AMD EPYC 9454P vs Intel Core i5-12600T Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep in favor of the AMD EPYC 9454P across the Cinebench suite. In Cinebench R23 multi-core, the EPYC scores 81,492 against the Intel Core i5-12600T's 14,822, a delta of -81.8% from the Intel part's perspective. That same gap repeats in Cinebench R20 multi-core (34,226 vs 6,225) and Cinebench R15 multi-core (8,214 vs 1,494), each showing the identical -81.8% margin. The pattern holds for single-core Cinebench runs: R23 single-core sees the EPYC at 11,504 versus 2,092, and R15 single-core shows 1,159 versus 210, again both at -81.8%. The only Intel win among the eight shared benchmarks comes in Geekbench single-core, where the i5-12600T scores 2,048 against the EPYC's 2,011, a narrow 1.8% advantage. Geekbench multi-core, however, reverses that entirely: the EPYC posts 19,941 versus 7,374, giving a -63% delta for the Intel chip.

The magnitude of these deltas is worth pausing on. A -81.8% delta means the EPYC is roughly 5.5 times faster in those workloads, not merely a step ahead. The single-core Cinebench results are surprising given the EPYC's lower boost clock of 3.80 GHz versus the i5's 4.60 GHz, yet the data consistently favors the AMD part. The Intel processor's single Geekbench win is real but small, 1.8%, and it does not offset the multi-core dominance. Across the eight head-to-head tests, the EPYC claims seven wins and the Intel part claims one. The average benchmark score database entries put the i5-12600T at 20,917 and the EPYC at 20,422, which seems counterintuitive given the head-to-head results, but that average includes many non-overlapping tests where the Intel part has additional PassMark scores. The nearest rivals for the i5-12600T include the AMD Ryzen 5 PRO 4655GE at 20,900 (0.1% delta) and the Intel Core Ultra 7 268V at 20,897 (0.1% delta), while the EPYC's nearest rivals include the AMD Ryzen 5 8500G at 20,425 (0% delta) and the Intel Core Ultra 7 258V at 20,454 (-0.2% delta).

Where Each One Wins

The AMD EPYC 9454P owns every multi-threaded rendering workload in the shared test set. Cinebench R15, R20, and R23 multi-core all show the same -81.8% delta, meaning the EPYC's 48 cores and 96 threads simply overpower the i5-12600T's 6 cores and 12 threads in heavily parallel workloads. The EPYC also wins Geekbench multi-core by a -63% delta, which reflects a broader set of integer, floating-point, and memory operations. If the task is video rendering, 3D modeling, compilation, or any workload that scales across cores, the data points squarely at the EPYC. The EPYC's single-core Cinebench wins are less expected but still decisive: -81.8% in all three Cinebench single-core tests. That suggests the Zen 4 architecture's per-thread efficiency, despite a lower boost clock, outperforms the Alder Lake core in these specific rendering benchmarks.

The Intel Core i5-12600T has exactly one head-to-head win: Geekbench single-core at 1.8% ahead. That is a narrow margin, likely reflecting the i5's higher 4.60 GHz boost clock and the UHD Graphics 770's presence, though the benchmark itself is CPU-focused. For users who prioritize single-threaded responsiveness in everyday applications, the i5-12600T holds a slight edge in this one test, but it is not a broad single-core victory. The i5 also has a significant advantage in power consumption, with a 35 W TDP versus the EPYC's 290 W, which is a qualitative difference in operating requirements. However, the benchmark data does not include any power efficiency tests, so that remains a specification observation, not a measured performance win.

Architecture Differences

The Intel Core i5-12600T uses the Alder Lake architecture on a 10 nm process, built by Intel, with a die size of 163 mm². The AMD EPYC 9454P uses Zen 4, codenamed Genoa, on a 5 nm process from TSMC, with a die size listed as 8x 72 mm² and 52,560 million transistors. The transistor count difference is enormous, but the database does not list a transistor figure for the Intel part, so direct comparison is not possible. The core counts diverge sharply: 6 cores and 12 threads for Intel, 48 cores and 96 threads for AMD. Cache hierarchies also differ. The i5-12600T has 80 KB L1 per core, 1.25 MB L2 per core, and 18 MB shared L3. The EPYC has 64 KB L1 per core, 1 MB L2 per core, and 256 MB shared L3. The EPYC's L3 cache is more than 14 times larger, which helps in data-heavy server workloads. The i5 has integrated graphics (UHD Graphics 770), while the EPYC has none. The EPYC supports ECC memory; the i5 does not. Memory channels differ as well: the i5 uses dual-channel DDR4 or DDR5, while the EPYC uses twelve-channel DDR5 with a listed memory bandwidth of 460.8 GB/s. The i5's memory bandwidth is not listed, so no numeric comparison is possible, but twelve-channel versus dual-channel is a structural advantage for the EPYC. PCIe lanes also differ: the i5 has 20 Gen 5 lanes from the CPU, the EPYC has 128 Gen 5 lanes, a 6.4x difference in available I/O.

Specification Differences

The two processors differ in nearly every specification field. The i5-12600T has a base clock of 2.10 GHz and a boost clock of 4.60 GHz; the EPYC has a base clock of 2.75 GHz and a boost clock of 3.80 GHz. TDP is 35 W for the Intel part and 290 W for the AMD part. Sockets are incompatible: Intel Socket 1700 versus AMD Socket SP5. Process nodes are 10 nm (Intel) versus 5 nm (TSMC). The EPYC has a listed release date of 2022-11-09; the i5 has no release date in the database. Launch MSRP is $223 for the i5 and $4598 for the EPYC. The i5's die size is 163 mm²; the EPYC's is 8x 72 mm². Cache per core differs (80 KB L1 and 1.25 MB L2 for Intel; 64 KB L1 and 1 MB L2 for AMD), and L3 shared cache is 18 MB versus 256 MB. Memory support is DDR4 and DDR5 for Intel, DDR5 only for AMD, with dual-channel versus twelve-channel memory buses. ECC memory is false for Intel and true for AMD. PCIe is Gen 5 with 20 lanes versus Gen 5 with 128 lanes. Integrated graphics are present on the Intel part only. Neither processor has an unlocked multiplier. Part numbers are SRL5U for Intel and 100-100000873 for AMD. The market segments are Desktop for Intel and Server/Workstation for AMD.

The Verdict

The benchmark data is unambiguous for multi-threaded and most single-threaded workloads: the AMD EPYC 9454P is the dominant part in every shared Cinebench test, with identical -81.8% deltas across R15, R20, and R23, and a -63% delta in Geekbench multi-core. Users running rendering, compilation, or any scalable parallel workload should select the EPYC based on the recorded scores. The EPYC also wins all three Cinebench single-core tests, meaning even in lightly threaded rendering tasks, the Zen 4 architecture outperforms the Alder Lake part despite a lower boost clock. The Intel Core i5-12600T's only measured win is Geekbench single-core at 1.8%, which is a narrow margin and likely not decisive for any real-world application. The i5's advantages are qualitative rather than benchmark-based: a 35 W TDP versus 290 W, integrated graphics, and a lower launch MSRP of $223 versus $4598. The EPYC's advantages include ECC memory support, twelve-channel DDR5 memory with 460.8 GB/s bandwidth, 128 PCIe Gen 5 lanes, and 256 MB L3 cache. For a server or workstation role, the EPYC is the clear choice. For a desktop role with modest power constraints and no need for ECC or massive I/O, the i5-12600T suffices, but the head-to-head data shows the EPYC wins 7 out of 8 tests. The verdict from the measurements: the EPYC 9454P is the superior processor in nearly every measured category, with the i5-12600T retaining only a slim Geekbench single-core edge and a large power consumption advantage.
