AMD claims Epyc Genoa is twice as fast as Nvidia's Grace Superchip, Team Green counters with own benchmarks

[DragonSlayer101]

What just happened? Nvidia is the undisputed champion in the AI space with its GPU-based accelerators. However, AMD is now pushing back, claiming it's the new leader in the data center segment with its Grace CPU Superchip. The company released a series of benchmarks showing that its Epyc Genoa x86 CPUs are much faster than Nvidia's Arm-based Grace Superchip across several critical workloads.

According to AMD, its Epyc Milan CPUs already offer power-packed performance for data centers, but its 4th-gen Epyc Genoa and Bergamo platforms up the ante beyond the reach of the competition. To prove its point, the company showcased a series of benchmarks "proving" the 4th-gen Epyc processors have a massive advantage against Nvidia's Grace CPU in terms of performance and efficiency.

First, the 128-core Epyc 9754 and the 96-core Epyc 9654 can deliver more than twice the performance of the 144-core Grace Superchip in various workloads, including server-side Java, transactional databases, decision support systems, and web servers. General-purpose computing, in-memory analytics (Redis and Memcached), video encoding, and high-performance computing (HPL and Quantum ESPRESSO) saw similar gains.

Red Team also provided a power usage benchmark, showing the Epyc 9654 to be 2.27x more power-efficient than the Grace Superchip in dual-channel configurations. Meanwhile, the Epyc 9754 offers a 2.5x better performance-to-watt ratio in single-socket setups than the Grace CPU, while in dual-socket mode, its efficiency reportedly increases to 2.75x.

At first glance, the results might suggest that the Epyc chips are the best choice for demanding, power-hungry applications. However, it is important to note that these results are based on in-house testing, so take them with a pinch of salt until corroborated by our upcoming reviews.

Meanwhile, Nvidia released comparable benchmarks to combat AMD's claims, and as you'd imagine, they look very different from the results provided by Team Red. According to Nvidia, the Grace CPU Superchip is up to 2.4x faster on server-side performance and 3x faster on data center throughput than a dual-socket Epyc 9654. On average, the Grace CPU is 1.5-2.0x faster across multiple tests.

Either way, you're getting fake 2.5x the performance than you should expect in reality.

This is simple. Around half benchmarks AMD is showing are Spec or other very well known and very widely used benchmarks (Linpack for example). Nvidia on other hand uses some totally unknown random benchmarks.

No questions here. Nvidia cherrypicks, AMD does not. Also AMD does support 3TB memory whereas Nvidia only supports 480GB.

Nvidia is for niche market for specialized workloads whereas AMD is miles better for general purpose. No surprises here.

Yeah, like when Nvidia countered AMD's 16 bit performance claim using an 8 bit FP performance benchmark. I do not trust Nvidia to be honest.

Either way, you're getting fake 2.5x the performance than you should expect in reality.

The real issue that noone talks about is that many of these systems run at 100% power even if they aren't under 100% load, atleast at the hyper scale level.

So the reality is, it doesn't really matter how much better one chip is than the other. They start building the replacement before the new systems is being 100% utilized

Would not the corporate users of a certain size do their own testing. I suppose the problem is trying to lock in orders

Plus I saw in some over post maybe different type of chips, with AMD vs Intel , AMD support was offered much cheaper as they trusted their product.

So imagine I there are a lot of factors we don't see or consider

Who the hell wrote that headline!!!???
