News Core i7-13700K Allegedly up to 60% Faster Than Alder Lake With DDR5

[Admin]

New Chinese benchmarks show serious multi-threaded and DDR5 memory performance improvements with the upcoming Core i7-13700K and Core i5-13600K.

To the writer: I believe your wording is off with the percentage of improvement. The amount of improvement is against the baseline of 100%, not as a whole against the results. As an example, here is one of your sentences:

"The 7-Zip results are particularly interesting, with the 13700K absolutely dominating the compression results with a whopping 164.84% improvement over its predecessor in the DDR5 tests ..."

This sentence and other similar sentences throughout the article incorrectly uses the percentage of improvement. The 13700K did not more than double the performance of the 12700 as "164.84% improvement" would mean; instead, it only went another 64% past the baseline 100%. So your article title is worded correctly, but many sentences in the article itself are using the wrong percentage of improvement.

So you're telling me, the 13700k is faster in multicore tests than the 12700k? Must have something to do with comparing a 16 core chip vs a 12. I would hope it's at least 25% faster

The only relevant info here is single thread tests and clock speeds.

You have started with 12cores and added 4 more cores so you have added 33% more cores.
So I would have thought it should be at least 33% faster in multicore score to full value from those extra 4 cores ! 😄

It's 8P + 8E (13700K) vs 8P + 4E (12700K).

Keep in mind E-cores are lower power / lower clock / lower IPC than the P-cores. Raptor Lake's E-cores are the same as Alder Lake's, but the Raptor Lake P-cores are new.

Adding 4 E-cores with no additional clocks might maybe give you 20-30% in multi-core on an Alder Lake rig.

In their chart for multi-core, the worst the 13700K is doing is +28%, and in one case the 13700K is s getting almost +65%.

That is not explainable by just adding 4 e-cores.

It also seems to be getting 7%-11% higher performance from single core workloads.

Looks like someone is misinterpreting percentages
Please correct or something before people go and spread "Wowzer!!! DDR5 = 167% better!!" haphazardly

To say 167% of something, means that specific value (100%) and THEN 67%
To say 167% more of something means 167% of that value ontop of itself.
e.g. 110% of 100 is 110
110% MORE than 100 is 210.

Strictly speaking their title is not false.
7-Zip Compress :
12700K DDR4 = 100%
13700K DDR5 = 164.84%

So a 13700K with DDR5 is in fact 64.84% faster than a 12700K DDR4 rig, or 164.84% of its speed.

This is all a bit misleading though because doing apples to apples :
12700K DDR5 = 140.51%
13700K DDR5 = 164.84%

So in 7-Zip, really the 13700K is getting its boost from the additional 4 e-cores, because 7-Zip likes more cores and likes DDR5.

The other more 'IPC' intense and less 'cores+clocks' benchmarks show some pretty hefty boosts though which are not explainable by just adding e-cores to a gen 12.

Being an unreleased engineering sample I would say that clock speeds are irrelevant.

They're adding 4 ECores which aren't hyperthreaded. So you're starting with a 20 thread CPU in the 12700k and moving to a 24 thread CPU in the 13700K. Only 20% more threads.

The hyper threads only boost it like 20% compared to proper cores so I wouldn't consider it to matter nearly as much! It will help a little bit but only minor . So i believe it would be more realistic to just stick to the cores for comparison!

Sure, the hyper threads only add 20% ,the e-cores are only ~20% slower(or 30-40% compared to full speed single thread) ...who cares, they are all cores right, what 40% difference!? It's all the same thing.
If I have 4 $100 bills and you have 4 $10 bills then you and I have the same amount of money, right?

In the aggregate scores, an E-core is roughly 54-64% of a P-core, however this percentage can go as high as 65-73%. Given the die size differences between the two microarchitectures, and the fact that in multi-threaded scenarios the P-cores would normally have to clock down anyway because of power limits, it’s pretty evident how Intel’s setup with efficiency and density cores allows for much higher performance within a given die size and power envelope.
