AMD APU vs CPU

[Daniel91]

I want to understand how to compare the AMD's APUcomputing cores to Intels computing cores I searched google but it looked so complicated.

 

I mean my APU's A10 7850K has quad cores and so does my i7 4790K, but my dad says they are totally diffrent. What I don't understand is others keeps saying AMD's APU's computing cores can't come even close to intel's computing cores. And that they are crap for my 3D animation rendering class use.

 

 I really can't see a diffrence after I put in 2133 rams and a R9 290X

 

can someone please explaing the diffrence for me sorry to be a butt hurt to any of you lol

The APU has higher graphic capabilities but is alround a slower cpu when comparing to similar priced cpu's. So on its own a APU is better but with a GPU the cpu is better

Long story short, 1 single core from Intel is heaps better than 1 single core from AMD (At least as of now, 2014). Intel has spent more time on making their cores more efficient and some other stuff, that's what I've heard. Yes, the 4790K will outperform the 7850K in probably all CPU tasks, but keep in mind that the 7850K is for a completely different market and price point, so it's not very fit to compare them.

AMD is weaker on a core-for-core basis due to how they are designed (in modules, they share a few parts) as opposed to Intel (Cores don't share anything except the L3 Cache) The 4790k will destroy the A10 in every possible way except graphics.

It's completely different architecture of cpu. Intel has somewhere near twice the performance be core per clock speed as amd, I can't say I would be able to tell you the difference on an architectural scale but the 4790k also has hyperthreading which can be used for production work, it pretty much increase core utilization because the cpu will have two threads per core giving a constant work flow. So you are comparing cpu with simliair clock speed and core count, the intel is going to dominate it. But it's also why it cost twice more than twice as much

So, let's start from the basics: an APU is simply a cpu with an integrated gpu. That's what amd calls this kind of cpus. In a way, the 4790k is also an apu because it contains a gpu, however intel does not call their cpus that way. Let's move on to cores. A single core can be more or less powerful, depending on the architecture, clock frequency and available cache. The cores on amd cpus (and apus) are not as fast as the cores on current intel cpus (in fact they're significantly slower). Amd compensates for this by having more cores. As a rule of thumb, generally amd's quad cores compare to intel's dual cores in the same price range, however the only real way to compare to cross-brand cpus is through benchmarks. When you are rendering a 3d image, the APU will be much slower than the i7. However, it's possible that the images you're rendering are very "light" and hence both cpus render it very quickly OR maybe you're rendering them on your graphics card: if that's the case, the cpu becomes irrelevant. To see the difference with your own eyes, I suggest you change the program's renderer to cpu and you render a very complex scene or video on both computers. You'll see that the i7 will be twice as fast or more than the APU.

That said, there0s nothing wrong with the apu, it performs in proportion to its price, and it's significantly cheaper than the i7.

APU leverages the Heterogeneous System Architecture (HSA) to efficiently manage workloads in applications. In simple terms, it's designed in APU's such that the processing elements are in the same die (your processor) to efficiently work together.

 

The CPU however, uses a more advanced internal architecture. Which can perform more work per clock cycle than competing processors from AMD.

 

 

tl;dr

i3's are superior than the A10 in completing tasks (although it's dual core with HT in contrast to the quad-core of the A10) due to more work can be done per clock cycle.

A10's are superior than the i3 in the graphics department due to HSA.

 

 

EDIT: Forgot to mention, the A10 7850K specifically make use of the Steamroller architecture which uses 2-core modules which are similar to the Bulldozer architecture (like the FX-8xxx series). And by that, each module in these architectures are considered as dual-core processors. 

tl;dr edit: The A10 7850K isn't true quad core. It's like the i3. (dual-core with HT)

Ok, here's the story. Intel Quad-Core CPU > AMD Quad-Core CPU (Even at different clock speeds). Not trying to sound like an Intel fanboy, but it's simply true. But keep in mind that the AMD cpus are priced lower and they have their own unique place in the market for budget builders.

Intel cores are 'smarter' than AMD cores, say Intel can do multiplication + addition and AMD can only do addition.

 

So you give each CPU 5^2

 

Intel CPU will do 5x5

 

Whereas amd CPU will have to do 5+5+5+5+5 which is going to be slower. 

 

So what AMD could do is make it add faster (more clock speed or cores) but it'd need to be clocked soo much higher.

 

AMD APUs have 12 compute cores (on highest end SKU) which is 4 traditional CPU 'cores' (2 FPUs with 4 Integer clusters) and then 8 GCN CUs (512 cores). Which offers theoretical combined performance of like 900GFlops (off the top of my head a i7 is ~250gflops) which *could* be leveraged in the future using HSA technology.

 

But right now an AMD CPU offers about half the IPC (work per clock basically) of an Intel chip. Which is why AMD 8 cores only compete with i5s in multithreading.

thanks guys for the help for me to understand

1) Intel's Haswell architecture uses full-size cores. When Intel says "Quad Core" it has 4 physical cores. Period.

2) AMD has used "modules" instead of cores in their CPUs since Bulldozer. One module contains 2 integer cores but only 1 floating point unit. When AMD says "Quad Core" they have 2 modules, so it's 4 integer cores but only 2 floating point units. AMD counts the integer cores.

3) The A10-7850K is advertised as a "quad core" because it has 2 Kaveri modules using the Steamroller architecture, and has 4 integer cores and 2 floating point units.

4) However, the 7850K is not just a CPU, it's an APU. That means that it also has 8 graphics cores too. So now it's 4 CPU cores and 8 graphics cores. AMD says that it has 12 compute cores (4+8).

5) The long name for the 7850K is "AMD A10-7850K Radeon R7, 12 Compute Cores 4C+8G"

6) I say that dual core would be the best name for it.

 

Sorry if this was too complicated.
