AMD Ryzen 9 7900X vs Intel Xeon 634 Comparison

The AMD Ryzen 9 7900X and Intel Xeon 634 are both 12-core, 24-thread processors, but they target entirely different segments of the market. The Ryzen 9 7900X is a desktop part built on the Zen 4 architecture, while the Xeon 634 is a server/workstation chip using Granite Rapids. Despite the Xeon’s newer release date, the benchmark data reveals a complex picture where each processor dominates in specific workloads, making the choice heavily dependent on the intended use case.

FAQ

Q: Which processor has the higher average benchmark score?

A: The AMD Ryzen 9 7900X has an average benchmark score of 53,288, which is 0.6% higher than the Intel Xeon 634’s average of 52,974. Both processors sit at the 91st percentile compared to all CPUs.

Q: How do the two processors compare in single-threaded performance?

A: The Intel Xeon 634 wins the Cinebench R23 single-core test with a score of 4,510, which is 55.3% higher than the Ryzen 9 7900X’s score of 2,016.5. However, in Passmark’s single-thread test, the AMD part wins with 4,238 versus 3,567, an 18.8% advantage.

Q: Which processor is better for multi-threaded workloads?

A: The results are split. The Intel Xeon 634 wins Cinebench R23 multi-core with 31,950 versus 29,300 for AMD (an 8.3% advantage), but the AMD Ryzen 9 7900X wins Passmark’s multithread test with 51,406 versus 37,589, a 36.8% lead.

Q: What are the memory bandwidth capabilities of each processor?

A: The Intel Xeon 634 has a quad-channel memory bus and supports 204.8 GB/s of bandwidth. The AMD Ryzen 9 7900X has a dual-channel bus with 83.2 GB/s of bandwidth. Both support DDR5 memory and ECC.

Q: Do both processors have integrated graphics?

A: No. The AMD Ryzen 9 7900X includes Radeon Graphics, while the Intel Xeon 634 has no integrated graphics (N/A). This makes the AMD part more suitable for systems without a discrete GPU.

Q: Which processor has a higher boost clock?

A: The AMD Ryzen 9 7900X has a boost clock of 5.60 GHz, which is significantly higher than the Intel Xeon 634’s 4.60 GHz. The base clocks are also different, with AMD at 4.70 GHz and Intel at 2.70 GHz.

Architecture Differences

The two processors are built on different architectures with distinct design goals. The AMD Ryzen 9 7900X uses the Zen 4 architecture (codenamed Raphael) and is fabricated on a 5 nm process by TSMC. It features a chiplet design with a die size of 2x 71 mm² and contains 13,140 million transistors. The Intel Xeon 634 uses the Granite Rapids architecture, also on a 5 nm process, but fabricated by Intel. Its die size is much larger at 598 mm².

Cache configurations differ notably. The AMD part has 64 KB of L1 cache per core, 1 MB of L2 per core, and 64 MB of shared L3 cache. The Intel Xeon 634 has larger per-core caches: 112 KB of L1 and 2 MB of L2 per core, but a smaller 48 MB of shared L3. This means the Xeon has more fast per-core memory, while the Ryzen offers a larger pool of shared cache for all cores.

Memory architecture is a major differentiator. The Ryzen 9 7900X supports dual-channel DDR5 with 83.2 GB/s bandwidth. The Xeon 634 supports quad-channel DDR5 with 204.8 GB/s bandwidth, which is nearly 2.5 times the theoretical memory throughput. PCIe connectivity also differs: the AMD part provides Gen 5 with 24 lanes, while the Intel Xeon provides Gen 5 with 80 lanes. The Xeon is clearly designed for I/O-heavy server workloads, while the Ryzen targets consumer desktop use.

Other differences include the socket (AMD Socket AM5 for the Ryzen, Intel Socket 4710 for the Xeon) and the market segment (Desktop versus Server/Workstation). The AMD part has integrated Radeon Graphics, while the Xeon has none. Both processors have unlocked multipliers, support ECC memory, and have a TDP of 170W (AMD) and 150W (Intel). The release dates are far apart: the Ryzen 9 7900X launched on 2022-09-26, while the Xeon 634 launched on 2026-02-01.

Head-to-Head Benchmarks

The head-to-head data shows a decisive victory for the AMD Ryzen 9 7900X, which wins 12 of the 15 benchmark comparisons. The most lopsided win for AMD is in Passmark’s find prime numbers test, where it scores 388 versus 196 for the Intel Xeon 634, a 98% advantage. This indicates a massive lead in integer-heavy, latency-sensitive workloads.

In Passmark’s data encryption test, the Ryzen 9 7900X scores 37,263 versus 23,451 for the Xeon, a 58.9% lead. Similarly, random string sorting shows a 58.8% advantage for AMD (74,658 versus 47,016). These results suggest that the Ryzen’s higher clock speeds and architecture are better suited for these specific computational tasks.

The AMD part also wins Passmark integer math with 169,273 versus 117,664 (43.9% higher), data compression with 632,505 versus 477,924 (32.3% higher), and the overall multithread test with 51,406 versus 37,589 (36.8% higher). It also takes Passmark physics (3,060 versus 2,250, a 36% lead), extended instructions (47,619 versus 38,320, a 24.3% lead), and floating-point math (103,952 versus 93,564, an 11.1% lead).

However, the Intel Xeon 634 has its own victories. The most striking is in Cinebench R23 single-core, where it scores 4,510 versus 2,016.5 for AMD, a 55.3% advantage. It also wins Cinebench R15 single-core with 454 versus 323, a 28.9% lead. In Cinebench R23 multi-core, the Xeon takes the win with 31,950 versus 29,300, an 8.3% advantage. Notably, the Xeon does not have a Cinebench R15 multi-core win; that test goes to AMD with 4,820.5 versus 3,220, a 49.7% lead.

The win counts are 12 for AMD and 3 for Intel. The three Intel wins are all in Cinebench tests, while the AMD wins span both Cinebench and Passmark suites. This suggests that the Xeon’s architecture excels in the specific rendering workloads measured by Cinebench, particularly in single-threaded scenarios, but lags in the broader Passmark test suite.

The Verdict

The data paints a clear picture for most users. The AMD Ryzen 9 7900X is the better all-around processor, winning 12 of 15 head-to-head benchmarks and posting a higher average benchmark score. Its 36.8% lead in Passmark multithread and 43.9% lead in integer math make it the stronger choice for general productivity, content creation, and most compute-heavy tasks. The 98% advantage in prime number finding and 58.9% lead in encryption further solidify its position for scientific and cryptographic workloads.

The Intel Xeon 634 is not without merit, but its wins are concentrated in a narrow set of Cinebench tests. The 55.3% lead in Cinebench R23 single-core is substantial, and the 8.3% win in R23 multi-core shows it can handle rendering workloads well. However, for a desktop user, the Ryzen 9 7900X offers integrated graphics, a higher boost clock (5.60 GHz versus 4.60 GHz), and a larger shared L3 cache (64 MB versus 48 MB). The Xeon’s advantages are its quad-channel memory bandwidth (204.8 GB/s versus 83.2 GB/s) and 80 PCIe Gen 5 lanes versus 24, which make it a better fit for server environments with heavy I/O demands.

For a typical workstation or gaming PC, the AMD Ryzen 9 7900X is the clear recommendation. For a server requiring massive memory bandwidth and PCIe expansion, the Intel Xeon 634 has specific advantages that cannot be ignored, despite its lower benchmark scores in most other tests.

Where Each One Wins

The AMD Ryzen 9 7900X wins in the majority of computational benchmarks, making it the preferred choice for users who prioritize raw processing speed across diverse tasks. Its significant leads in Passmark data compression (32.3%), encryption (58.9%), and integer math (43.9%) indicate strong performance in file handling, security-related computations, and general programming workloads. The 98% win in prime number finding makes it ideal for mathematical and scientific simulations. With a higher base and boost clock, it is also better suited for latency-sensitive applications where single-thread speed matters, as evidenced by its 18.8% win in Passmark single-thread.

The Intel Xeon 634 wins in Cinebench R23 single-core and multi-core, as well as Cinebench R15 single-core. Its 55.3% lead in R23 single-core suggests that for pure rendering tasks that rely heavily on one core, the Xeon is superior. The 8.3% win in R23 multi-core shows it can also handle multi-threaded rendering workloads effectively. Its quad-channel memory bus and 80 PCIe lanes make it the clear winner for server applications requiring high memory throughput and extensive I/O expansion, such as database servers, virtualization hosts, and data-intensive workstations. The Xeon’s larger per-core L1 and L2 caches may also benefit workloads with high data locality.
