AMD Ryzen 9 PRO 9955 vs Intel Xeon 6710E Comparison

Where Each One Wins

The Intel Xeon 6710E is the clear winner in heavily parallel workloads, taking 8 of the 11 head-to-head benchmark categories. Its most dominant results come in data compression (1230786 vs 684470, a 79.8% advantage) and data encryption (81850 vs 33754, a 142.5% advantage). These are workloads that scale with core count, and the Xeon's 64 cores versus the Ryzen's 12 cores creates an enormous throughput gap. The Xeon also wins in floating point math (219926 vs 121509, 81% ahead), integer math (302954 vs 182312, 66.2% ahead), physics (5000 vs 3332, 50.1% ahead), and random string sorting (151491 vs 71928, 110.6% ahead). Multithread performance favors the Xeon by 12.6% (61775 vs 54866), which is a narrower margin than the other parallel tests, suggesting the Ryzen's higher clock speeds partially compensate for its lower core count.

The AMD Ryzen 9 PRO 9955 wins in single-thread performance by a massive 58.5% margin (4597 vs 1910), and it also edges out the Xeon in the find prime numbers test (461 vs 451, a 2.2% advantage). The single-thread result is the headline story for AMD: the Ryzen's 5.40 GHz boost clock versus the Xeon's 3.20 GHz boost clock translates directly into a near-2.4x advantage in single-core throughput. The Ryzen also wins the extended instructions test? No, actually the Xeon wins that by 8.6% (59625 vs 54903). The Ryzen's wins are concentrated where latency and clock speed matter more than raw core count.

Architecture Differences

The architectural split here is stark. The Intel Xeon 6710E uses the Sierra Forest architecture on a 5 nm process from Intel's own foundry, built on the Xeon 6 (Sierra Forest-SP) generation. It packs 64 cores with 64 threads, meaning no simultaneous multithreading; each physical core handles one thread. The die size is 578 mm², and the cache hierarchy is unusual: 96 KB of L1 per core, 4 MB of L2 per module, and 96 MB of shared L3. Memory support is DDR5 across an eight-channel bus, delivering 358.4 GB/s of bandwidth. PCIe is Gen 5 with 88 lanes from the CPU. It has no integrated graphics and a TDP of 205 W. The socket is Intel Socket 4710, which is a server platform.

The AMD Ryzen 9 PRO 9955 uses the Granite Ridge codename with Zen 5 architecture on a 4 nm TSMC process. It is a 12-core, 24-thread part with simultaneous multithreading enabled. The transistor count is 16,630 million spread across a 2x 70.6 mm² die design. Cache is 80 KB L1 per core, 1 MB L2 per core, and 64 MB of shared L3. Memory is DDR5 on a dual-channel bus, giving 89.6 GB/s of bandwidth, roughly a quarter of the Xeon's. PCIe is Gen 5 with 24 lanes. It includes Radeon integrated graphics, which the Xeon lacks. The TDP is 120 W, and it uses AMD Socket AM5, making it compatible with mainstream desktop platforms. The release dates differ by over two years: the Xeon launched June 2024, while the Ryzen's release date is June 2026 in the database.

The core count difference is the defining factor: 64 cores versus 12 cores is a 5.3x ratio. The Ryzen compensates with much higher clocks (3.40 GHz base versus 2.40 GHz, 5.40 GHz boost versus 3.20 GHz) and a more modern 4 nm process versus 5 nm. The Xeon's eight-channel memory subsystem gives it enormous bandwidth for server workloads, while the Ryzen's dual-channel setup is typical for workstation desktops.

Head-to-Head Benchmarks

The largest single margin in the entire comparison is data encryption, where the Xeon scores 81850 versus the Ryzen's 33754, a 142.5% advantage. This reflects the Xeon's 64 cores chewing through cryptographic operations in parallel. Data compression shows a similar pattern at 79.8% ahead (1230786 vs 684470), and random string sorting is 110.6% ahead (151491 vs 71928). Floating point math is 81% ahead (219926 vs 121509), and integer math is 66.2% ahead (302954 vs 182312). Physics is 50.1% ahead (5000 vs 3332). Multithread is the closest Xeon win at 12.6% (61775 vs 54866), which is notable because this is the aggregate PassMark multithread score.

The Ryzen's wins are smaller in magnitude on the two tests it takes. The find prime numbers test is essentially a tie: 461 versus 451, a 2.2% edge for AMD. Single-thread performance is the outlier: 4597 versus 1910, a 58.5% advantage for the Ryzen. This is the single biggest delta in the Ryzen's favor, and it dwarfs the Xeon's margins in several parallel tests. The extended instructions test is a narrow Xeon win at 8.6% (59625 vs 54903), showing that the Ryzen's newer Zen 5 core is competitive on SIMD workloads despite having far fewer cores.

Looking at the overall averages, the Xeon's avgBenchmarkScore is 129930, while the Ryzen's is 110612. That is a 17.5% gap in overall average score. The Xeon sits in the 97th percentile of all CPUs, and the Ryzen also sits in the 97th percentile. The Xeon's nearest rivals include the AMD EPYC 9354 (2.5% behind), the AMD EPYC 9275F (2.4% ahead), the Intel Xeon 6730P (4.1% behind), and the AMD Ryzen Threadripper PRO 5975WX (4.6% behind). The Ryzen's nearest rivals are the Intel Xeon w7-2595X (1.8% behind), the AMD Ryzen 9 9850HX (3.9% behind), the Intel Xeon w7-3555 (4.2% behind), and the Intel Xeon 6527P (4% ahead).

The Verdict

The data points to two completely different use cases. The Intel Xeon 6710E is for workloads that can use every available core: data compression, encryption, large-scale math, and server-side processing. Its 64 cores and 358.4 GB/s memory bandwidth make it a server/workstation part through and through. The Ryzen 9 PRO 9955 is for single-thread-sensitive tasks, interactive workloads, and situations where clock speed matters more than core count. Its 5.40 GHz boost clock gives it a 58.5% single-thread advantage, which matters for applications that cannot parallelize well.

For a server rack running batch jobs, the Xeon's 79.8% compression lead and 142.5% encryption lead are decisive. For a workstation doing code compilation, rendering, or simulation where a single thread is the bottleneck, the Ryzen's single-thread score of 4597 versus 1910 makes it the obvious choice. The Ryzen also has integrated graphics, which the Xeon lacks entirely, so a build with the Ryzen does not require a discrete GPU for basic display output.

The Xeon's launch MSRP is $2749. The Ryzen has no launch MSRP recorded in the database. The Xeon's 205 W TDP versus the Ryzen's 120 W TDP also points to different platform requirements: the Xeon needs serious server cooling and power delivery, while the Ryzen can run in a standard AM5 desktop board. The Ryzen's dual-channel memory at 89.6 GB/s is a limitation for memory-bound server work, but for desktop workloads it is sufficient. The Xeon's eight-channel memory at 358.4 GB/s is overkill for most desktop use but essential for high-throughput server tasks.

Neither part is a universal winner. The Xeon wins the aggregate benchmark score (129930 vs 110612) and the majority of individual tests, but the Ryzen's single-thread dominance is a category that the Xeon cannot touch. If the workload is mixed, the Xeon's higher average score suggests it is the better all-around performer in parallel-heavy environments. If the workload is single-threaded, the Ryzen is the only rational choice.

The architectural differences are fundamental: the Xeon is a 64-core server chip with massive memory bandwidth and no graphics, while the Ryzen is a 12-core workstation chip with high clocks, integrated graphics, and a mainstream AM5 socket. The Ryzen's 4 nm TSMC process gives it a transistor density advantage (16,630 million transistors across a 2x 70.6 mm² design), while the Xeon's 578 mm² monolithic die is built on Intel's 5 nm process. The Ryzen's higher base and boost clocks (3.40/5.40 GHz versus 2.40/3.20 GHz) are the primary reason it wins single-thread tests despite having 52 fewer cores.
