Amd Modules vs Intel Cores?

[Edgar R. Zakarian]

The question is inspired from this:

 "Integer cores yes. Floating point Cores no.

Just to be comparative:

An AMD core has one integer unit (not sure what it's meant to be called) and shares a Floating point unit in a module.
An Intel core has one integer unit and one floating point unit."

http://www.tomshardware.co.uk/answers/id-2135612/intel-4770k-amd-fx8350.html

 

 

Doesn't the above just mean, that my FX 8350 actually has one core, which is hyperthreaded, for each modules? A total of 4 modules.

 

Meaning 4 cores hyperthreaded?

Yes, almost like that. AMD is 4 modules 8 cores with shared resources. 

Intel has 4 cores and shares resources to make another 4.

 

AMD modules was a big failure. On release fx processors got smashed by phenoms...

AMD should have just folded and refreshed phenom then they might have competed with atleast an i5.

Sounds like a way to trick consumers :lol:

hmm. fascinating. I don't think you should look at it that way. a core is a core, it just has to share resources, but unless you are doing primarily floating point math(which I avoid in programming as floating point has pesky rounding errors) it wouldn't be the primary cause for it being slow, or at least that's my guess.

I think it is just one of many reasons why an intel quad dominates an AMD 8 core CPU.

Is it just the architecture then ?

-But as the other website explains, both CPU's have one core, and one float point unit, correct?

So a "module" in AMD is basically what Intel calls a core + hyperthread ?

Pretty much.

[Edgar R. Zakarian]

Pretty much.

Okay, great, so my AMD "8-core" is a 4-Module CPU, meaning 4 cores 4 float point units.

So 4 Cores Hyperthreaded. In a sense it is good, because most new games will be able to use the 4 CPU's as it's not actual 8 cores.

Downside, is that it won't last as long as i thought. Thought when I invested in this CPU, this CPU would just stay in the medium range, as games would use more and more of its cores. :lol: Damn.

Remember:

Dx12 will not multithreaded games.

It is designed to mainly move the graphics stack from core 0 to all available cores. This has the effect of reducing drawcall bottlenecks, something that's not terribly common. It doesn't magically make the program run across all the cores, just the draw requests sent by the CPU. It is still up to the game developers to process their game data, logic, AI, and whatnot across all cores.

DX12 does not just make things multithreaded.

The benchmarks that you've seen based on it are about draw call bottlenecked situations, mostly to make M$ look good.

Wait until it comes out to see the effect on current hardware, and whether or not devs will get off their asses.

Thanks bro, but I bought this before I even heard about DX12, was just thinking, the standard is Quad Core now,

in a few years It'll be Hexa, then Octa. So I should've been all set haha :lol:

 

How did you make your footer though? I'd like to have my hardware in the footer too, to help people instead of writting Down a list every time I ask for help.

(Assuming desktop PC, else just use full version of site)

Go to your profile, middle of page, to the right side should be edit profile, on left side after clicking that should be signature, just click there, and it brings up a spot to put things in your footer. If on PC you get full options for colour and stuff too.

And I was just trying to make you aware of what dx12 actually does. There's a lot of stupid uninformed hype around it.

Thanks, I've added it now :-D - BTW you're missing your GPU in signature

[FruitBasketSilex]

Thumbs up.

Glad I could help you.

Actually, the biggest bottleneck in DX11 and older is that the GPU can't even make as many drawcalls as it's able to. Regardless of CPU. The CPU load spectrum widening is another benefit. But the primary bottleneck was the GPU being held back in terms of draw calls being made, not the CPUs execution of those draw calls (unless the CPU was even too weak for the 10K draw calls coming to it)

 

Hence, DX12 will boost old GPUs as far back as GeForce 8800/ radeon 4xxx as well as multicore CPUs. Even an Athlon X4 + GTX 470 will become a powerhouse (minus VRAM for textures, filters and shadows of course being a bottleneck) compared to today's performance in DX12 games.

I assume you have evidence to back up your claims?

Quoting the AMD developer conference from a while back. The developers of that spellcrafting game claimed an R9 290 was only able to make 10K draw calls under DX11 and ten times as many in DX12 and Mantle.

If you can find an article or slideshow about it I would like to read it.

It was streamed on YouTube and should be under AMD's channel.

Will all this mean, that my 6990 will also benefit from this then? Combined with my FX8350 CPU? :lol:

Also, does this apply for older games too (dx-10+11 games) or only games that are programmed for DX-12?

Only games developed for dx12, old games will not get a magic re-coding to a new api, obviously.

I'll look for it tommorow.

awww, haha, but yeah, as expected I guess . :lol:

At least the old GPU's will also be usable and not totally in the dust of the new fully fledged DX12 Cards.
