higher frame rate (was gonna say adding another Titan to SLI, but then I remember COH2 barely support multi-GPU), while the FX8350 at 4.50GHz would not.

I think someone said that COH2 was optimised for 8 cores? From the looks of the review, particularly the CPU usage, it looks more like it's using up to 4 threads max...

Agreed,
But can you just imagine the lead if 2-3 Titans in sli were used. (You would need an i7 for sli though).

From the graph above at what frequency would the haswell achieve 40fps, speculation maybe 2.0Ghz, maybe 2.2Ghz. Either way the IPC is totally amazing. The AMD looks pretty poor. Imagine the power a haswell at 2.0Ghz draws 35w. lol

I've got a boxed mint condition XFI Fatal1ty FPS with the front box thing. Sadly it's PCI so I can't use it. In my rig I have no PCI and in my lady's the coolers block all of the PCI slots :(

Can't bring myself to get rid of it though as it's gorgeous.

We don't know if we need an i7 for SLI, it wouldn't do sweet anything over an i5 if the game can't use the extra threads.
And as mentioned it's using an effect that kills the frame rate.

And I can't imagine multi-gpu's working great tbh.
 
COH2 appears to use 1-2 cores predominantly. But as I said, there are other benchmarks that go against techspot's review, e.g.

This would have an 8320 at 4.7GHz outperforming a stock 4770K, which according to techspot, is impossible.
