Architecture Differences

The two processors come from different design philosophies. The i5-8265U is built on Intel's Whiskey Lake architecture using a 14 nm process at Intel's own foundry. It packs 4 cores and 8 threads, with a base clock of 1600 MHz and a boost clock of 3.90 GHz. Its cache layout includes 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3. The memory controller is dual-channel DDR4, delivering 38.4 GB/s, and it does not support ECC. PCIe connectivity is Gen 3 with 16 lanes from the CPU. The integrated UHD Graphics 620 makes it a self-contained mobile solution, and the BGA 1528 socket is soldered onto the motherboard.

The EPYC 7302 is a Zen 2 part, codenamed Rome, fabricated on a 7 nm process at TSMC. It has 16 cores and 32 threads, with a base clock of 3.00 GHz and a boost clock of 3.30 GHz. The L1 cache is the same 64 KB per core, but L2 doubles to 512 KB per core, and L3 is organized as 32 MB per die, totaling 128 MB across the chip. The memory subsystem is eight-channel DDR4, providing 204.8 GB/s, and ECC is supported. PCIe is Gen 4 with 128 lanes, a massive expansion capability. The EPYC 7302 has no integrated graphics, uses the AMD Socket SP3, and is designed for server and workstation platforms. It contains 15,200 million transistors across four 74 mm² dies, and its production status is active, while the i5-8265U is end-of-life.

The architectural gap is stark: the EPYC 7302 has four times the cores, eight times the threads, over twenty times the L3 cache, and more than five times the memory bandwidth. The i5-8265U counters with a much higher boost clock and a low 15 W TDP, but its 14 nm process and smaller core count limit its raw throughput.

Where Each One Wins

In the recorded head-to-head Cinebench results, the EPYC 7302 wins all six tests. The i5-8265U has Passmark scores in the database, but the EPYC 7302 has no Passmark entries, so the direct comparison is limited to Cinebench. Within that scope, the EPYC 7302 dominates every multi-core and single-core workload.

The i5-8265U's strengths lie outside raw compute. Its 15 W TDP makes it suitable for thin-and-light laptops, and the integrated UHD Graphics 620 eliminates the need for a discrete GPU in basic systems. The BGA socket and mobile market segment confirm its intended use in portable devices. The EPYC 7302, with a 155 W TDP, eight-channel memory, ECC support, and 128 PCIe Gen 4 lanes, is built for server racks, virtualization, and memory-intensive workloads. The data shows that the EPYC 7302 is the clear performance leader, but the i5-8265U wins on power efficiency and integrated graphics.

The table highlights the fundamental differences. The EPYC 7302 offers more cores, more cache, more memory channels, and more PCIe lanes. The i5-8265U has a higher boost clock and integrated graphics, but its lower TDP and mobile socket define its role.

Head-to-Head Benchmarks

The database records six Cinebench tests, and the EPYC 7302 wins all of them. In Cinebench R15 multi-core, the i5-8265U scores 451 against the EPYC 7302's 2836, a delta of -84.1%. In R15 single-core, the i5-8265U scores 63 versus 400, a delta of -84.2%. The pattern continues in R20: multi-core 1882 vs 11818 (-84.1%), single-core 265 vs 1668 (-84.1%). In R23, the i5-8265U scores 4482 multi-core and 632 single-core, while the EPYC 7302 scores 28140 and 3972 respectively, both with a delta of -84.1%.

These deltas mean the i5-8265U's scores are roughly 84% lower than the EPYC 7302's in every test. The EPYC 7302's multi-core advantage is particularly pronounced: in R23 multi-core, it scores more than six times higher. Even in single-core tests, where the i5-8265U's higher boost clock might suggest an edge, the EPYC 7302 still leads by a wide margin. The EPYC 7302's Zen 2 architecture and larger cache clearly overcome the clock speed deficit.

The Verdict

The benchmark data is unambiguous: the AMD EPYC 7302 outperforms the Intel Core i5-8265U in every recorded Cinebench test, often by a factor of six or more. However, the two processors serve different markets. The i5-8265U is a mobile part with a 15 W TDP, integrated UHD Graphics 620, and a BGA socket, making it ideal for laptops and compact systems where power draw and space are critical. The EPYC 7302 is a server/workstation chip with 16 cores, 32 threads, ECC memory support, eight-channel memory, and 128 PCIe Gen 4 lanes, designed for heavy multi-threaded workloads, virtualization, and data-center applications.

If you need a low-power CPU with built-in graphics for a portable device, the i5-8265U is the appropriate choice. If you need raw multi-threaded performance, high memory bandwidth, and server-grade features, the EPYC 7302 is the clear winner. The recorded data shows no scenario where the i5-8265U beats the EPYC 7302 in Cinebench, so the decision rests entirely on the target platform and workload.
