Intel Core i9-7920X 12C/24T cache size and base clock revealed

[HEXUS]

This $1,189 CPU's base clock is just 2.9GHz, shows the latest official Intel price list.

+$200 for an extra 1.8Ghz of theoretical speed increase (core count x clock speed), extra heat output and energy usage.

Or to put it another way a maximum performance boost of 5.4% under theoretical optimum conditions, and probably worse most of the time due to lack of multithreaded optimisation.

One for Intel e-peen fanboys.

I will humbly wait to see the comparative benchmarks because AMD EPYC and the Intel Xeon-SP processors going head to head were pretty close to the balls with each other in low-mid/high, it was only in high/extreme that AMD slipped off the table (which isn't their target market). So if these are just *cough* re-branded Xeons then Threadripper is in a very good position, clock for clock the Instruction Count is looking very good and the fact that Threadripper can have a higher clock consistently across all cores is very promising indeed.

We shall see but these are very tumultous times.

Edit: However I am very interested in how the L3 cache sizes up between the two architectures, it's quite interesting!

Priced out of reach for most people in my opinion

I'll wait six years as I'll then be able to grab one at a great price.

I was worried that threadripper would struggle vs monolithic 12-18 core X299, but if this is the clock speed penalty for a large chip (or for cheapening out on the TIM) then AMD is in a pretty good position.

Hahaha it is running at a base clock of 2.9GHz becoz it will boil itself. The community has woken up no more i-Sheep, 90% who are willing to buy will wait for Threadripper launch in the next 2 weeks and possibly save $300 in cash. AMD 'glued' processors are causing intel to re-budge xeons with the i9 sticker.

...and possibly save $300 in cash.

And that's no counting in the peripheral costs!

These are using different chips to the other SKL-X CPUs IIRC,so are probably quite large.

I was already thinking threadripper was the way to go if I was to upgrade and if this info is anything to go by I'd say that it's actually the only way to go.

It seems that for intel to get the 'headline' core counts they're having to drop the performance of the cores to compensate for the heat etc.

Tbh, I wonder if their 18c36t sku will have an around 2Ghz clock, because if they can't get a base clock above 3GHz for a 12c24t then I'm really not holding much hope for their higher core count skus

[3dcandy]

Actually shows that Intel are running scared....
But many people won't worry about the baseclocks as they'll just enjoy the thread performance

Sounds like high core count Xeons behave differently: https://semiaccurate.com/2017/07/19/...diverged-core/

Not that I am even trying to keep track of the re-badging in Intel land these days given the cost level it happens at.

[elites2012]

its extremely sad at these intel prices. their is NO reason the prices should be this high.

People will pay it, that is an excellent reason.

[CAT-THE-FIFTH]

The reason the cost is high is the massive chip used.
