AMD Ryzen 7 8840U vs Intel Xeon 6333P Comparison

The AMD Ryzen 7 8840U and Intel Xeon 6333P land in the same performance tier despite their contrasting designs. Both processors hold a 76th percentile ranking among all CPUs, and their average benchmark scores sit within 0.7% of each other—the Ryzen 7 8840U averages 23,982, while the Xeon 6333P averages 23,823. The data reveals a split personality: the AMD chip dominates most workload categories with double-digit margins, yet the Intel part strikes back decisively in Cinebench R23 and single-threaded physics tests. This is not a straightforward "winner" scenario but a question of which benchmark suite matters more for a given use case.

FAQ

Q: How close are these two processors in overall performance?

A: The average benchmark scores are nearly identical. The AMD Ryzen 7 8840U scores 23,982, while the Intel Xeon 6333P scores 23,823, a difference of just 0.7%. Both CPUs also share the same 76th percentile ranking against all CPUs.

Q: Which processor wins the most head-to-head benchmark comparisons?

A: The AMD Ryzen 7 8840U wins 11 of the 15 head-to-head benchmark comparisons. The Intel Xeon 6333P wins 4 comparisons, but those wins include the heavily weighted Cinebench R23 multicore and singlecore tests.

Q: What is the biggest performance gap between the two in any single test?

A: The largest margin is in PassMark random string sorting, where the AMD Ryzen 7 8840U leads by 46.1%. The AMD chip scores 32,158 against the Xeon's 22,010. Data encryption is close behind with a 45.8% advantage for AMD.

Q: Does the Intel Xeon 6333P have any clear advantages in the benchmark data?

A: Yes, particularly in Cinebench R23. The Xeon 6333P leads by 22.7% in singlecore (2,204 vs 1,703) and by 16.9% in multicore (15,617 vs 12,972). It also wins PassMark physics by 10.9% and find prime numbers by 6%.

Q: How does the AMD Ryzen 7 8840U compare in Cinebench R15?

A: The AMD chip wins both R15 tests. It scores 2,024 in multicore versus 1,574 for Intel (a 28.6% lead), and 266 in singlecore versus 222 (a 19.8% lead). This contrasts sharply with the R23 results, where Intel leads.

Q: Which processor has the higher boost clock?

A: The Intel Xeon 6333P has a slightly higher boost clock of 5.20 GHz, compared to 5.10 GHz for the AMD Ryzen 7 8840U. However, the AMD chip has a higher base clock of 3.30 GHz versus 3.10 GHz for Intel.

The Verdict

The benchmark data points to a clear split based on workload type. For general productivity, data processing, and multi-threaded integer work, the AMD Ryzen 7 8840U is the stronger pick. It wins PassMark multithread by 27.1%, integer math by 39.5%, and data compression by 33.8%. These are substantial margins that indicate real-world responsiveness in typical desktop tasks.

However, for users running rendering workloads similar to Cinebench R23, the Intel Xeon 6333P is the better choice. Its 16.9% multicore lead and 22.7% singlecore lead in that specific benchmark are significant. The Xeon also wins the PassMark physics test, which suggests strength in simulation or physics-based applications.

The choice depends on whether the workload aligns with AMD's broad wins or Intel's specific strengths. The data does not support a universal recommendation. If the priority is the widest range of performance wins, particularly in memory-heavy or encryption tasks, the AMD Ryzen 7 8840U is the pick. If the priority is raw rendering throughput as measured by Cinebench R23, the Intel Xeon 6333P is the pick.

Head-to-Head Benchmarks

The AMD Ryzen 7 8840U dominates the PassMark suite. In integer math, it scores 85,740 against 61,458, a 39.5% advantage. Data encryption shows an even larger gap: 16,072 versus 11,025, a 45.8% lead. Extended instructions follow a similar pattern, with AMD ahead by 43.1% (18,654 vs 13,039). Random string sorting produces the largest delta of the entire comparison at 46.1% (32,158 vs 22,010). Data compression is also lopsided, with AMD scoring 267,525 against 199,886, a 33.8% win.

Floating point math is closer but still favors AMD. The Ryzen 7 8840U scores 48,820, while the Xeon 6333P manages 43,801—an 11.5% margin. The PassMark multithread test shows AMD ahead by 27.1%, with scores of 23,346 and 18,374 respectively. Even in single-thread PassMark, AMD holds a slim 2.7% edge (3,543 vs 3,450). The Cinebench R15 results also favor AMD substantially: a 28.6% multicore win (2,024 vs 1,574) and a 19.8% singlecore win (266 vs 222).

The Intel Xeon 6333P counters in Cinebench R23 with authority. The multicore score of 15,617 beats AMD's 12,972 by 16.9%. The singlecore gap is even wider at 22.7%, with Intel scoring 2,204 against AMD's 1,703. PassMark physics also goes to Intel, 1,320 versus 1,176, a 10.9% margin. The find prime numbers test is the closest contest, with Intel winning 83 to 78, a 6% difference.

Specification Differences

The core and thread counts differ significantly. The AMD Ryzen 7 8840U has 8 cores and 16 threads, while the Intel Xeon 6333P has 6 cores and 12 threads. Clock speeds are comparable but not identical: AMD has a 3.30 GHz base clock and 5.10 GHz boost, while Intel has a 3.10 GHz base and 5.20 GHz boost. Thermal design power is a major differentiator—AMD is rated at 28W, Intel at 65W.

Memory support diverges as well. The AMD chip supports DDR5 only, while the Intel part supports both DDR4 and DDR5. AMD lists a memory bandwidth of 89.6 GB/s; Intel does not provide a bandwidth figure. ECC memory support is exclusive to the Intel Xeon 6333P. PCIe connectivity differs: AMD offers Gen 4 with 20 lanes, while Intel offers Gen 5 with 16 lanes.

The cache structures are not identical. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3. Integrated graphics are present on the AMD chip (Radeon 780M) but absent on the Intel part. The market segments also differ: AMD is a mobile processor, while Intel is aimed at server/workstation use.

Architecture Differences

The manufacturing process sets these two apart fundamentally. The AMD Ryzen 7 8840U is built on a 4 nm node by TSMC, while the Intel Xeon 6333P uses a 10 nm node from Intel's own foundry. The AMD chip uses the Zen 4 architecture with the Hawk Point codename, part of the 8000 series. The Intel part uses Raptor Lake architecture with the Raptor Lake-R codename, listed as Xeon 6 generation.

Transistor counts differ, with AMD listing 25,000 million transistors on a 178 mm² die. Intel does not provide a transistor count but lists a die size of 163 mm². These architectural differences likely explain the performance profile: AMD's denser 4 nm process enables higher efficiency at lower TDP (28W vs 65W), while Intel's larger process node still achieves competitive or better results in specific rendering tests.

The socket types are incompatible. AMD uses Socket FP8, while Intel uses Socket 1700. The AMD part has multiple part numbers (100-000001323, 100-000001375, 100-000001312), while Intel lists a single part number (SRPLV). Neither processor has an unlocked multiplier, so overclocking is not supported on either platform.

Where Each One Wins

The AMD Ryzen 7 8840U wins in data-heavy and general-purpose workloads. Its 45.8% lead in data encryption makes it the clear choice for security-related tasks. The 46.1% advantage in random string sorting suggests strength in database or sorting operations. A 39.5% win in integer math points to general computational efficiency. The 33.8% lead in data compression favors archiving and file-handling workloads. For everyday multitasking, the 27.1% PassMark multithread win indicates better overall throughput on common parallel tasks.

The Intel Xeon 6333P wins in specific rendering and physics scenarios. The 16.9% Cinebench R23 multicore lead suggests it handles long-form rendering workloads better, despite having fewer cores. The 22.7% singlecore advantage in the same suite indicates superior per-thread rendering performance. The 10.9% win in PassMark physics points to strength in simulation or physics-based computations. The 6% edge in find prime numbers is marginal but consistent with a mathematical workload advantage.

The Intel part also offers features the AMD chip lacks: ECC memory support and DDR4 compatibility. These are relevant for server or workstation deployments where data integrity and memory flexibility are priorities. The AMD chip counters with integrated Radeon 780M graphics, making it a more complete package for systems without a discrete GPU. The mobile market segment and 28W TDP of the AMD chip make it suitable for power-constrained environments, while the 65W TDP of the Intel part requires more robust cooling. The launch MSRP of the Intel Xeon 6333P is $319.
