Intel also supports a gen3 “Crow Pass” Optane on SPR, but it looks like future memory expansion could be via the pcie/CXL in concert with IPUs. Emerald Rapids is rumored to have some extension to the SPR CXL, and Granite Rapids and Sierra Forest are rumored to implement the full CXL 2.0. Sierra Forest is coming in 1H 2024, according to Intel in their last earnings call.

Putting aside the imminent release of the Genoa-X parts, it’s worth noting that Intel didn’t use AMD’s best 32 core chip in this comparison. The 9374F clocks nearly 20% faster than the 9354 featured in these tests. Most likely Intel’s performance gap would shrink but their efficiency gap would grow.

Great benchmarks and analysis! It seems that Sapphire Rapids is a proper contender for upcoming ’bouts of the Battle Royale … can’t wait to see Aurora slide into its glass slippers and moozy its gluteus maximuses on over to the Ballroom Blitz! El Capitan’s swashbuckling MI300A (with HBM if I remember) should retake the crown of this pirate HPC tango contest soon after Aurora, but the Xeons should still provide a nice break in metaphors and plotlines.

Also, it seems that Xeon Max with AMX and HBM could compete well with Fugaku on HPCG (better oomph expected as the article astutely notes!) — something to watch …

“…because BF16 data types were not yet supported in the AMD Genoa AMD ZenDNN software stack yet”

Intel has bf16 support in the AMX matrix operations. AMD’s avx512 bf16 performance should still trail. Intel has presented comparisons of AMX with their own avx512 bf16 performance that you could use as a reference.

Initial Sapphire Rapids and Genoa supply stats run to date as of 6.3.23;

Sapphire Rapids;

MAX = 0.00069% at $1K AWP currently $11590 only 9480 5 core shows in channel
Platinum = 10.3% at $8811.28
Gold = 41.4% at $1766.56 subject XCL gold SKUs return to secondary + 15% prior 8 weeks
Silver = 14.2% at $692.16
W34xx_ = 2.2% at $2950.27
W24xx_ = 31.6%* at 1096.63

Full line $1K AWP = $2198.97

*Note channel secondary shows increasing trade-in W32xx_ @ and < 16C and W22xx all SKUs + 112% and 31% respectively prior eight weeks. Tim, outside servers themselves, how about a report on SR accelerated development system options. Specific W is it a box? Are they cards?

SR by core grade run to date;

60C = 1.14%
56 = 2.34%
52 = 0.54%
48 = 4.68%
44 = 0%
40 = 0%
36 = 1.40%
32 = 10.97%

16 = 12.58%
12 = 13.58%
10 = 7.63%
8 = 8.7%
6 = 7.63%

Note; Strategically Intel fills SI channel with 12 to 24 core Gold 55xx and Silver 44xx equals 33.2% of total volume run to date.

48 = 5.61%
32 = 20.62%
24 = 6.8%
16 = 10.66%

Strategically AMD continues to focus on top core count product @ 64C +

2P = 72.3%
1P = 17.6%
X = tbd
F = 1%

$1K AWP = $7143.43
