AMD EPYC 7262 vs Intel Core i5-13400T Comparison

The Intel Core i5-13400T and AMD EPYC 7262 represent two fundamentally different approaches to computing, yet their benchmark results place them in a surprisingly close contest. The EPYC 7262, a server-class processor built for massive throughput, wins all six head-to-head Cinebench tests, but the margins are consistently narrow, hovering around 3.6%. The i5-13400T, a low-power desktop chip, counters with a higher boost clock and a modern architecture, keeping the overall average benchmark score within a few points of its rival. This creates a fascinating split between raw server capability and efficient desktop engineering.

Where Each One Wins

The AMD EPYC 7262 is the clear winner in every measured multi-threaded and single-threaded Cinebench workload. Its dominance is uniform across all three Cinebench versions (R15, R20, and R23), with a consistent 3.6% lead in both single-core and multi-core tests. This suggests that AMD’s Zen 2 architecture, despite being an older design from 2019, delivers superior instruction-per-clock efficiency in rendering tasks. The EPYC’s eight-channel memory bus and 204.8 GB/s of memory bandwidth likely contribute to this sustained performance, allowing it to feed its cores without bottlenecks. For any workload that scales across threads—like video rendering, scientific simulation, or database processing—the data indicates the EPYC 7262 is the stronger choice.

The Intel Core i5-13400T, while losing every head-to-head benchmark, wins on attributes not captured by Cinebench scores. It has a drastically lower TDP of 35 watts versus the EPYC’s 155 watts, making it the only rational option for power-constrained environments. Its boost clock of 4.40 GHz far exceeds the EPYC’s 3.40 GHz, which hints at better responsiveness in lightly-threaded, bursty tasks even if Cinebench’s specific single-core test doesn’t reflect it. The i5-13400T also includes integrated UHD Graphics 730, a feature the EPYC lacks entirely, so any system requiring basic display output without a discrete GPU can only use the Intel part. Finally, the i5-13400T supports both DDR4 and DDR5 memory, offering platform flexibility that the EPYC’s DDR4-only controller cannot match.

Architecture Differences

The architectural chasm between these two processors is vast. The i5-13400T uses Intel’s Raptor Lake architecture, built on a 10 nm process at Intel’s own foundry. It packs 10 cores and 16 threads, with a die size of 215 mm². Its cache hierarchy is per-core: 80 KB of L1 and 1.25 MB of L2 per core, with a shared 20 MB L3 pool. It runs on Intel Socket 1700 and supports dual-channel memory in either DDR4 or DDR5 flavors, without ECC. PCIe connectivity is Gen 5 with 20 lanes from the CPU, and the chip integrates UHD Graphics 730. The TDP is a modest 35 watts, and it launched in January 2023 with a launch MSRP of $221.

The EPYC 7262, by contrast, is a Zen 2-based Rome part built on a 7 nm process at TSMC. It uses a chiplet design with four dies, each 74 mm², totaling 15,200 million transistors. It has 8 cores and 16 threads, with 64 KB of L1 and 512 KB of L2 per core, plus 32 MB of L3 per die, summing to a massive 128 MB total L3 cache. This is six and a half times the L3 capacity of the Intel chip. The EPYC runs on AMD Socket SP3, supports eight-channel DDR4 memory with 204.8 GB/s of bandwidth, and enables ECC memory. It provides Gen 4 PCIe with 128 lanes from the CPU, a server-grade feature that dwarfs the Intel part’s 20 Gen 5 lanes. Its TDP is 155 watts, and it launched in August 2019 with a launch MSRP of $575. The EPYC has no integrated graphics, targeting server workloads where discrete or remote management is standard.

Head-to-Head Benchmarks

The head-to-head data shows a consistent pattern of EPYC superiority across all six Cinebench tests. In Cinebench R15 multi-core, the EPYC scores 1780 against the i5-13400T’s 1716, a 3.6% advantage. The single-core R15 test tells the same story: EPYC 251 versus Intel 242, again 3.6% ahead. Moving to Cinebench R20, the EPYC posts 7418 in multi-core versus 7152, and 1047 in single-core versus 1009. The margins remain locked at 3.6%.

The Cinebench R23 results show the largest absolute gaps but the same relative difference. The EPYC scores 17662 in multi-core, while the i5-13400T manages 17029—a 633-point gap. In single-core R23, the EPYC hits 2493 against 2404, an 89-point edge. The uniformity of the 3.6% delta across all tests is remarkable; it suggests the performance difference is architectural rather than workload-dependent. The EPYC’s higher base clock of 3.20 GHz, compared to the i5-13400T’s 1.30 GHz base clock, likely explains why the AMD part wins even in single-threaded tests where the Intel chip’s 4.40 GHz boost should theoretically help. The EPYC’s boost clock is only 3.40 GHz, but its sustained base clock is much higher, meaning it can maintain performance without relying on boost headroom.

Outside these head-to-head tests, the i5-13400T shows strengths in other benchmark suites. It scores 10227 in Geekbench multi-core and 1899 in single-core, tests the EPYC was not measured on. The i5-13400T’s average benchmark score across all tests is 5210, placing it in the 60th percentile of all CPUs. The EPYC’s average score is slightly lower at 5109, also in the 60th percentile. Despite losing every Cinebench test, the i5-13400T actually has a higher average benchmark score due to its Geekbench results. The i5-13400T’s nearest rivals include the Intel Xeon E-2378G (0.2% behind), the Intel Core i9-10850K (0.6% ahead), and the Intel Core i7-11700B (0.6% ahead). The EPYC’s nearest rivals are the Intel Core i9-7900X (0.2% ahead), the Intel Core i7-11850HE (0.3% behind), and the Intel Xeon W-2155 (0.7% behind).

The Verdict

The data presents a clear but nuanced verdict. For pure compute performance in Cinebench-class workloads, the AMD EPYC 7262 is the winner. It beats the i5-13400T by 3.6% in every single and multi-core test, and its 128 MB of L3 cache, eight-channel memory, and 128 PCIe Gen 4 lanes make it the superior choice for server racks, virtualized environments, and memory-bandwidth-hungry applications. Its ECC memory support and massive memory bandwidth of 204.8 GB/s further cement its position for mission-critical workloads where data integrity and throughput are paramount.

However, the i5-13400T is the winner for desktop and power-sensitive deployments. Its 35-watt TDP is less than a quarter of the EPYC’s, making it drastically easier to cool and power. Its integrated graphics eliminate the need for a discrete GPU in basic systems. Its higher boost clock of 4.40 GHz and support for both DDR4 and DDR5 give it flexibility in consumer builds. Its higher Geekbench scores and higher average benchmark score (5210 vs 5109) suggest it handles general-purpose applications more effectively outside of Cinebench. The i5-13400T also launched at a much lower MSRP of $221 compared to the EPYC’s $575. For a workstation that prioritizes energy efficiency, modern platform features, and software compatibility with desktop chipsets, the i5-13400T is the data-backed choice. For a server that prioritizes raw throughput, memory bandwidth, and ECC reliability, the EPYC 7262 is unambiguously superior.
