AMD Ryzen 7 PRO 9745 vs Intel Xeon Platinum 8270 Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear split: the AMD Ryzen 7 PRO 9745 wins 6 of the 11 head-to-head tests, while the Intel Xeon Platinum 8270 takes 5. However, the margins tell a more interesting story than the raw win count.

The AMD’s most dominant victory comes in data encryption, where it scores 22,848 versus Intel’s 8,798, a massive 159.7% advantage. This is not a small edge; it is a complete reversal of the core-count narrative. The AMD also crushes the Intel in single-thread performance, scoring 4,624 to 2,325, a 98.9% lead. This is nearly double the per-core throughput, aligning with the AMD’s much higher boost clock of 5.40 GHz versus the Intel’s 4.00 GHz.

Two other AMD wins are in the physics test and the prime numbers test. The AMD scores 2,026 in physics, which is 124.4% higher than the Intel’s 903. The find prime test shows an even larger gap: the AMD’s 188 score is 123.8% above the Intel’s 84. These indicate that the AMD’s single-thread strength and higher clock speed translate directly into latency-sensitive workloads that do not scale well across many cores.

The AMD also wins the multi-thread test, scoring 38,201 against the Intel’s 29,986, a 27.4% margin. This is surprising given the Intel has 26 cores and 52 threads versus the AMD’s 8 cores and 16 threads. The AMD’s per-core instruction throughput and the 4 nm process clearly compensate for the core deficit in this particular workload.

The Intel’s wins are in throughput-heavy tasks that scale with the core count. The largest Intel victory is in random string sorting, where it scores 80,208 versus the AMD’s 49,219, a 38.6% higher result. The Intel also leads in data compression: 728,144 versus 457,211, a 37.2% gap. Extended instructions go to the Intel (51,191 versus 36,800, a 28.1% edge), as do integer math (160,322 versus 124,167, a 22.6% lead) and floating point math (99,432 versus 82,461, a 17.1% lead).

The average benchmark score tells a similar story. The AMD has an average of 74,761, while the Intel sits at 71,370. The AMD’s percentile ranking is 95 versus the Intel’s 94. So the overall database average favors the AMD, but not by an enormous margin.

Where Each One Wins

The AMD Ryzen 7 PRO 9745 is the clear choice for workloads that depend on per-core speed, cryptographic operations, and physics or prime-number calculations. The data shows it is 90% faster in single-thread tasks, 159% faster in encryption, and 124% faster in physics and prime number searches. The AMD’s base clock of 3.80 GHz and boost of 5.40 GHz, combined with its Zen 4 architecture, make it superior for databases, game servers, or any real-time transaction processing where a single thread is the bottleneck. It also wins the general multi-thread test, meaning that even in parallel workloads, its 8 cores are so efficient that they outrun the Intel’s 26 older cores.

The Intel Xeon Platinum 8270 is the workhorse for bulk data manipulation. The compression, sorting, and integer math tests all require moving and reordering large volumes of data, and the Intel’s 52 threads shine there. The 38.6% lead in random string sorting and the 37.2% lead in data compression indicate that the Intel is better suited for archival, backup, or big-data preprocessing tasks. Extended instructions and floating-point math also favor the Intel, suggesting scientific simulation and media rendering workloads that can scale across its many cores.

The Intel’s 94th percentile versus the AMD’s 95th percentile is close, but the margin in the head-to-head data is more telling than the percentile ranks. The Intel’s average score of 71,370 vs the AMD’s 74,761 shows the AMD is more consistent across the benchmark suite, whereas the Intel’s wins are concentrated in a few specific throughput tests.

Architecture Differences

The AMD is built on a 4 nm process at TSMC, while the Intel uses a 14 nm process at Intel. This is a full node and a half difference, and it explains the AMD’s clock speed advantage: the AMD’s boost of 5.40 GHz versus the Intel’s 4.00 GHz. The AMD has 8,315 million transistors on a 70.6 mm² die, while the Intel has 8,000 million transistors on an unspecified die size. The transistor count is similar, but the AMD fits them into a much smaller area, which is why it can run at higher clocks. The AMD uses the Granite Ridge codename, part of the Zen 4 generation, while the Intel is Cascade Lake-SP. The AMD is on the newer architecture, and the data shows this in the single-thread performance.

The cache structures differ significantly. The AMD has 80 KB of L1 per core and 1 MB of L2 per core, with 32 MB of shared L3. The Intel has 64 KB of L1 per core and 1 MB of L2 per core, with 35.75 MB of shared L3. The AMD’s total cache per core is larger in terms of the L1, but the Intel’s total L3 is about 3.75 MB larger. However, the AMD’s 32 MB L3 is shared across just 8 cores, giving each core a larger slice of the cache (4 MB per core) versus the Intel’s 35.75 MB shared across 26 cores (about 1.375 MB per core). This cache-per-core advantage for the AMD can reduce memory latency for single-threaded tasks.

The AMD supports DDR5 memory with a dual-channel bus, achieving 89.6 GB/s of bandwidth. The Intel supports DDR4 memory, with no bus width or bandwidth listed. The AMD’s memory bandwidth is a major architectural advantage. The AMD also has integrated Radeon Graphics, while the Intel has none. Both support ECC memory, which is important for server use. The AMD uses the AMD Socket AM5, while the Intel uses Intel Socket 3647. The AMD supports PCIe Gen 5 with 24 lanes from the CPU, while the Intel’s PCIe information is not recorded.

The Verdict

The data points to a clear verdict for the AMD. It wins 6 of 11 head-to-head tests, including the crucial multi-threaded test, single-thread test, and encryption. The AMD’s average score is 3,391 points higher, and its percentile ranking is one point higher. The Intel only wins in specific throughput-heavy tasks like compression and sorting. For any general-purpose server or workstation, the AMD is the better choice. It is faster in the common workloads, has a much lower TDP (65W versus 205W), and uses newer memory and PCIe standards.

The Intel is only recommended for tasks that specifically involve massive data movement, such as data compression, string sorting, or integer math. In these, the Intel’s 26 cores and 52 threads provide a clear advantage. But for everything else, the AMD’s 8-core design wins. The Intel’s 94th percentile and average score of 71,370 are respectable, but the AMD’s 95th percentile and 74,761 average are better. The AMD is the correct pick for most workloads, and the Intel is a niche choice for specific data-processing tasks.
