AMD EPYC 7502P vs Intel Core i7-3770 Comparison

Head-to-Head Benchmarks

The benchmark data shows a complete sweep for the AMD EPYC 7502P, winning all eight head-to-head comparisons. The most extreme margins appear in the Cinebench suite, where the EPYC 7502P consistently delivers roughly seven times the performance of the Intel Core i7-3770. In Cinebench R15 multi-core, the EPYC 7502P scores 4374 against 549, a delta of 696.7%. The single-core result in the same test shows 617 versus 77, a 701.3% advantage. These are not incremental gains; they represent a generational chasm in compute throughput.

Cinebench R20 follows the same pattern. The multi-core score of 18225 for the EPYC 7502P dwarfs the 2289 of the Core i7-3770, with a 696.2% delta. Single-core R20 shows 2572 versus 322, a 698.8% gap. Cinebench R23 multi-core continues the trend: 43395 against 5450, again a 696.2% delta, while single-core R23 records 6126 versus 769, a 696.6% margin. The consistency of these deltas across R15, R20, and R23 suggests the performance ratio is stable regardless of the workload intensity or rendering complexity within the Cinebench family.

Geekbench tells a slightly different story. The multi-core test shows the EPYC 7502P at 7822 versus 2705 for the Core i7-3770, a 189.2% lead. This is still a decisive victory, but the margin is far smaller than in Cinebench. The single-core Geekbench result narrows further: 963 versus 816, an 18% advantage for the EPYC 7502P. That single-core delta is the closest any benchmark comes to a competitive race. The Core i7-3770, with its higher base clock of 3.40 GHz and boost of 3.90 GHz, is clearly more competitive in lightly threaded workloads, but the EPYC 7502P still wins outright.

The data indicates that the EPYC 7502P is not merely faster in aggregate; it is faster in every measured category, from heavily parallel rendering to single-threaded integer tasks. The 18% single-core Geekbench gap is notable because it shows the Zen 2 architecture holds its own even when core count is irrelevant. Meanwhile, the 696% to 701% margins in Cinebench reflect the 32-core, 64-thread configuration of the EPYC 7502P overwhelming the 4-core, 8-thread Core i7-3770 in multithreaded workloads.

FAQ

Q: Which CPU wins the majority of head-to-head benchmark comparisons?

A: The AMD EPYC 7502P wins all eight head-to-head comparisons across Cinebench R15, R20, R23, and Geekbench tests. The Intel Core i7-3770 does not win a single recorded benchmark in this comparison.

Q: How large is the multi-core performance gap in Cinebench R23?

A: In Cinebench R23 multi-core, the EPYC 7502P scores 43395 while the Core i7-3770 scores 5450, resulting in a 696.2% delta in favor of the EPYC 7502P.

Q: Is the single-core performance difference smaller than the multi-core difference?

A: Yes. In Geekbench single-core, the EPYC 7502P leads by only 18% (963 versus 816). In Cinebench R15 single-core, however, the lead is 701.3% (617 versus 77), so the gap varies significantly by benchmark.

Q: What are the average benchmark scores for each CPU?

A: The EPYC 7502P has an average benchmark score of 10512, while the Core i7-3770 has an average benchmark score of 9706. Both CPUs sit at the 66th percentile versus all CPUs in the database.

Q: Does the Core i7-3770 have any benchmark where it wins?

A: No. The recorded data shows zero wins for the Core i7-3770 across the eight head-to-head tests. The closest result is Geekbench single-core, where it trails by 18%.

Q: How does the EPYC 7502P compare to its nearest rivals?

A: The EPYC 7502P trails the AMD EPYC 7D12 by 0.3% and the Intel Core i7-4790 by 0.4% in average score, while leading the Intel Xeon W-3175X by 1.4% and the Intel Xeon Gold 6338N by 1.6%.

The Verdict

The data points to a clear conclusion for different user profiles. The AMD EPYC 7502P is the only choice for multithreaded server or workstation workloads. Its 32 cores and 64 threads, combined with 128 MB of shared L3 cache and eight-channel DDR4 memory support, deliver 696.2% to 696.7% advantages in Cinebench multi-core tests. The recorded data shows its average benchmark score of 10512 places it near the top of its immediate rival group, within 0.4% of the Intel Core i7-4790 and 0.3% of the AMD EPYC 7D12.

The Intel Core i7-3770 is an end-of-life desktop part with a 77 W TDP and integrated Intel HD 4000 graphics. Its average benchmark score of 9706 is competitive with its own nearest rivals, including a 0.2% lead over the Intel Core i5-1035G1 and a 2.2% lead over the Intel Core i7-7700HQ. For legacy desktop applications, or systems where the integrated graphics and lower power draw are priorities, the Core i7-3770 remains functional, but it cannot compete with the EPYC 7502P in any measured metric.

The 18% single-core Geekbench gap is the only area where the Core i7-3770 approaches parity. That result, however, does not change the overall assessment: the EPYC 7502P is faster in every recorded test, with margins ranging from 18% to 701.3%. For anyone choosing between these two based on benchmark data alone, the EPYC 7502P is the superior processor in all measured scenarios.

Specification Differences

The two processors differ in nearly every fundamental specification. The EPYC 7502P has 32 cores and 64 threads, while the Core i7-3770 has 4 cores and 8 threads. Base clocks differ: the EPYC 7502P runs at 2.50 GHz, the Core i7-3770 at 3.40 GHz. Boost clocks are 3.35 GHz versus 3.90 GHz, favoring the Intel part in raw clock speed. TDP is another major divergence: 180 W for the EPYC 7502P, 77 W for the Core i7-3770.

Sockets are incompatible: the EPYC 7502P uses AMD Socket SP3, the Core i7-3770 uses Intel Socket 1155. Memory support differs completely, with the EPYC 7502P using DDR4 across an eight-channel bus delivering 204.8 GB/s bandwidth, while the Core i7-3770 uses DDR3 on a dual-channel bus at 25.6 GB/s. ECC memory is supported on the EPYC 7502P but not on the Core i7-3770. PCIe generation also differs: Gen 4 on the EPYC 7502P versus Gen 3 with 16 lanes on the Core i7-3770. The Core i7-3770 includes integrated Intel HD 4000 graphics; the EPYC 7502P has no integrated graphics. The Core i7-3770 has a launch MSRP of $278.

Architecture Differences

The architectural gap is substantial. The EPYC 7502P is built on AMD's Zen 2 architecture, codenamed Rome, part of the EPYC 7002 series. The Core i7-3770 uses Intel's Ivy Bridge architecture. The process nodes reflect their eras: the EPYC 7502P is fabricated on a 7 nm process at TSMC, while the Core i7-3770 uses Intel's 22 nm process. Transistor counts differ accordingly: 3,800 million for the EPYC 7502P versus 1,400 million for the Core i7-3770. Die sizes are 74 mm² for the EPYC 7502P and 160 mm² for the Core i7-3770, an inversion driven by the chiplet design of the Rome architecture.

Cache hierarchies are also different. The EPYC 7502P has 96 KB of L1 per core, 512 KB of L2 per core, and 128 MB of shared L3. The Core i7-3770 has 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3. The 16x difference in L3 capacity aligns with the 8x difference in core count, but the per-core L3 allocation still favors the EPYC 7502P. Market segments diverge as well: the EPYC 7502P targets server and workstation deployments, while the Core i7-3770 is a desktop processor. Production status also differs, with the EPYC 7502P listed as active and the Core i7-3770 as end-of-life.
