AMD EPYC 7502 vs Intel Core i5-9500 Comparison

The Verdict

The AMD EPYC 7502 is the decisive winner in every recorded benchmark comparison. Across all six head-to-head tests, the EPYC 7502 outperforms the Intel Core i5-9500 by approximately 82.5% in each instance. The data shows no benchmark category where the Intel part takes a lead. This is a lopsided comparison between a 32-core, 64-thread server processor and a 6-core, 6-thread desktop chip.

The Intel Core i5-9500 targets desktop users who need a straightforward 6-core processor with integrated graphics. It has a higher boost clock of 4.30 GHz and a lower TDP of 65 watts. The EPYC 7502, by contrast, is a server and workstation part with 32 cores, 64 threads, and a TDP of 180 watts. Its multithreaded performance is in a completely different class.

For buyers choosing between these two, the decision hinges on workload. If the task is single-threaded desktop responsiveness with modest power draw, the i5-9500 offers a 3.00 GHz base clock and a 4.30 GHz boost clock. If the task is heavily threaded server work, virtualization, or data center duty, the EPYC 7502 dominates with its 32-core architecture and massive 128 MB L3 cache.

The database percentile rankings show both processors sit near each other in overall standing. The i5-9500 ranks in the 68th percentile among all CPUs, while the EPYC 7502 ranks in the 67th percentile. This is a reminder that percentile rankings blend many workload types, and a server chip's true strength appears only in multithreaded tests.

The verdict is simple: the EPYC 7502 wins every benchmark comparison. The i5-9500 remains a viable desktop part for users who value its integrated graphics, lower power envelope, and higher boost clock, but in raw compute performance, the EPYC 7502 is the clear choice.

A: The i5-9500 has an average benchmark score of 13452, while the EPYC 7502 has an average score of 12709. Despite losing every head-to-head test, the i5-9500 has a higher average score because the EPYC 7502's benchmark suite includes fewer tests, and the averages are calculated differently across different test sets.

Architecture Differences

The Intel Core i5-9500 uses the Coffee Lake architecture, specifically the Coffee Lake Refresh generation. It is built on Intel's 14 nm process node and manufactured by Intel. The EPYC 7502 uses AMD's Zen 2 architecture with the codename Rome. It is built on a 7 nm process node and manufactured by TSMC. The process node difference is significant: 14 nm versus 7 nm, with the smaller node offering density and efficiency advantages for the EPYC.

The i5-9500 has 6 cores and 6 threads, meaning no hyper-threading support. The EPYC 7502 has 32 cores and 64 threads, meaning each core supports two threads. This is a fundamental architectural difference. The EPYC 7502 also carries 3,800 million transistors on a 74 mm² die, while the i5-9500's transistor count and die size are not recorded in the database.

Cache hierarchies differ substantially. The i5-9500 provides 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 9 MB of shared L3 cache. The EPYC 7502 provides 96 KB of L1 cache per core, 512 KB of L2 cache per core, and 128 MB of shared L3 cache. The EPYC's 128 MB L3 cache is more than fourteen times larger than the i5's 9 MB L3 cache, which is critical for server workloads with large working sets.

Memory architecture also differs. The i5-9500 supports DDR4 memory through a dual-channel bus with 42.7 GB/s bandwidth. The EPYC 7502 supports DDR4 through an eight-channel bus with 204.8 GB/s bandwidth. The EPYC also supports ECC memory, while the i5 does not. This makes the EPYC 7502 suitable for memory-intensive and error-tolerant enterprise workloads.

PCIe capabilities differ as well. The i5-9500 provides PCIe Gen 3 with 16 lanes from the CPU. The EPYC 7502 provides PCIe Gen 4, though the lane count is not specified in the database. PCIe Gen 4 doubles the bandwidth per lane compared to Gen 3, which matters for high-throughput storage and accelerator cards.

The i5-9500 includes integrated UHD 630 graphics, while the EPYC 7502 has no integrated graphics. This reflects their target markets: the i5 is a desktop part where integrated graphics reduce system cost, and the EPYC is a server part where a discrete GPU or management controller provides display output.

Specification Differences

The two processors differ across nearly every specification field. The i5-9500 has 6 cores and 6 threads, while the EPYC 7502 has 32 cores and 64 threads. Base clocks are 3.00 GHz for the i5 and 2.50 GHz for the EPYC. Boost clocks are 4.30 GHz for the i5 and 3.35 GHz for the EPYC. The i5 has higher clock speeds, but far fewer cores.

TDP differs dramatically. The i5-9500 is rated at 65 watts, while the EPYC 7502 is rated at 180 watts. This reflects the EPYC's larger core count and server-oriented power delivery. The i5 uses Intel Socket 1151, while the EPYC uses AMD Socket SP3. These sockets are not interchangeable.

Process node and foundry differ. The i5 is built on Intel's 14 nm process at Intel's foundry. The EPYC is built on TSMC's 7 nm process. The EPYC's transistor count is recorded at 3,800 million on a 74 mm² die, while those figures are not recorded for the i5.

Memory support differs in channel count and bandwidth. The i5 uses dual-channel memory with 42.7 GB/s bandwidth. The EPYC uses eight-channel memory with 204.8 GB/s bandwidth. ECC support is absent on the i5 and present on the EPYC.

Cache specifications differ at every level. The i5 has 64 KB L1 per core, 256 KB L2 per core, and 9 MB shared L3. The EPYC has 96 KB L1 per core, 512 KB L2 per core, and 128 MB shared L3.

PCIe generation differs. The i5 provides PCIe Gen 3 with 16 CPU lanes. The EPYC provides PCIe Gen 4, with lane count not recorded. Integrated graphics are present on the i5 as UHD 630, while the EPYC has none.

Market segment and production status differ. The i5 is a desktop part that is end-of-life. The EPYC is a server and workstation part that remains active in production. Release dates differ as well: the i5 launched in October 2018, while the EPYC launched in August 2019. The i5's part number is SR3XG, and the EPYC's part number is 100-000000054.

Head-to-Head Benchmarks

The head-to-head data shows a clean sweep for the AMD EPYC 7502 across all six recorded tests. In Cinebench R15 multicore, the EPYC 7502 scores 4428 against 776 for the i5-9500, a delta of 82.5% in favor of AMD. In Cinebench R15 single-core, the EPYC scores 625 against 109, again 82.5% ahead.

Cinebench R20 follows the same pattern. In multicore, the EPYC scores 18454 versus 3236 for the i5. In single-core, the EPYC scores 2605 versus 456. Both tests show the same 82.5% gap.

Cinebench R23 continues the trend. In multicore, the EPYC scores 43940 against 7705 for the i5. In single-core, the EPYC scores 6203 against 1087. The delta is again 82.5% in each case.

The consistency of the 82.5% delta across all six tests is notable. It suggests the performance gap is structural, driven by the core and thread count difference, rather than workload-specific. The EPYC 7502's 32 cores and 64 threads give it a massive advantage in any parallel workload. The i5-9500's higher boost clock of 4.30 GHz does not compensate for having only 6 cores.

The i5-9500 has additional benchmark results not present in the head-to-head comparison. These include Geekbench multicore at 5402, Geekbench single-core at 1448, and a range of PassMark tests. The EPYC 7502 has no recorded results for these tests in the head-to-head set, so direct comparisons are unavailable. However, the available data is unambiguous: in every test where both processors were measured, the EPYC 7502 wins.

The average benchmark scores tell a different story. The i5-9500 has an average score of 13452, while the EPYC 7502 has an average score of 12709. This is because the average includes different test sets. The i5's average includes Geekbench and PassMark results that are not recorded for the EPYC. The EPYC's average includes only Cinebench tests, which are heavily multithreaded and thus lower on an absolute scale for a server chip with lower single-thread clocks.

Where Each One Wins

The AMD EPYC 7502 wins every recorded benchmark comparison, so the use-case split is defined by workload type rather than benchmark victories. The EPYC 7502 is the clear choice for heavily threaded server workloads. Its 32 cores, 64 threads, 128 MB L3 cache, and 204.8 GB/s memory bandwidth make it suited for virtualization, database serving, and compute-intensive data center tasks. Its ECC memory support adds reliability for long-running server operations. Its active production status means it remains available for new server builds.

The Intel Core i5-9500 has no benchmark wins, but it holds advantages in specific areas. Its 65 watt TDP makes it far more power-efficient for desktop use. Its 4.30 GHz boost clock is higher than the EPYC's 3.35 GHz boost clock, which benefits lightly threaded desktop applications. Its UHD 630 integrated graphics allow a system to run without a discrete GPU. Its dual-channel memory architecture is sufficient for typical desktop workloads. Its end-of-life status limits its appeal for new builds, but it remains a viable option for budget desktop systems where integrated graphics and low power draw matter.

The percentile rankings show both processors near the middle of the database: the i5 at the 68th percentile and the EPYC at the 67th percentile. This indicates that while the EPYC dominates this specific head-to-head, the i5's broader benchmark suite, including single-threaded and desktop-oriented tests, keeps its overall standing competitive.

For users who need maximum multithreaded compute, the EPYC 7502 is the only choice. For users who need a simple desktop processor with integrated graphics, low power draw, and a high boost clock, the i5-9500 remains relevant. The data does not support any other conclusion.
