AMD Ryzen 9 5900HX vs Intel Xeon 6333P Comparison

Where Each One Wins

The head-to-head benchmark data splits this comparison into two clearly defined territories. The AMD Ryzen 9 5900HX takes the majority of wins, capturing 9 of the 15 recorded tests, while the Intel Xeon 6333P secures 6. The AMD part dominates in throughput-heavy and data-processing workloads, while the Intel chip claims victory in specific single-threaded and mathematically intensive tasks.

Looking at the AMD wins, the pattern is consistent: it leads in all three PassMark data manipulation tests. Data compression shows the largest gap, with AMD at 287793 against Intel's 199886, a 30.5% deficit. Data encryption follows at 18188 versus 11025, a 39.4% margin. Extended instructions also favor AMD, 19488 to 13039, a 33.1% edge. Integer math is another decisive AMD win at 86735 versus 61458, a 29.1% lead. Floating point math goes to AMD as well, though narrower at 47556 versus 43801, only 7.9% ahead. Random string sorting also favors AMD, 30042 to 22010, a 26.7% gap. The PassMark multithread score lands with AMD at 22326 against 18374, a 17.7% advantage. In Cinebench R15, AMD wins both multi-core (2106 vs 1574, a 25.3% margin) and single-core (240 vs 222, a 7.5% lead).

The Intel Xeon 6333P claims the remaining 6 wins, and they are concentrated in areas where its architecture appears to excel. The biggest Intel victory comes in Cinebench R23 single-core: 2204 versus 1488, a massive 48.1% lead. Multi-core R23 also goes to Intel at 15617 versus 12845, a 21.6% advantage. PassMark physics shows Intel at 1320 versus 909, a 45.2% margin. The find prime numbers test is also an Intel win, 83 versus 53, a 56.6% result. Finally, PassMark single-thread reports Intel at 3450 versus 3178, an 8.6% edge.

This split suggests a clear use-case distinction. For workloads that stress many threads and memory operations, AMD dominates. For tasks that depend on raw per-core speed or specific integer/prime calculations, Intel leads.

Architecture Differences

The two chips come from very different design families. The Intel Xeon 6333P is based on the Raptor Lake architecture, specifically Raptor Lake-R, and it is a 10 nm part fabricated by Intel. It uses an Intel Socket 1700 package and is targeted at the server and workstation segment. The chip has 6 cores and 12 threads, with a base clock of 3.10 GHz and a boost clock of 5.20 GHz. Its cache layout includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3. The TDP is 65 watts, and the processor supports both DDR4 and DDR5 memory on a dual-channel bus. It also carries ECC memory support, a feature absent from the AMD part. The Xeon uses PCIe Gen 5 with 16 CPU lanes, and it has no integrated graphics. The recorded die size is 163 mm².

The AMD Ryzen 9 5900HX is built on the Zen 3 architecture, codenamed Cezanne, and uses TSMC's 7nm process. It is a mobile-processor with an AMD Socket FP6 package. It has 8 cores and 16 threads, with a base clock of 3.30 GHz and a boost clock of 4.60 GHz. The cache is 64 KB L1 per core, 512 KB L2 per core, and 16 MB of shared L3. The TDP is lower at 45 watts. Memory support is DDR4 only, with a dual-channel bus and a recorded memory bandwidth of 68.3 GB/s. It does not support ECC memory. The PCIe is limited to Gen 3. The integrated graphics is Radeon Vega 8, which the Intel part lacks. The transistor count is listed as 10,700 million, and the die size is 180 mm². The multiplier is unlocked on the AMD part, while the Intel is locked.

The architectural difference is stark: Intel uses a newer desktop-derived design with fewer cores but a much higher boost clock, while AMD uses an older, smaller-node design with more cores and lower clocks. The Intel supports ECC and newer PCIe, while the AMD offers integrated graphics and a lower TDP.

The Verdict

The data suggests these are not interchangeable for a typical buyer. The Intel Xeon 6333P, with its 6 cores and 12 threads, is best suited for single-threaded workloads and tasks that rely on high per-core frequency. Its Cinebench R23 single-core score of 2204 is a standout, and it also leads in PassMark single-thread at 3450. The prime number test and physics test also indicate strong integer and scalar performance. This makes it a plausible choice for workstation roles where per-core speed is critical.

The AMD Ryzen 9 5900HX, with 8 cores and 16 threads, is the better option for multi-threaded and memory-heavy tasks. It wins all three PassMark data tests (compression, encryption, extended instructions) by margins of 30% to 39%, and also leads in integer math and multithread performance. It also holds a 25.3% lead in Cinebench R15 multi-core, which is likely due to its higher core count. The AMD also has integrated graphics and a lower TDP, making it more suitable for mobile systems.

The average benchmark score in the database gives the AMD a slight edge overall: 24,822 versus 23,823. The percentile ranking is also close, with the AMD at 77 and the Intel at 76. The nearest rivals confirm this: the AMD is within 0.5% of the Intel Core 5 210H and Core i7-13620H, while the Intel is within 1.1% of the Ryzen 5 8600G. In short, pick Intel for raw single-core speed and ECC support, and AMD for multi-thread throughput and data processing.

Head-to-Head Benchmarks

The largest Intel win is a clear one. In Cinebench R23 single-core, the Intel scores 2204 against the AMD's 1488, a 48.1% lead. That is a big margin for a single-core workload and reflects the Intel's 5.20 GHz boost clock versus the AMD's 4.60 GHz. The multi-core R23 test also goes to Intel, 15617 to 12845, a 21.6% gain, which is interesting because the AMD has more cores. The Intel's higher clock appears to compensate in this test.

The Intel also dominates the PassMark physics test, 1320 vs 909, a 45.2% lead. This test likely responds to the Intel's strong integer math. The prime number test shows a similar pattern, at 83 to 53, a 56.6% edge. The PassMark single-thread test is a closer Intel win, 3450 vs 3178, an 8.6% margin.

The AMD's biggest wins are in data compression and encryption. In data compression, AMD scores 287793 against Intel's 199886, a 30.5% deficit for Intel. Encryption shows a 39.4% gap, with AMD at 18188 and Intel at 11025. Extended instructions also go to AMD, 19488 vs 13039, a 33.1% difference. Integer math is another strong AMD win, 86735 vs 61458, a 29.1% margin.

Floating-point math is a closer AMD win, 47556 vs 43801, only 7.9% ahead. Random string sorting sees AMD at 30042 vs 22010, a 26.7% edge. PassMark multithread gives AMD 22326 vs 18374, a 17.7% lead. The 3DMark tests are not in the head-to-head list, but the AMD has its own data showing 6490 in 16-thread, 1720 in 2-thread, 3285 in 4-thread, 5406 in 8-thread, and 6487 in max-thread. These are not compared directly here, but they show the AMD's scaling pattern.

The summary of the head-to-head is that the Intel wins every test that is primarily single-thread or integer-prime, while the AMD wins every test that is data-intensive or multi-thread. The AMD's 9 wins against Intel's 6 confirm its broader strengths, but the Intel's single-core dominance is a critical differentiator for certain workloads.
