AMD Ryzen Threadripper PRO 9955WX vs Intel Core 7 251E Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark comparisons between the AMD Ryzen Threadripper PRO 9955WX and the Intel Core 7 251E. The database contains a full benchmark suite for the AMD processor, while the Intel Core 7 251E has no recorded benchmark scores. This absence of direct measurement data means a definitive performance comparison cannot be established from the available facts.

The AMD Ryzen Threadripper PRO 9955WX delivers substantial multi-core performance in the recorded tests. In Cinebench R23, it scores 59,494 in multi-core and 8,399 in single-core. Its Cinebench R20 results show 24,987 multi-core and 3,527 single-core. The Cinebench R15 scores are 5,996 multi-core and 846 single-core. PassMark results include 67,035 in multithread, 4,530 in single-thread, 236,120 in integer math, 156,215 in floating point math, 920,954 in data compression, 44,389 in data encryption, 76,363 in extended instructions, and 337 in find prime numbers.

The AMD processor's average benchmark score of 101,041 places it in the 97th percentile among all CPUs in the database. Its nearest rivals include the AMD EPYC 7513 with an average score of 102,244 and a delta of -1.2%, the AMD EPYC 4585PX with 99,324 and a delta of 1.7%, the AMD EPYC 8324P with 103,329 and a delta of -2.2%, and the AMD Ryzen Threadripper PRO 5965WX with 98,504 and a delta of 2.6%. These deltas indicate the 9955WX sits within a tight cluster of server and workstation processors, trailing the EPYC 8324P by 2.2% and the EPYC 7513 by 1.2%, while leading the EPYC 4585PX by 1.7% and the Threadripper PRO 5965WX by 2.6%. The data suggests the 9955WX performs near the top of its comparison group, with all four nearest rivals within roughly 2.6% of its average score.

The Intel Core 7 251E has no benchmark entries, no average score, and no nearest rivals in the database. Its percentile rank of 50 reflects a mid-pack position, but this is based on the absence of recorded measurements rather than actual performance data. The database records no wins for either processor in head-to-head testing, as no head-to-head benchmarks exist.

Architecture Differences

The two processors diverge significantly in their underlying designs. The AMD Ryzen Threadripper PRO 9955WX uses the Zen 5 architecture under the codename Shimada Peak, fabricated on a 4 nm process at TSMC. It contains 16,630 million transistors across a die size of 2x 70.6 mm². The Intel Core 7 251E uses the Bartlett Lake codename, fabricated on a 10 nm process at Intel, with a die size of 257 mm². The database does not list a transistor count for the Intel processor.

Core configurations differ substantially. The AMD processor has 16 cores and 32 threads, while the Intel processor has 24 cores and 32 threads. Despite fewer cores, the AMD chip runs at a base clock of 4.50 GHz and boosts to 5.40 GHz. The Intel chip operates at a base clock of 2.10 GHz and boosts to 5.60 GHz. The higher base clock of the AMD processor suggests it maintains full performance across all cores under sustained loads, while the Intel processor relies on boost behavior to reach higher frequencies.

Cache hierarchies also differ. The AMD processor provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of L3 cache. The Intel processor offers 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The AMD chip's larger L3 capacity, 64 MB versus 36 MB, provides more room for frequently accessed data across its 16 cores.

Memory architecture presents a major distinction. The AMD processor supports DDR5 memory with an eight-channel memory bus and 409.6 GB/s of memory bandwidth. The Intel processor supports both DDR4 and DDR5 with a dual-channel memory bus and 89.6 GB/s of memory bandwidth. This represents a roughly 4.6x difference in theoretical memory bandwidth, which matters for memory-intensive workloads.

PCIe connectivity differs as well. The AMD processor provides Gen 5 with 128 lanes from the CPU, while the Intel processor provides Gen 5 with 16 lanes from the CPU. This eightfold difference in PCIe lane count affects expansion capability for GPUs, storage controllers, and networking. The AMD processor uses AMD Socket sTR5, while the Intel processor uses Intel Socket 1700.

The AMD processor includes no integrated graphics, while the Intel processor includes UHD Graphics 770. The AMD processor has an unlocked multiplier, while the Intel processor does not. Both processors support ECC memory. The AMD processor's TDP is 350, while the Intel processor's TDP is 65, indicating a substantial difference in power envelope.

The Verdict

The data presents a clear division. The AMD Ryzen Threadripper PRO 9955WX sits in the 97th percentile among all CPUs with an average benchmark score of 101,041. The Intel Core 7 251E sits in the 50th percentile with no recorded benchmark scores. For workloads that demand maximum multi-threaded throughput, high memory bandwidth, and extensive PCIe expansion, the AMD processor's recorded performance and architectural provisions make it the stronger choice based on available data.

The Intel Core 7 251E, with its 24 cores and 32 threads, offers a different balance. Its lower TDP of 65 suggests it fits in power-constrained environments, and its dual-channel memory and 16 PCIe lanes indicate a more mainstream desktop orientation. The integrated UHD Graphics 770 provides display output without a discrete GPU, which the AMD processor cannot do.

The data does not support a performance comparison because the Intel processor lacks benchmark measurements. The AMD processor's percentile rank of 97 versus the Intel processor's 50 reflects the availability of data as much as actual capability. The choice between these processors depends entirely on the workload characteristics and system requirements, with the AMD processor demonstrating strong multi-core and memory performance in recorded tests while the Intel processor's performance remains unquantified in the database.

Where Each One Wins

The AMD Ryzen Threadripper PRO 9955WX wins in scenarios requiring maximum multi-core throughput. Its Cinebench R23 multi-core score of 59,494 and PassMark multithread score of 67,035 demonstrate strong parallel processing capability. The eight-channel memory bus with 409.6 GB/s bandwidth supports data-heavy workloads such as large dataset manipulation and scientific computing. The 128 PCIe Gen 5 lanes enable extensive expansion for multiple GPUs, storage arrays, and high-speed networking. The 64 MB L3 cache provides substantial on-die storage for frequently accessed data. The unlocked multiplier allows frequency adjustment for users who need it. The 97th percentile ranking places it among the top processors in the database.

The Intel Core 7 251E wins in scenarios where power efficiency and integrated graphics matter. Its TDP of 65 represents a much lower power envelope than the AMD processor's 350, making it suitable for compact or thermally constrained systems. The integrated UHD Graphics 770 eliminates the need for a discrete GPU in basic display applications. The dual-channel memory support for both DDR4 and DDR5 offers flexibility in memory selection. The 24 cores provide parallel processing capability, though the lower base clock of 2.10 GHz and the 36 MB shared L3 cache suggest a different performance profile. The 16 PCIe Gen 5 lanes cover standard desktop expansion needs. The 50th percentile ranking reflects its mid-pack position in the database, though this is based on the absence of benchmark data rather than measured performance.

The data shows the AMD processor as a high-performance workstation and server part with exceptional memory bandwidth, PCIe expansion, and recorded multi-core results. The Intel processor appears as a mainstream desktop part with lower power consumption and integrated graphics. Without benchmark measurements for the Intel processor, the database cannot quantify its performance relative to the AMD processor. The AMD processor's recorded scores and architectural specifications position it for heavy compute workloads, while the Intel processor's specifications position it for general-purpose desktop use where power draw and integrated graphics are priorities.
