Intel 12th gen (Alder Lake) processors: price and benchmarks, and DDR5 memory performance


Recommended Posts

It seems like Persian tech website sakhtafzarmag.com has posted pre-release information (almost a mini-review) with some very impressive benchmarks, pricing of the new Intel 12th gen processors (to be launched at the end of next October), as well as DDR5 performance.

 

Here are google translated links (in English) from the originals:

 

Some relevant quotes from their article(s):

 

"The new family seems to be a bit more expensive than the 11th generation in terms of pricing, but it will still be very valuable given the increased efficiency and other points. 

The blue company plans to offer the Core i9 12900K for $ 599, while the Core i9 12900 is priced at $ 509.

Next up is the Core i7 12700K, which will be labeled $ 429 to introduce itself as a more powerful model than the Ryzen 7 5800X, with 20 threads. The Core i7 12700 is also priced at $ 359.

Probably the best-selling chips in the Alder Lake family are the Core i5 series, so their price will be very important. The Core i5 12600K will cost $ 279, followed by the Core i5 12600 for $ 249. The Core i5 12400 model is priced at $ 203.

(note: prices are supposedly without taxes)

 

After discussing pricing, we come to Alder Lake benchmarks, which are not few in number. 
According to these benchmarks, Intel's 12th generation processors are much more powerful in terms of single-core processing than the previous generation, as well as the Ryzen 5000 chips. 
At the same time, their multi-core performance has improved tremendously, and now they are on par with AMD models or even better.

 

Of course, we still have to wait until the release of benchmarks and further reviews, but in any case, it seems that the blue giant is back in the game with full hands, and in the coming generations we can see a very hot competition between the two chip companies.
The twelfth generation of the Core series uses a new hybrid architecture with small (low-power) and large (powerful) cores combined. The series will replace the Rocket Lake S but will support PCI Express 5.0, the new LGA 1700 socket, as well as DDR5 memory.
It is unknown at this time what family Intel is measuring performance improvement on, but recent rumors have suggested that the Alder Lake S series will offer up to a 20% IPC improvement over Tiger Lake."

 

"This is not the first time we have seen DDR5 performance on Intel's next-generation platform, but this time the processor used has a much better frequency than the previous disclosure.

Although the memory uses 6400 MHz, the performance shows a huge improvement where the read speed is more than 90 Gbps. Since we are probably still seeing an engineering example and, of course, basic code, there is room for improvement. The performance numbers disclosed are apparently unknown to a Dell system with a model.

 

The processor used for the test is said to be a Core i5 12600K, and its single-core rating is shared on CPU-Z (785.6).

(note: same CPU-Z test with i9 10900K is 695.0 and Ryzen 9 5950X is 648.0, which means the mid-range i5 12600K is already 15~20% stronger than even the current high-range offferings, in single-score performance)

 

The not-so-interesting part of the story is the memory latency, which is still very high at 92.5ns, but the 40-40-40-85 timing of the DDR5 modules is also involved. 

At the moment, DDR5 does not look very exciting, and of course, like any new generation of memory, it's normal because the fastest memories of the previous generation usually perform better than the first few standards of the new generation. 
When manufacturers can bring DDR5 closer to maturity, we can see unique modules on the market."

Thanks a lot for the summary of the available information about Alder Lake S. 599$ (should be ~550€ i guess) for the 12900K seems to be acceptable (compared to the price of i.e. the 10900X / 10920X) imo, let's hope the prices for DDR5 RAM drop a little bit once the Mainboards and CPUs are available. Also i've read, that there will be DDR4 RAM Mainboards for Alder Lake S in the beginning. Don't know if this is true, but that would be a great option for people who don't want to spent the crazy price for DDR5 but still want to get Alder Lake. One thing to consider may be, that Alder Lake S requires Windows 11 wich is my only concern right now as i'm a bit worried about driver and (VR) game stability in the beginning. Still, the 12900K will be a instant purchase for me once it's available for order/pre-order.

Latency...92.5ns   oh man

 

I wanna see how that translates to DCS, VR and gaming in general.

 

We know how severe it struck first Ryzens.

Yeah.... indeed, it's one bit of info that left a sour note there specifically on DDR5.

 

I had to read it twice...  at first I thought "wow, 9.25ns latency so early is amazing!" only to find out I had misread.

Second time I thought it was a typo, as my calculations for 6400 CL40 are 12.5ns (the formula is CL/Frequency*2000) but, alas... 😐 

92.5ns value is the real value in that AIDA64 benchmark, surprisingly huge latency. And I mean HUGE latency for RAM. 

 

IIRC, RAM latency has been under 15 nanoseconds for at least the last 15 years, with what's considered good "mainstream" RAM memory being around 10 nanoseconds (on average) for this decade and half time period.

Some examples: 

  • DDR2 800 CL4 = 10.0ns
  • DDR3 1600 CL8 = 10.0ns
  • DDR4 3200 CL16 = 10.0ns

I'm not sure how this DDR5 latency issue will go in practice, but I have faith that mem manufacturers know what they're doing. 

I'm also confident that DDR5 6400 CL32 (etc) should be out sooner rather than later.

And there are a lot more settings for RAM, maybe that's where the magic happens with DDR5. Afterall, there's the big upside of read speeds at over 90 GB/s!

But at same time, yeah...... 😕 again, it feels really, really odd seeing over 9x higher(!) latency values of what has been considered "good" on RAM for such a long time.

You are mixing up two latencies.  The 92.5ns latency is between CPU<-->RAM if I got this right and the other value is RAM speed internally, how fast it can switch etc..

 

I am not super sure if that is totally correct, I can only say that i.e. my RAM at 3000-14-14-14-34 as of now has roughly 50ns latency on my Z370/8700k.

The same RAM kit on Z270 did the XMP 3600-16-16-16-36 and had round about 40ns latency.

The 1st gen Ryzens irc had values between 60ish-ns to 90ish-ns and were accused to be too slow for gaming.

 

It will be interesting to see how the first real world benchmarks of DDR5-AlderLake will perform. I expect a rather meh experience with the tip to "Wait for the 2nd gen if you can..." kinda statement.

Aaah ok, I got ya.

It is pure ignorance on my part as I never used AIDA64 (always used MaxMem instead) and interpreting it completely wrong as just basic latency calculation from RAM timings. 

Yes, common DDR4 kits (such as 3200 CL16) go around 55ns, and now that mention of 92.5ns value of such DDR5 mem makes more sense (and still not good!).
