Sounds like quite a leap to make IMO.

Wow, what a low generalization based on one bad system which probably is due to user error anyway.

Only if your 3rd party information would be correct wink.gif

The 4x512KB L2 block is 13.735mm², each core takes 3.067mm² >> 6.5mm² per functional core.

You can easily see from the poly shot that the L2 isn´t anywhere near "little less than 10mm²" rolleyes.gif

Can you give a link?

10.86mm^2 for 2Mb of L2.
= 2.715 + 3.1 = 5.815mm^2 for Jaguar.

Anyway it doesnt actually matter. I might be wrong about this... jaguar core shows that AMD can do small, efficient, fast core.

No this was 5 separate systems. All different generations and chipset versions.

Why is it news to you that a SOC is smaller than a CPU? Do you understand the difference?

I already own 5820K so I rather won't change to AMD on zen release.

But I was using amd on my main machine for a while(5 years on PhenomII 965/1045T) so I hope they succeed. Maybe then I will be able to go AMD in some time in the future.
For now my only amd machine is my HTPC running Turion X2.The rest of my amd hardware is separate parts.

Haswell core is 14.5 mm^2 - without L2
- Each haswell core has 512 mb of L2.
- If we compare core size with L2 and performance... then also add L3.

Conclusion : AMD Jaguar core is pretty awesome.

Image of core die size

You seem to be missing the point, clearly. Alright, because Intel offers far superior performance per watt and because of a lower manufacturing process they can permit more execution units which logically will consume more space. (Comparing the x architectures at the same manufacturing process). First of all, the jaguar back-end looks empty and secondly it's garbage compared to Core 2.



I mean, there's like nothing in there.




Jaguar is a really bad architecture, it can't even compete with a 11 years old architecture. Also, don't you think 512MB of L2 cache is amazing? It's 256KB per core, FYI.

Here is the poly shot for Mullins. The die layout and sizes for Kabini are identical.



When the die size is 107.12mm², you can see even from that picture that the L2 is >13mm² in total.
