Intel "P" Core:
-"performance" CPU core
-adds FP16 ML accel to AVX512
-claims 19% advantage over 11th Gen based on SPEC, Sysmark, Crossmark, PCMark, WebXPRT3, Geekbench
-Adds new "AMX" matrix engine for DL inference and training (?) claims 8X improvement on int8 (SR only)
$INTC
Thread Director does exactly what you would expect. It manages threads that:
-should go on P-core
-should go on E-core
-should move from P to E-core
If you recall early vers of Arm big.LITTLE had early issues with thread mgmt. Intel claims it's ahead of everyone on this. $INTC Intel Thread Director
Intel's Alder Lake (client) proc:
-spans ultra-portable (9W) to DT (125W)
-monolithic design, 3 pkg
-Up to 16C (8P/8E), 24T (16P/8E), 30MB cache
-DDR5, PCIe 5, WiFi6, Xe, TB4,
-Neither F or perf disclosed, but at min expect to be comp in notebook & <16T DT
-AI perf ?
$INTC Intel Alder Lake
Intel's Sapphire Rapids (datacenter) proc:
-focused on node *and* DC perf (smart positioning)
-distributed design (tiles + package, more like AMD), each thread can access all tile resource
-all P cores (see above for deets)
$INTC Sapphire Rapids
Like ICL, Sapphire Rapids has lots of acceleration, but better:
-Data streaming
-Crypto
-Compression, decompression
-AI
Now, how do you feed this beast?
$INTC
Sapphire Rapids is distributed design, many CPU cores, many acceleration blocks, how do you feed it and extract results?
-I/O: CXL 1.1, PCIe 5.0, UPI 2.0
-Cache: >100MB LLC, 8CH DDR5, Optane 300
-HBM2: 1TB/sec
$INTC
Intel didn't officially announce SR, so no deets on core count, frequencies, BUT Intel did share a few nuggets on accel (see above) plus:
-AI: AMX vs AVX FP32, BF16, INT8
-Microservices: SR vs CL vs ICL (cool!)
Net-net, right now expect really good perf in accel workloads.
$INTC
Intel announced "Mount Evans" IPU:
-ASIC-based (vs FPGA)
-best expl yet of IPU (or NV/Marvell DPU) & SmartNICs (bravo)
-ME IPU co-developed with "major CSP"; guessing Azure given FPGA work
-Compute Engine Arm Neoverse N1-based (surprise!)
Hard to gauge competitiveness.
$INTC

Now that @elonmusk owns @Twitter, I need to get a few things off my chest....
Sammy Hagar sucked in Van Halen and the band never really recovered. I went to the 1984 concert and David Lee Roth jumped off of the 20-foot set of speakers doing the splits. No comparison. And Sammy's restaurants suck.
Brussel sprouts, without all that sweet goo chefs apply, taste like used hockey socks would taste if enough green grew on them.

A real live press conference at #CES2022 woo hoo! @Qualcomm ImageImageImage
Qualcomm CEO @cristianoamon kicking off the presser thanking everyone for coming. Said he expected five people but over 75 showed up. Lol! Image
Appreciating @cristianoamon doing a strategic overlay on Qualcomm's vision. All about the edge. $QCOM ImageImage

Next up Intel #CES2022 presser. Tweeting from the press room LoL. How meta.
What's up @gregorymbryant? Image
We're going to be hearing about PCs, graphics and car announcents. #CES2022 Image

Intel held its Architecture Day on Tuesday. A trove of disclosures that I am still digesting. Stay tuned for analysis. One easy thing that I can say with certainty is that it will drive discrete GPU revenue and share. That’s not as easy to assess as you may think. $INTC
Gaming, Intel fields a performance desktop GPU "Arc" in Q1 that's up there with NVIDIA & AMD. Not at the top but close. NV & AMD will likely update so at worst case, as I have said for the past 4 years, Intel will have a very competitive mid-range, upper mid-range. TSMC N6. $INTC
Intel's gaming DGPU, Arc, has two features that are more similar to NVIDIA's arch than AMD's:
-Discrete ray tracing blocks
-Super-sampling driven by discrete AI blocks (XMX)

I think @awscloud has the clearest compute product positioning:
-"fastest"
-"largest"
-"most"
-"only"
-"best"
#reinvent
Graviton2 growing up a bit today with C6gn. Much higher performance workloads are possible like data analytics, nw appliances, load balancers, some HPC. #reinvent

Qualcomm's @cristianoamon starts off #SnapdragonSummit talking about:
-redefining premium experiences with #5G. As you would expect.
- Video. Gaming. XR. Life-saving.
- Many services "yet to be invented". Yup Image
Qualcomm a big R&D investor. $66B. While I don't like the comingling of "R" and "D" as its different, it's a huge number. Image
I wish @Verizon would match its #5G talk with what it actually does. I appreciate the vision and "what we're going to do" but disappointing so far. Speeds on mmWave are amazing, I want, but in so few places, it barely matters. #SnapdragonSummit
