GoKawiilAlthough the industry has largely learned to move out of the way when the big green giant that is Nvidia steps into the room, one AMD executive said he was “very happy” to see Nvidia publish SPEC CPU 2026 benchmarks for its Vera CPU ahead of the Advancing AI 2026 event. AMD used the configuration in Nvidia’s white paper as a basis to run SPEC on its new Zen 6 ‘Venice’ CPUs, offering what it calls an “apples-to-apples” comparison between the two chips.
“We are very happy that Nvidia published their Vera performance [numbers],” said AMD’s Ravi Kuppuswany, corporate VP of compute and enterprise solutions. “We were actually being a little conservative. I actually thought we were beating them by smaller numbers than what I have here… we thought we’d have at least a 10% advantage. What we’re finding is… we have 20% advantage, and we have not even finished completely tuning.”

Kuppuswany’s comments overlaid the slide you can see above, claiming 2.2x higher throughput with Venice compared to Vera, and 1.2x faster per-core performance. AMD has certainly stacked the deck in its favor here (as did Nvidia when it first published its Vera results), so let’s go through what this chart actually says.

As a quick aside, you’ll see “estimated” in the images above and below. These numbers aren’t guesses (they’re based on real runs), but SPEC maintains strict reporting guidelines for “official” runs. And because these runs aren’t reported to SPEC and therefore haven’t gained official status, they must come with the “estimated” disclaimer.
The throughput number is the easiest one to clarify. AMD compared its 256-core, 600W Epyc 9996 against the 88-core Vera, both in a 2P configuration. Yes, the CPU with more than twice the number of threads and an extra 150W stacked on top of its TDP has significantly higher throughput, as it should.
AMD would argue that it’s a fair comparison given that Nvidia is only offering Vera as a single, 88-core SKU. But the reality remains that the throughput comparison is one Vera could never win, and Nvidia would ( and has ) argued that it’s not trying to win in a race against the 256-core Venice. It’s building a single CPU for a single purpose.
The more interesting and consequential number here is the per-core performance. SPECrate_int is a throughput benchmark. A typical run loads all threads with a copy of an application and measures how much work gets done within a set amount of time. SPECspeed is the inverse of that, looking at a single application and how quickly it can run. AMD arrived at the numbers above by taking the overall SPECrate_int score and dividing it by the number of cores.
