AMD Ryzen 7 5800XT vs Intel Xeon Phi 7210 Comparison

The Verdict

The AMD Ryzen 7 5800XT is the clear benchmark winner in every recorded test, taking all 17 head-to-head comparisons against the Intel Xeon Phi 7210. The data shows a complete sweep, with no test where the Xeon Phi 7210 manages to outperform the Ryzen part. The Ryzen 7 5800XT is the correct choice for desktop users, gamers, and anyone running single-threaded or lightly threaded workloads.

The Intel Xeon Phi 7210, despite its massive 64 cores and 256 threads, posts scores that trail the Ryzen 7 5800XT in every category. The Xeon Phi 7210 belongs to a server and workstation segment, and its benchmark profile reflects an architecture designed for specialized parallel workloads, not general-purpose computing. However, based on the measured data, even in multithreaded tests where one might expect the Phi to excel, the Ryzen 7 5800XT wins decisively.

If you are building a desktop system, the choice is unambiguous: the Ryzen 7 5800XT. If you are evaluating a server or workstation part for a specific parallel-computing task, the Xeon Phi 7210 has a place, but the recorded benchmarks here do not show it winning a single test.

Architecture Differences

The AMD Ryzen 7 5800XT is built on the Zen 3 architecture with the codename Vermeer. It uses a 7 nm process at TSMC and contains 4,150 million transistors on a 74 mm² die. The processor has 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. It fits into the AMD Socket AM4 and carries a TDP of 105 watts. The cache layout includes 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3 cache. Memory support is DDR4 with a dual-channel bus and a memory bandwidth of 51.2 GB/s. ECC memory is supported. PCIe connectivity is Gen 4 with 20 lanes from the CPU. There is no integrated graphics. The multiplier is unlocked, and the processor is actively in production. The release date is July 30, 2024.

The Intel Xeon Phi 7210 uses the Knights Landing architecture, also known by the codename Knights Landing. It is built on a 14 nm process at Intel and contains 8,000 million transistors. The die size is not recorded. This processor has 64 cores and 256 threads, with a base clock of 1300 MHz and a boost clock of 1500 MHz. It fits into the Intel Socket 3647 and carries a TDP of 215 watts. The cache layout includes 32 KB of L1 per core and 512 KB of L2 per core, with no L3 cache recorded. Memory support is DDR4, but the memory bus width and memory bandwidth are not recorded. ECC memory is supported. PCIe details are not recorded, and integrated graphics are not listed. The multiplier is locked. The market segment is server and workstation. The release date is June 19, 2016.

The architectural gap is stark. The Ryzen 7 5800XT uses a modern 7 nm process, runs at much higher clock speeds, and has a large shared L3 cache. The Xeon Phi 7210 uses an older 14 nm process, runs at much lower clocks, and has no L3 cache at all. The Xeon Phi compensates with an extreme core count, but the benchmark data shows that this does not translate into superior performance in any measured test.

Head-to-Head Benchmarks

The head-to-head data is a one-sided affair. The AMD Ryzen 7 5800XT wins all 17 recorded tests. The largest win comes in the PassMark find prime numbers test, where the Ryzen scores 119 against 10, a lead of 1090 percent. The data encryption test is also a massive gap: 21461 against 3455, a lead of 521.2 percent. The single-thread tests show the biggest raw gaps. In PassMark single-thread, the Ryzen scores 3535 against 460, a lead of 668.5 percent. The same pattern appears in the Cinebench series. In Cinebench R23 multicore, the Ryzen scores 23794 against 6210, a lead of 283.2 percent. In Cinebench R23 single-core, the Ryzen scores 3359 against 876, a lead of 283.4 percent.

The Cinebench R15 and R20 tests follow the same pattern. In R15 multicore, the Ryzen scores 2398 against 625, a lead of 283.7 percent. In R15 single-core, the Ryzen scores 338 against 88, a lead of 284.1 percent. In R20 multicore, the Ryzen scores 9993 against 2608, a lead of 283.2 percent. In R20 single-core, the Ryzen scores 1410 against 367, a lead of 284.2 percent.

The PassMark multithread test shows the Ryzen at 28053 against 7306, a lead of 284 percent. The physics test shows 1355 against 198, a lead of 584.3 percent. The random string sorting test shows 35911 against 8956, a lead of 301 percent. The floating point math test shows 53808 against 29356, a lead of 83.3 percent. The integer math test shows 93942 against 84874, a lead of 10.7 percent. The extended instructions test shows 24270 against 18359, a lead of 32.2 percent. The data compression test shows 352002 against 332960, a lead of 5.7 percent.

The narrowest margin is in data compression, where the Ryzen leads by only 5.7 percent. The next narrowest is integer math at 10.7 percent. These are the only two tests where the Xeon Phi 7210 gets close, but it still loses.

Where Each One Wins

The AMD Ryzen 7 5800XT wins everywhere in the recorded data. There is no benchmark category where the Intel Xeon Phi 7210 takes a win. The Ryzen's dominance spans single-threaded, multithreaded, encryption, compression, physics, math, and sorting workloads.

The largest margins come in single-threaded performance and in tasks that rely on high clock speeds and low latency per core. The PassMark single-thread score of 3535 versus 460 shows a processor built for responsive desktop work. The Cinebench single-core results reinforce this. The Ryzen also excels in encryption, with a 521.2 percent lead, and in prime number finding, with a 1090 percent lead. These tasks reward the Ryzen's high clock speeds and modern architecture.

The Xeon Phi 7210, despite its 64 cores and 256 threads, does not win any test. Its closest results come in data compression and integer math, where the Ryzen leads by 5.7 and 10.7 percent respectively. This suggests that the Xeon Phi's massive thread count helps in some parallel workloads, but not enough to overcome the Ryzen's architectural advantages.

For a desktop user, the choice is clear: the Ryzen 7 5800XT delivers higher performance in every measured category. For a server or workstation operator considering the Xeon Phi 7210, the benchmark data shows that the Ryzen part is faster in all recorded tests, though the Xeon Phi may still be relevant for specialized workloads not covered by these benchmarks. The overall percentile ranking for both processors is 81, indicating they sit at the same level relative to all CPUs in the database, but the head-to-head scores show a decisive advantage for the AMD part.
