AMD EPYC 7451 vs Intel Core i7-12700T Comparison

Head-to-Head Benchmarks

The recorded data presents a remarkably consistent picture: the AMD EPYC 7451 wins every single head-to-head benchmark against the Intel Core i7-12700T, with a narrow delta range between 13.3% and 13.6% across all six Cinebench tests. This uniformity suggests the performance gap is structural rather than workload-dependent.

In Cinebench R15 multi-core, the EPYC 7451 scores 2061 against 1815 for the i7-12700T, a 13.6% advantage. The single-core R15 result follows the same pattern: 290 versus 256, a 13.3% delta. Moving to Cinebench R20, the multi-core gap holds at 8589 versus 7565 (13.5%), while single-core shows 1212 versus 1067 (13.6%). The latest Cinebench R23 tests confirm the trend: 20450 versus 18012 multi-core (13.5%) and 2887 versus 2542 single-core (13.6%).

The near-identical delta percentages across every test are striking. Whether the workload is single-threaded or multi-threaded, the EPYC 7451 maintains essentially the same proportional lead. This indicates the advantage comes from fundamental architectural efficiency rather than core count alone.

The i7-12700T does have additional benchmark data in the database, including Geekbench scores of 11502 multi-core and 2089 single-core, but no comparable Geekbench result exists for the EPYC 7451, so direct comparison in that test is not possible from the available measurements.

When placed against their respective nearest rivals, both processors sit in similar competitive positions. The EPYC 7451 has an average benchmark score of 5915, placing it 0% away from the Intel Core i9-9920X (5917), 1.2% behind the Intel Xeon W-2170B (5985), 1.7% ahead of the AMD EPYC 7401P (5814), and 1.9% ahead of the Intel Xeon E-2388G (5805). The i7-12700T averages 5606, sitting 0.1% behind the AMD Ryzen 7 PRO 3700 (5610), 0.1% ahead of the Intel Atom x7433RE (5601), 0.3% ahead of the Intel Core i9-11900KB (5587), and 0.8% ahead of the Intel Celeron G6900 (5561). Both processors occupy the 61st percentile among all CPUs in the database.

Where Each One Wins

The benchmark data shows a complete sweep for the AMD EPYC 7451, meaning there is no test category where the Intel Core i7-12700T comes out ahead. However, the nature of the wins differs by workload type.

For multi-core rendering tasks, the EPYC 7451's advantage is substantial in absolute terms. The R23 multi-core gap of 2438 points (20450 versus 18012) represents a meaningful difference for long-running compute jobs. The R20 multi-core delta of 1024 points (8589 versus 7565) reinforces this picture. These are not marginal wins; they reflect the EPYC 7451's 24 cores and 48 threads against the i7-12700T's 12 cores and 20 threads.

The single-core results tell a more nuanced story. While the EPYC 7451 still wins, the absolute deltas are smaller: 34 points in R15 (290 versus 256), 145 points in R20 (1212 versus 1067), and 345 points in R23 (2887 versus 2542). The percentage gaps remain around 13.3% to 13.6%, but in raw terms, these are closer contests. A user moving from the i7-12700T to the EPYC 7451 would notice the single-core improvement less than the multi-core jump.

The i7-12700T does offer features the EPYC 7451 lacks, such as integrated graphics (UHD Graphics 770) and support for both DDR4 and DDR5 memory, but these do not translate into benchmark wins in the recorded Cinebench data. The EPYC 7451 counters with eight-channel memory support and a memory bandwidth of 170.6 GB/s, though the i7-12700T has no recorded memory bandwidth figure for comparison.

The Verdict

The data points to a clear choice for users prioritizing raw compute performance: the AMD EPYC 7451 wins all six recorded benchmarks with a consistent 13.3% to 13.6% advantage. The 24-core, 48-thread configuration with 180W TDP delivers higher scores across every Cinebench iteration, from the older R15 to the current R23.

However, the Intel Core i7-12700T serves a different purpose entirely. Its 35W TDP, integrated graphics, and desktop-oriented feature set make it suitable for systems where power efficiency and compactness matter more than peak throughput. The 12-core, 20-thread design with a 4.70 GHz boost clock (against the EPYC's 3.20 GHz boost) still delivers competitive scores, sitting at the same 61st percentile as the EPYC.

For server and workstation workloads, the EPYC 7451's eight-channel memory bus, ECC memory support, and 64 MB shared L3 cache align with its market segment. The i7-12700T, with dual-channel memory and no ECC support, targets desktop use cases where those enterprise features are unnecessary.

The EPYC 7451 also offers an unlocked multiplier, while the i7-12700T is locked. The EPYC's 180W TDP versus the i7's 35W TDP reflects the trade-off between raw performance and power consumption. The database shows the EPYC 7451's launch date as June 28, 2017, while the i7-12700T has no recorded release date, though its Core 12th Gen series places it in a later generation.

The base clock figures appear in different units in the database: the EPYC 7451 lists 2.30 GHz, while the i7-12700T lists 1400.00 MHz, which the data records as its base frequency. The boost clocks show the i7-12700T reaching 4.70 GHz against the EPYC's 3.20 GHz, yet the EPYC still wins single-core benchmarks, indicating architectural efficiency differences beyond clock speed.
