Architecture Differences

The two CPUs come from fundamentally different design philosophies. The Intel Core Ultra 7 270K Plus is built on a 3 nm process node and uses the Arrow Lake Refresh codename, part of the Core Ultra Series 2. The AMD EPYC 4584PX uses the Zen 4 architecture with the Raphael codename, built on a 5 nm process node. Both are manufactured by TSMC, but the transistor counts are nearly identical: 17,800 million for Intel and 17,840 million for AMD. The die sizes differ significantly, with Intel using a single 243 mm² die and AMD using two 71 mm² dies.

Cache hierarchy is a major architectural split. The Intel part provides 192 KB of L1 cache per core and 3 MB of L2 cache per core, with 36 MB of shared L3. The AMD part offers 64 KB of L1 per core and 1 MB of L2 per core, but its shared L3 cache is 128 MB, and it includes a dedicated 64 MB 3D V-Cache slice. This large L3 pool is designed for server workloads that repeatedly access large datasets.

The Intel part is a desktop segment CPU with an unlocked multiplier, allowing overclocking. The AMD part is a server/workstation CPU with a locked multiplier. The Intel uses Socket 1851, while the AMD uses Socket AM5. The Intel has 20 PCIe Gen 5 lanes from the CPU, whereas the AMD has 28 PCIe Gen 5 lanes from the CPU. The Intel integrates Arc Xe-LPG Graphics with 64 execution units; the AMD integrates Radeon Graphics. Both support DDR5 memory and dual-channel memory buses, but the Intel has a higher memory bandwidth rating at 115.2 GB/s versus 83.2 GB/s for the AMD.

Head-to-Head Benchmarks

The largest Intel win comes in PassMark floating-point math, where the Core Ultra 7 270K Plus scores 229491 versus 121460, a 88.9% advantage. This is a massive gap and suggests the Intel architecture is far stronger at FPU-heavy calculations. The Intel also wins PassMark find prime numbers by 39.5% (615 vs 441), PassMark single-thread by 33.5% (5068 vs 3795), and PassMark data encryption by 28.7% (59097 vs 45902). In Cinebench R15 multi-core, the Intel wins by 28.2% (6656 vs 5193). The Intel also takes Cinebench R20 multi-core by 13% (24461 vs 21640) and single-core by 13% (3453 vs 3055), plus PassMark extended instructions by 18.1% (63506 vs 53774), PassMark multithread by 18% (68574 vs 58117), data compression by 8.5% (804322 vs 741648), and random string sorting by 10.6% (96945 vs 87690).

The AMD EPYC 4584PX wins are concentrated in a few specific tests. The most striking is Cinebench R23 single-core, where the AMD scores 7274 versus 2439, a 66.5% advantage. That is the largest single delta in either direction. The AMD also wins Cinebench R23 multi-core by 14.1% (51524 vs 44253). In PassMark integer math, the AMD wins by 12.8% (201919 vs 175986). The AMD wins PassMark physics by 11.1% (4574 vs 4064). The AMD also wins Cinebench R15 single-core by 51.7% (733 vs 354), though that test appears to produce unusually low numbers for the Intel part.

Where Each One Wins

The Intel Core Ultra 7 270K Plus is the clear winner for general desktop and workstation workloads that involve floating-point math, encryption, compression, and single-threaded responsiveness. Its 88.9% lead in floating-point math makes it a strong candidate for scientific computing or financial modeling. The 33.5% single-thread advantage means everyday app responsiveness and older software that relies on one core will feel faster. The Intel also leads in PassMark multithread by 18%, so its 24 physical cores provide a solid overall throughput advantage in most parallel tasks. The unlocked multiplier is another point in its favor for enthusiasts who want to extract more performance.

The AMD EPYC 4584PX wins in Cinebench R23, which is a widely used render benchmark. Its 14.1% lead in R23 multi-core and 66.5% lead in R23 single-core indicate that this specific workload responds very well to the AMD's Zen 4 architecture and large L3 cache. The 128 MB shared L3 with 3D V-Cache is likely the reason for the R23 dominance. The AMD also wins integer math and physics, which point toward database queries, integer-heavy server logic, and physics simulation. The server/workstation segment and 28 PCIe Gen 5 lanes make the AMD a better fit for systems with many expansion cards or NVMe drives.

The database shows 12 wins for Intel and 5 for AMD. However, the AMD wins include the two most recent Cinebench versions (R23 multi and single), which may carry more weight for renderers. The Intel wins are broader across PassMark's suite, covering 10 of the 12 PassMark tests. The choice comes down to workload: if your primary tool is Cinebench-based rendering, the EPYC 4584PX is the better pick. If you need a jack-of-all-trades CPU for mixed desktop and compute tasks, the Core Ultra 7 270K Plus has the wider lead. The AMD costs more at launch MSRP, but this analysis does not consider price-to-performance.
