Intel Rocket Lake-S Platform Detailed, Features PCIe 4.0 and Xe Graphics
Intel's upcoming Rocket Lake-S desktop platform is expected to arrive sometime later this year, however, we didn't have any concrete details on what will it bring. Thanks to the exclusive information obtained by VideoCardz'es sources at Intel, there are some more details regarding the RKL-S platform. To start, the RKL-S platform is based on a 500-series chipset. This is an iteration of the upcoming 400-series chipset, and it features many platform improvements. The 500-series chipset based motherboards will supposedly have an LGA 1200 socket, which is an improvement in pin count compared to LGA 1151 socket found on 300 series chipset.
The main improvement is the CPU core itself, which is supposedly a 14 nm adaptation of Tiger Lake-U based on Willow Cove core. This design is representing a backport of IP to an older manufacturing node, which results in bigger die space due to larger node used. When it comes to the platform improvements, it will support the long-awaited PCIe 4.0 connection already present on competing platforms from AMD. It will enable much faster SSD speeds as there are already PCIe 4.0 NVMe devices that run at 7 GB/s speeds. With RKL-S, there will be 20 PCIe 4.0 lanes present, where four would go to the NVMe SSD and 16 would go to the PCIe slots from GPUs. Another interesting feature of the RKL-S is the addition of Xe graphics found on the CPU die, meant as iGPU. Supposedly based on Gen12 graphics, it will bring support for HDMI 2.0b and DisplayPort 1.4a connectors.
Some things like Direct Media Interface (DMI) will double the bandwidth and now there will be eight links present, compared to four of the previous platforms. Announced at CES 2020, ThunderBolt 4 will also be present along with USB 3.2 20G. Additionally, Intel Software Guard Extensions (SGX) have been removed to improve the security of the platform, as the SGX has proved to be quite vulnerable to many kinds of attacks and exploits. There are some updated media encoding standards as well, like 12-bit AV1/HEVC and E2E compression.

OMG, you're on fire man. And I'm called a fanboy around here...
Can you point me to the source of these graphs?
I would like to meet the person who got more fps from GT2 than from GT3e.
"Creators unleashed" slide figures don't make much sense as well - even just comparing Intel CPUs.

www.notebookcheck.net/Intel-Core-i7-1065G7-Laptop-Processor-Ice-Lake.423851.0.html
Also, how is this relevant to the topic, isn't the topic about upcoming desktop chips?
Also, I don't see why Ice Lake is "terrible". It is a really good mobile x86 (e.g. low-power) chip. Intel just failed at bringing it to desktop, that's all.
If Rocket Lake gets released in maximum 8-core flavour, imagine how competitive it will be against Vermeer with at least 16 cores, potentially even more.
Would stopping the guessing and speculation be an option for you?
Ryzen 7 4800U at 15W achieves 3300 points in Cinebench 20.
Core i7-1065G7 at 15W achieves 1650 points in Cinebench 20.
What is the performance per watt difference according to you?
Also, let's compare Ryzen 7 3700X at 65W - 22792 points in PassMark www.cpubenchmark.net/cpu.php?cpu=AMD+Ryzen+7+3700X&id=3485
Core i7-9700K at 65W - 14554 points in PassMark www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-9700+@+3.00GHz&id=3477
Difference in performance per watt 57%.
Ryzen 7 3700X at 65W - 4760 points in CB R20 www.guru3d.com/articles-pages/amd-ryzen-7-3700x-ryzen-9-3900x-review,10.html
Core i7-9700K at 65W - 3656 points in CB R20 www.cpu-monkey.com/en/cpu-intel_core_i7_9700k-888
Difference in performance per watt 30%.
Because if you do, I'll try to be patient and helpful. If not, I'll keep having fun.
Clearly, you read a lot of benchmark results (more or less credible...). I hope you're using that PC for something else. :)
BTW, I'm waiting for source of those earlier graphs. Honestly.There is no N10 process.
So?
Among the more trustworthy leaks I've seen: NoteBookCheck apparently failed to exclude their test data for the Lenovo Yoga Slim 7 with the Ryzen 7 4800U from their searchable results database, meaning it could be added to comparsion tables in any laptop review. Sadly the person screenshoting the results didn't add an Ice Lake machine to all of the comparison graphs, so some of them are rather AMD-heavy. Interesting nonetheless. Some sources report that laptop as configured to 25W, while others say it's a 15W but with an extended 25W turbo window when thermals allow for it - I guess we'll see which it is when the NBC review is published.
I've found this:
www.techspot.com/news/84400-amd-details-ryzen-mobile-4000-performance-architecture-features.html
So the slides are from something called "AMD Tech Day".
So I tried to get that presentation from AMD's IR site, but it wasn't added:
ir.amd.com/events-and-presentations/past-events
Nothing here either:
ir.amd.com/search?query=tech+day&op=Search
Basically, the figures are weird and unrealistic - for example with GT3e being beaten in games by GT2, which has roughly half of the cores and performance.
And the results aren't coherent between games, so where different laptops used or what? Is this cherry-picked from multiple runs?
Bottom of the slide:
"See endnotes RM3-227. Results my vary."
Yes. "MY":

In Audio LAME, the 8-thread Ryzen 7 4700U is faster than the 16-thread Ryzen 7 4800U.
How do you explain it ?
I'm contesting these slides. You're using them to support your theories.
www.cpu-monkey.com/en/cpu-amd_ryzen_7_4800u-1142
www.cpu-monkey.com/en/cpu-intel_core_i7_1065g7-933
Both are with configurable up and down TDPs of 25-watt and 12-watt.
i7-1065G7 is a bad CPU. Period.
