No need of two posts to quote what are twin straws....

So set apart putting words into other people mouths what could be your contribution to this debate..?..

Highlighting your struggles with reality.

Games aren't just integer performance or else FX would be right up there with Haswell i7s. FX is an interger moster. I'm talking about instructions per clock, not integer performance clock.

And i also include perf/Mhz, accounting for all cores activity the FX is at 61% of its max throughput while the 2600K is at 72%, let s use this as starting point.


It's not absurd to think the 2600k does more with 69% across all 8 threads (not 71%) than almost 5 cores of an FX-8350 (61%).

8 cores are loaded in th FX and the total loading is 61% of all cores, that s as much throughput than a 2600K working at 72% of its own throughput.



Likely the code is being held back from a single thread that branches off and assigns other tasks. Core one has a 77% load and the other 23% is spread across the "secondary" cores of the modules, but is still held back from the performance of one core. Mantle/DX12 couldn't come soon enough for titles like this.

It s possible but as stated the main thread still manage to get the 7 other cores (plus itself) getting 61% of the CPU total throughput :

Or rather you unability to post something else than an ad hominem, where are you numbers, estimations and explanations..?..

For the time your only contribution amount to thread crapping, as is usual once there s an AMD related thread, so please either discuss the subject under scrutinity or stop this kind of pollution.

The FPS numbers and the CPU utilization are both symptoms of a problem but the cause is still unknown.

I'm betting on PS3 an 360 legacy support.

Lets be frank, it is not true next gen game. They did amazing job optimizing it for newer hardware. It uses 4 threads very well, and shows some benefit with even more cpu threads. But the true next gen title will scale much better with 4+ threads.


Going with the OP tone...
... Intel Haswell i5 4670k - what an utter piece of garbage. It cannot crack 60 fps minimums. I wouldn't put that chip in my garage HTPC. State of the art cpu cannot run smoothly 12 years old ps3/360 port. I bet you couldn't tell a difference if you plugged potato chip in your socket?

Okay, where's the 860k in this benchmark? They benched an FX-4100 but not an 860k? No love for FM2+!

Hell where's any of the FM2/FM2+ CPUs/APUs? Even if you don't like the 860k, there's a lot of 4.5-5 ghz 760ks floating around out there.

I would love to know how my 4.6ghz 760k fairs.

Intel is consistent. AMD isn't. Again. Rockstar put a lot of work into this port and an i5 gets very close whilst AMD lags behind. Again. Wasn't it supposed to be "future-proof" with *snorts* 8 "cores"?

Boy I am glad I made the rational choice and when against my inner fanboy and went with the Intel 4690K instead of the crappy FX 9590. Gives self pat on the back and welcomes ones self to Intel Master Race !

IPC has nothing to do with it, to summarize the FX8350 at 61% of its (integer) throughput is on par with a 2600K that is at 72% of its throughput, so the two CPUs are providing the same amount of computation yet the results are largely different.

Of course this imply that the FX has 20% higher integer throughput than a 2600K, wich is the case.

hyperthreading has potential to add 20% performance.

dual-core in modules have potential to add 80% performance.

With 5 heavily loaded threads, the chip with the HT is going to show as 'more heavily utilized'

To AMD FX credit they due alright but still missing the mark and just a bit less than perfection ... Intel on the other hand 100% perfection as always. I am sure nobody will really tell the dofference beyween an FX 9590 and an Intel Core i5 in GTA V as far as performance goes if they use Vsync ... Heat and power consumption on the other hand well thats another thing LOL.

if this is the case, something you guys would do is disable core 1 to hypothetically give the main thread the entire module. Let the other 6 cores on an FX-8xxx pick up the extra load.

In fact, this is confirmed with the first core load averages across the 4, 6, and 8 core chips:

with a username like that I'm almost certain you seriously considered AMD.

That said, I wouldn't consider the 9590 myself, only the $130 and below FX-8xxx chips. Intel can't match that performance for the money.

Looking at PClab numbers there s quite a discretanpcy in frequency scaling with AMD CPUs despite the GPU not being bottlenecked at this level.

The pentium and i3 scale at as much as 90% with frequency while the AMD are stuck at 50% scaling, wich is not the case on Gamegpu graph that show as good scaling as Intel...

installing this on Win10 with DX12 may grant more performance a la the mantle efficiency gains.

We'll see.

hm. need to see those circled on the graph, I'm not seeing a dedicated test. IE, lets see benchmark at 2ghz and then at 3ghz and then at 4ghz. Let's also see someone overclock module 1 and module 1 only to 5ghz and leave the rest at 2Ghz and see how it scales with a faster dispatch.

edit: ok, so the 8350 vs. the 9590. 4ghz vs 5ghz, 25% performance improvement? No, 40->45fps or 1/8 improvement or 12.5%. So you have a legitimate point.

Can someone with the game do benchmarking? We need to find where the bottleneck is. AMD may have a crap branch predictor causing stalls in the CPU waiting on data. Overclocking the CPU-NB to 2.6-2.8ghz and installing high-speed RAM would tell us if it's mis-predicted branch stalls.

GameGPU is showing 1:1 scaling though.

I didn't think that installing a DX11 game on Win10 would give you DX12 results? I thought the game would have to be built against DX12?

hmmmm

could be patched in.

my understanding was DX12 is basically a software change in a more efficient rendering pipeline, and basically all the DX11.1 cards are ready to go with DX12.

Interesting that FX-4310 @3.8 GHz beats X4 965 @ 4.0 GHz. That should not happen, I would think?

Heat isn't an issue with a cheap aftermarket cooler (freezer pro 7). Even with prime on all cores, 4.3Ghz at 1.4V it doesn't crack 60C. Gaming Starcraft 2 I rarely see it crack 42C and in NBA 2K15 (which is more demanding than this game) it doesn't ever crack ~54C. During cut scenes the CPU usage spikes to ~90% at times.

So 7hrs in, my 780 Ti @ 1215MHz (or 1228MHz) in-game doesn't really go beyond 70% usage with 59FPS Vsync. There are only dips in random sections with grass - forested areas no dips, field + road + desert dips to 50FPS or even 30FPS. This is with AA disabled except for MSAA reflections @ 4x and everything set to Very High with maxed out sliders. No dips in Los Santos itself. If I disable Vsync there are dips to 50 ish and usage hits over 90%, FPS then crack 100FPS in other areas. 5930K on the other hand @ 3.7GHz varies between all cores loaded and 4-5. Echoes of Crysis 3 where the grass flattened FPS.

I think that this still needs some performance and stability patches (had 3 crashes today myself). It IS CPU heavy though.

In fact, this is confirmed with the first core load averages across the 4, 6, and 8 core chips:

core load from task manager does NOT show you the "real" utilization,
example from battlefield 4 ~90% on each core ,for the quad,does not mean that all 4 cores are being used 90% all the time,you have the main thread maxing out a core and the rest of them being filled up relative to the main thread.


right side you see task manager showing ~90% on all cores on the left side you see the actual threads,one thread at 22,5 of 25% total,and the rest much lower at 14-15% ,so the FPS you will get is bound by how fast your main thread will be able to run.

That doesn't mean that any old DX11-api-using game will gain the benefits of the DX12 API (low-level, etc.). It has to be re-coded.

I recently went with the i5 4690K and Z97X platform just before last Christmas because it offers the best gaming performance for the money period. I really wanted my dream of a maxed out 5Ghz AMD FX chip but for the cost, overall performance, efficiency, platform features like M.2, power consumption and cooling needed I choose the Intel platform this time.

Ah you need max OC on an AMD FX CPU as they are very slow on per core performance and IPC which means a high end cooler and PSU is needed. That's why I went to Intel this time around. If/When AMD comes out with a new beast CPU I will go back to them as I am an AMD Fanboy.
