Recently we covered the AMD EPYC Bergamo Launch live. This is AMD’s cloud-native processor with up to 128 cores. We expect these to be popular CPUs. At the same time, because we were focused on live coverage, we never published the very short SKU list, so we have a quick piece to do so now.
AMD EPYC Bergamo Launch SKUs
As a short reminder, the 4th Gen AMD EPYC 97X4 series is the AMD EPYC “Bergamo” line of CPUs with either 128 cores or 112 cores.
AMD is actually lowering the maximum CCDs per socket count to eight from twelve on the standard Genoa parts. Still, those CCDs now have 16 cores each rather than 8.
Allowing AMD to do this shrink is a slightly cut-down Zen 4c core that takes up less area on the die than a standard Zen 4 core.
While most of the core is the same between the Zen 4 and Zen 4c, AMD has halved the amount of L3 cache per core to 2MB from 4MB, and that is what generates the huge area savings.
Putting that into the SKU stack, AMD only has three SKUs, two 128 core parts, one 112 core part.
The AMD EPYC 9754 is the flagship part with 128 cores and 256 threads at $11,900. That is likely the best CPU if you use increments of two vCPUs in your VMs. For those who do not want or do not need SMT, there is the 128-core and 128-thread AMD EPYC 9754S at $10,200. The AMD EPYC 9734 is the 112-core part at $9,600. AMD does not have SKUs below the 112-core figure because that starts to get into the 96-core Genoa line.
Final Words
While there are only three SKUs, these are likely to be the most exciting EPYC CPUs in this generation. These bring an enormous number of cores to AMD sockets more than doubling Intel’s top-bin SKUs in terms of density. This is the first time it has happened since 2019’s AMD EPYC 7002 “Rome” launch. Also notable is that AMD’s launch brings it to higher thread counts than the Ampere AmpereOne, albeit the AmpereOne has more cores. Intel for its part is planning a 144-core Intel Sierra Forest with its new and improved E-cores in the first half of 2024. Stay tuned until we can bring you more on the AMD EPYC “Bergamo” series, but the performance of these parts is very good.

This chip was made for running many VMs in parallel so I would love to see a comparison for webserver and DB tasks similar to this:
Bergamo 16x 8-core VMs
Genoa 16x 6-core VMs
Milan 8x 8cores VMs
For my use-case I’m defenitely not buying for 10k now that I can get a 7713 for 2k (with cheaper DDR4) but once the prices come down this could be an interesting CPU.
“While most of the core is the same between the Zen 4 and Zen 4c, AMD has halved the amount of L3 cache per core to 2MB from 4MB, and that is what generates the huge area savings.”
Again this is incorrect, AMD did not include L3 when detailing how they had achieved the 35% reduction in Zen4c over Zen4. Denser design libraries reflecting reduced frequency targets and the removal of the 3D cache through-silicon via’s (TSVs) contributed the bulk of the die size reduction. Describing Zen 4c as just a Zen4 with less L3 cache is just not accurate.
Very nice.
@Lasertoe I am not sure where you could get them for 2K, but generally speaking they should be $3.5K or half the price of RSP in this case for 7713 it was 7K. So I expect the same for 9754 to be around for $5.5K.
In mainland europe (Germany, Austria, Poland and so on) they are about 2250 Euro including taxes right now from big retailers. Were even cheaper last week (probably USD/EUR changes).
Prices have been very low for 7713 since february. The 7713 is also much cheaper than the 7713P…
I don’t want to advertise a store so I link a price comparison site:
