AMD Ryzen 5 PRO 5655G vs Intel Xeon 6337P Comparison

Head-to-Head Benchmarks

The Intel Xeon 6337P dominates the direct comparison, winning 14 of the 17 recorded head-to-head tests. The AMD Ryzen 5 PRO 5655G counters with 3 wins. The margin of Intel's victories is often substantial, not merely incremental.

In Cinebench testing, the Xeon 6337P holds a consistent edge across every version. In R15 multi-core, it scores 1893 against 1738, an 8.9% advantage. Single-core R15 shows 267 versus 245, a 9% lead. The pattern repeats in R20: 7888 versus 7244 for multi-core and 1113 versus 1022 for single-core, both at 8.9%. R23 mirrors this exactly: 18783 versus 17249 in multi-core and 2651 versus 2435 in single-core, again 8.9%. The consistency is notable; the Intel part holds the same relative advantage regardless of the Cinebench generation.

The Passmark suite tells a more complex story. The Xeon 6337P wins in raw compute throughput. In floating point math, it scores 53150 against the AMD's 38649, a 37.5% lead. Prime number finding shows a massive 120.4% difference: 108 versus 49. Physics simulation is the largest gap, with 1729 versus 686, a 152% advantage. Multithread performance is 15.5% ahead at 22098 versus 19129. Integer math is closer, but still 7% in favor of Intel at 72301 versus 67561. Random string sorting sees a modest 3.5% gain (26135 versus 25253).

Single-thread Passmark shows a commanding 26.6% lead for Intel: 4104 versus 3241. This is a larger gap than the Cinebench R15 single-core delta of 9%, suggesting the Xeon's peak clock advantage matters more in some single-threaded workloads.

The AMD Ryzen 5 PRO 5655G's wins are concentrated in specific memory and data-heavy tasks. Data compression shows 255608 versus 237373, a 7.1% win for AMD. Data encryption shows a 17.4% margin at 15253 versus 12604. Extended instructions (AVX/SSE style workloads) show 17944 versus 15366, a 14.4% win.

The pattern is clear: Intel wins in raw compute and physics simulation, AMD wins in data manipulation and cryptographic throughput.

Where Each One Wins

Pick the Intel Xeon 6337P for tasks that stress raw compute, high-frequency single-thread, and heavy floating point or integer math. Benchmark results indicate it is the stronger choice for rendering engines, physics simulation, prime number factoring, and any workload that scales with multithread core count. The 37.5% lead in floating point math and 152% lead in physics simulation are decisive. The 26.6% single-thread advantage also suggests better responsiveness in lightly threaded applications.

Pick the AMD Ryzen 5 PRO 5655G for data compression, encryption, and extended instruction workloads. The 17.4% lead in data encryption and 14.4% lead in extended instructions are the largest margins it holds. These wins come from the Zen 3 architecture's optimized cryptographic and vector instruction paths. Data compression at 7.1% is less decisive, but still a clear win.

The AMD part also has a lower 65 W TDP versus Intel's 80 W, which could translate to thermal headroom in dense systems, but no efficiency benchmarks are recorded. The Intel part's 80 W TDP with higher boost clock may require stronger cooling. The AMD's integrated Radeon Vega 7 graphics is a feature the Intel lacks entirely, making it the only one of the two with any display output capability.

Q: Does either CPU have integrated graphics?

A: The AMD Ryzen 5 PRO 5655G has a Radeon Vega 7 integrated GPU. The Intel Xeon 6337P has no integrated graphics.

Specification Differences

The two CPUs differ in several key specifications. The Intel Xeon 6337P has a base clock of 3.50 GHz and a boost clock of 5.30 GHz. The AMD Ryzen 5 PRO 5655G has a base clock of 3.90 GHz and a boost clock of 4.40 GHz. The Intel part boosts higher but starts lower.

The Intel Xeon has a TDP of 80 W, the AMD has a TDP of 65 W. The lower AMD TDP indicates a more energy-efficient design, but the Intel draws more power for a higher performance ceiling.

Memory support is identical: both are dual-channel. The Intel supports DDR4 and DDR5, the AMD supports DDR4 only. The Intel PCIe is Gen 5 with 16 lanes, the AMD is Gen 3 with 16 lanes.

Process nodes differ: the Intel is built on 10 nm at Intel foundry, while the AMD is on 7 nm at TSMC. The AMD has 10,700 million transistors on a 180 mm² die. The Intel has no listed transistor count, but its die is 163 mm².

The AMD has a 51.2 GB/s memory bandwidth. The Intel's memory bandwidth is not listed.

The Intel socket is Intel Socket 1700, the AMD is AMD Socket AM4. The Intel is a server/workstation part, the AMD is a desktop part. Both have ECC memory support.

The Intel launch MSRP is $375. The AMD has no recorded launch MSRP.

Architecture Differences

The Intel Xeon 6337P uses the Raptor Lake architecture (Raptor Lake-R codename), under the "Xeon 6 (Raptor Lake Refresh)" generation. It is a 10 nm Intel-fabricated design. Its cache is 80 KB L1 per core, 1.25 MB L2 per core, and 18 MB shared L3.

The AMD Ryzen 5 PRO 5655G uses the Zen 3 architecture, codename Cezanne, from the 5000 series Ryzen desktop line. It is a 7 nm TSMC design. Its cache is 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3.

The Intel has a larger L3 cache (18 MB versus 16 MB) and more than double the L2 per core (1.25 MB versus 512 KB). The Intel also has a higher boost clock by 0.90 GHz. These differences likely explain the Intel's large lead in floating point math and physics simulation.

The AMD has integrated Radeon Vega 7 graphics, which is absent on the Intel. The AMD is built on the older Zen 3 core but with a smaller process node (7 nm versus 10 nm). The Intel uses a newer architecture generation but a larger process node.

The AMD's data compression, encryption, and extended instruction wins suggest its Zen 3 core has more efficient crypto and data-path execution units, despite lower raw clock speed.

The Verdict

The Intel Xeon 6337P is the clearly superior performer in most workloads. It wins 14 of 17 benchmarks. Its advantages in multi-core rendering (8.9% in all Cinebench tests) and single-thread (26.6% in Passmark) make it the better choice for general compute, rendering, and simulation tasks. Its 17.5% lead in multithread and 37.5% lead in floating point math are decisive. If the workload is compute-heavy, this Intel part is the correct selection.

The AMD Ryzen 5 PRO 5655G is the better choice only for workloads that specifically benefit from its data compression and encryption strengths. With a 17.4% win in data encryption and a 14.4% win in extended instructions, it is the better option for cryptographic operations and certain vectorized data manipulation. Its lower 65 W TDP may also appeal to power constrained builds, but no performance-per-watt benchmarks are provided to verify efficiency.

The AMD also offers integrated graphics, which the Intel lacks entirely. That makes the AMD the only option for a system without a discrete GPU.

For a server or workstation that runs rendering, simulation, or heavy multithreaded tasks, the Intel Xeon 6337P is the stronger choice. For a desktop with integrated graphics, lighter tasks, and data-focused workloads, the AMD Ryzen 5 PRO 5655G is the better fit. The data does not suggest a general winner; it depends on the workload.
