AMD EPYC 8024P vs AMD Ryzen 5 7545U Comparison

The AMD Ryzen 5 7545U and AMD EPYC 8024P represent two vastly different corners of the AMD lineup: a 28-watt mobile processor aimed at thin-and-light laptops, and a 90-watt server chip built for dense, single-socket workstations. Despite this, their benchmark scores are surprisingly close, with the Ryzen 5 7545U averaging 26,849 points and the EPYC 8024P averaging 26,555 points. The data shows a near-tie in aggregate performance, but each chip wins in distinctly different workloads, making the choice between them a question of workload fit rather than raw speed.

Where Each One Wins

The AMD EPYC 8024P is the clear winner in multi-threaded and server-oriented tasks. It takes 12 of the 17 head-to-head benchmark comparisons, including every Cinebench R15, R20, and R23 test, both single-core and multi-core. In Cinebench R23 multi-core, it scores 17,472 versus the Ryzen’s 17,253, a 1.3% edge. The EPYC also dominates in passmark physics (1,905 vs 1,057, a 44.5% lead), prime number finding (109 vs 68, a 37.6% lead), and data encryption (15,809 vs 14,202, a 10.2% lead). These are compute-heavy, parallel workloads that benefit from the EPYC’s 8 cores and 16 threads.

The AMD Ryzen 5 7545U wins the other five benchmarks, and its victories are concentrated in areas where its higher boost clock and newer architecture help. The biggest win is in passmark single-thread, where it scores 3,673 versus the EPYC’s 2,371, a massive 54.9% advantage. It also wins passmark extended instructions (17,865 vs 14,251, a 25.4% lead), floating-point math (36,754 vs 34,757, a 5.7% lead), and data compression (238,345 vs 232,242, a 2.6% lead). If your workload relies on integer-heavy single-thread performance or AVX-style instruction extensions, the Ryzen 5 7545U is the stronger pick.

Architecture Differences

The two chips are built on different Zen 4 variants. The Ryzen 5 7545U uses the standard Zen 4 architecture with the codename Phoenix2, fabricated on TSMC’s 4 nm process. It packs 20,900 million transistors into a 137 mm² die. The EPYC 8024P uses Zen 4c, the dense-core variant, codenamed Siena, on a 5 nm process with 8,875 million transistors in a 73 mm² die. The Zen 4c cores are designed for power efficiency and core density, which explains the EPYC’s lower clock speeds but higher core count.

The EPYC 8024P has 8 cores and 16 threads, while the Ryzen 5 7545U has 6 cores and 12 threads. However, the Ryzen boosts much higher: 4.90 GHz versus the EPYC’s 3.00 GHz, with base clocks of 3.20 GHz and 2.40 GHz respectively. Cache configurations also differ. Both have 64 KB of L1 and 1 MB of L2 per core, but the EPYC has 32 MB of shared L3 cache, double the Ryzen’s 16 MB. The EPYC also supports six-channel DDR5 memory with 230.4 GB/s bandwidth, versus the Ryzen’s dual-channel 89.6 GB/s. Both support ECC memory.

The platform features diverge sharply. The Ryzen 5 7545U uses AMD Socket FP7, has a Radeon 740M integrated GPU, and supports PCIe Gen 4 with 14 CPU lanes. The EPYC 8024P uses AMD Socket SP6, has no integrated graphics, and supports PCIe Gen 5 with 96 CPU lanes. The EPYC also has a launch MSRP of $409, while the Ryzen’s price is not listed.

FAQ

Q: Which CPU has integrated graphics?

A: Only the AMD Ryzen 5 7545U has integrated graphics, featuring the Radeon 740M. The AMD EPYC 8024P has no integrated graphics, so a discrete GPU is required for display output.

Specification Differences

The most obvious difference is core count. The EPYC 8024P has 8 cores and 16 threads, while the Ryzen 5 7545U has 6 cores and 12 threads. Clock speeds favor the Ryzen: its base clock is 3.20 GHz and boost clock is 4.90 GHz, versus the EPYC’s 2.40 GHz base and 3.00 GHz boost. Power consumption is also starkly different, with the Ryzen rated at 28 W TDP and the EPYC at 90 W TDP.

The process node differs, with the Ryzen on 4 nm and the EPYC on 5 nm. The Ryzen’s die is 137 mm² with 20,900 million transistors, while the EPYC’s die is 73 mm² with 8,875 million transistors. L3 cache is double on the EPYC: 32 MB shared versus 16 MB shared. Memory support is a major split: the Ryzen uses dual-channel DDR5 with 89.6 GB/s bandwidth, while the EPYC uses six-channel DDR5 with 230.4 GB/s bandwidth.

Platform connectivity is another differentiator. The Ryzen 5 7545U uses Socket FP7, has PCIe Gen 4 with 14 lanes, and includes a Radeon 740M iGPU. The EPYC 8024P uses Socket SP6, has PCIe Gen 5 with 96 lanes, and lacks integrated graphics. The EPYC also has a launch MSRP of $409, while the Ryzen’s launch MSRP is not listed. Both are active production parts, with the EPYC released on 2023-09-17 and the Ryzen on 2023-11-01.

Head-to-Head Benchmarks

Starting with Cinebench, the EPYC 8024P wins every single test, but by narrow margins. In R15 multi-core, it scores 1,761 versus 1,739, a 1.2% lead. In R20 multi-core, the gap is 7,338 versus 7,246, a 1.3% lead. The R23 multi-core results are similar: 17,472 versus 17,253, again a 1.3% lead. Single-core results are equally close — the EPYC wins R23 single-core with 2,466 versus 2,435, a 1.3% lead. These are essentially negligible differences, well within run-to-run variance.

The Passmark results tell a more polarized story. The Ryzen 5 7545U’s single-thread score of 3,673 crushes the EPYC’s 2,371, a 54.9% blowout. That is the largest delta in the entire comparison. The Ryzen also wins extended instructions by 25.4% (17,865 vs 14,251) and floating-point math by 5.7% (36,754 vs 34,757). It edges out the EPYC in data compression by 2.6% (238,345 vs 232,242).

The EPYC’s wins are more varied. Its biggest is in passmark physics, where it scores 1,905 versus 1,057, a 44.5% margin. It also wins prime number finding by 37.6% (109 vs 68), random string sorting by 12.3% (34,613 vs 30,358), and data encryption by 10.2% (15,809 vs 14,202). In integer math, the EPYC wins by 3.1% (62,128 vs 60,206), and in the passmark multithread test, it wins by 1.3% (20,556 vs 20,298). The EPYC wins 12 benchmarks, the Ryzen wins 5.

The Verdict

The data points to a simple conclusion: if you need a server or workstation CPU for multi-threaded, parallel, or memory-bandwidth-intensive workloads, the AMD EPYC 8024P is the correct choice. It wins the vast majority of benchmarks, offers double the L3 cache, six-channel memory, and 96 PCIe Gen 5 lanes. Its 44.5% lead in physics and 37.6% lead in prime number finding highlight its strength in scientific and simulation tasks. The EPYC’s 8-core, 16-thread configuration and 90 W TDP make it a proper server part, and it holds a 78th percentile ranking versus all CPUs.

If your priority is single-thread responsiveness or you need a chip for a mobile device, the AMD Ryzen 5 7545U is the only option here. Its 54.9% single-thread advantage is decisive, and it also wins in extended instructions and floating-point math. The 28 W TDP, integrated Radeon 740M, and Socket FP7 make it suitable for laptops, not servers. Its 79th percentile ranking is marginally higher than the EPYC’s 78th, reflecting its strong all-around performance despite fewer cores.

There is no overall winner — the aggregate scores are too close, with the Ryzen averaging 26,849 and the EPYC 26,555. Instead, the choice is dictated by platform and workload. The EPYC 8024P is for rack-mounted density and heavy parallel compute; the Ryzen 5 7545U is for portable, single-threaded efficiency. Pick the EPYC for servers, the Ryzen for mobile.
