AMD EPYC 7473X vs Intel Core i7-8750H Comparison

Where Each One Wins

The benchmark data paints an unusually one-sided picture. Across every recorded Cinebench test, the AMD EPYC 7473X claims victory, leaving the Intel Core i7-8750H with zero wins in the head-to-head comparison. The database records 6 wins for the EPYC part and 0 for the mobile Intel chip. This is not a contest of close margins; it is a systematic gap that appears in both single-threaded and multi-threaded workloads.

The use-case split is therefore less about which processor wins a given task and more about what each processor is designed to accomplish. The EPYC 7473X belongs to the EPYC 7003 series, a server and workstation part built for sustained, high-throughput compute. Its 24 cores and 48 threads give it a natural home in rendering farms, database servers, and scientific computing where parallel workloads scale across many threads. The Core i7-8750H, by contrast, is a mobile part from the Coffee Lake-H generation, aimed at laptops where thermal and power envelopes are tight. It is an end-of-life product, whereas the EPYC remains active in production.

The data suggests that for any task measured by Cinebench, the EPYC 7473X is categorically faster. But the i7-8750H does retain one structural advantage that the benchmark suite does not capture directly: it includes integrated UHD 630 graphics, while the EPYC has no integrated graphics at all. That makes the Intel part viable in systems without a discrete GPU, a scenario the server chip cannot serve.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD EPYC 7473X uses Zen 3 architecture under the Milan-X codename, built on a 7 nm process at TSMC. The Intel Core i7-8750H uses Coffee Lake architecture, specifically Coffee Lake-H, built on Intel's 14 nm process. The process node gap alone, 7 nm versus 14 nm, explains much of the efficiency and density difference between the two.

Core counts diverge sharply: 24 cores and 48 threads for the EPYC, versus 6 cores and 12 threads for the Intel part. Clock speeds tell a more nuanced story. The EPYC has a base clock of 2.80 GHz and a boost clock of 3.70 GHz. The i7-8750H starts at 2.20 GHz but boosts to 4.10 GHz, a higher peak frequency. That higher boost clock on the Intel chip does not translate into benchmark wins, however, suggesting the EPYC's core count and cache hierarchy overwhelm the mobile part even at lower clocks.

Cache is where the EPYC 7473X delivers its most dramatic advantage. The EPYC features 64 KB of L1 per core, 512 KB of L2 per core, and a massive 768 MB of shared L3 cache. The Intel part has 64 KB of L1 per core, 256 KB of L2 per core, and just 12 MB of shared L3. That 768 MB figure is a 64x difference in L3 capacity, a figure that likely drives the EPYC's dominance in repeated, cache-resident workloads.

Memory support also separates the two. The EPYC supports DDR4 with an eight-channel memory bus and 204.8 GB/s of bandwidth, plus ECC memory. The Intel mobile chip supports DDR4 but the database records no memory bus width, no bandwidth figure, and no ECC support. The EPYC also brings PCIe Gen 4 with 128 lanes (CPU only), while the Intel part has no recorded PCIe specification. Socket types differ as expected: AMD Socket SP3 for the server chip, Intel BGA 1440 for the mobile part. The EPYC lists a transistor count of 33,200 million across 8x 81 mm² dies, while the Intel chip has no transistor figure recorded but a die size of 149 mm².

Head-to-Head Benchmarks

Every recorded head-to-head benchmark shows the AMD EPYC 7473X winning by a factor of roughly five to six. The margins are consistent, which suggests a stable performance gap rather than a workload-specific quirk.

In Cinebench R15 multicore, the EPYC scores 5078 against 834 for the Intel chip, a delta of 508.9%. That is a sixfold advantage. Single-core in R15 tells the same story: 716 versus 117, a 512% delta. The EPYC wins by a slightly larger percentage in single-core than in multicore, which is notable because single-threaded performance is often considered an Intel strength. Here, the EPYC's Zen 3 cores simply outrun the older Coffee Lake cores.

Cinebench R20 multicore shows 21162 for the EPYC versus 3475 for the i7-8750H, a 509% delta. Single-core R20: 2987 versus 490, a 509.6% delta. The consistency continues in Cinebench R23, where the EPYC posts 50388 multicore against 8274, and 7113 single-core against 1168, both at 509% deltas.

The i7-8750H has additional recorded benchmarks in the database that the EPYC does not share, including Geekbench and Passmark tests. The Intel chip scores 4978 in Geekbench multicore and 1309 in single-core, with Passmark results ranging from 27 in find prime numbers to 139418 in data compression. These numbers cannot be compared directly to the EPYC since the server chip lacks those same test scores in the database, but they provide context for where the mobile part sits in absolute terms.

The average benchmark score further illustrates the gap: the EPYC averages 14574, while the i7-8750H averages 13868. Interestingly, the i7-8750H's nearest rivals include the AMD EPYC 7443 (13936, delta -0.5%), AMD Ryzen Threadripper PRO 3975WX (13786, delta 0.6%), Intel Core 3 304 (13745, delta 0.9%), and Intel Core i5-10400 (14037, delta -1.2%). The EPYC 7473X's nearest rivals are quite different: Intel Xeon 6315P (14574, delta 0%), AMD Ryzen 5 5500U (14589, delta -0.1%), Intel Core i5-9600K (14605, delta -0.2%), and AMD Ryzen 3 4100 (14505, delta 0.5%). Both chips sit near the 68th to 69th percentile of all CPUs, with the EPYC at 69 and the Intel at 68.

The Verdict

The data directs different buyers to different chips, but the direction is clear. The AMD EPYC 7473X is the choice for anyone running Cinebench-style parallel workloads in a server or workstation context. Its 24 cores, 48 threads, 768 MB of L3 cache, and eight-channel DDR4 memory with 204.8 GB/s bandwidth make it a purpose-built compute engine. The 509% multicore lead in Cinebench R23 over the i7-8750H is not a marginal edge; it is a generational and segment-defining gap. Its active production status and launch MSRP of $3900 place it as a current, high-end server part.

The Intel Core i7-8750H is a different animal entirely. As a mobile, end-of-life processor from 2018, it is not competitive with the EPYC on any recorded benchmark. Its 45 W TDP, integrated UHD 630 graphics, and BGA 1440 socket suit laptops and compact systems. It wins no head-to-head tests in the database, and its higher boost clock of 4.10 GHz does not overcome the core-count and cache deficit.

The percentile data shows both chips near each other in the overall CPU population, 69th for the EPYC and 68th for the Intel, which reflects the database's broad mix of desktop, mobile, and server parts rather than a head-to-head equivalence. The nearest rivals for each chip reinforce that they compete in different pools: the EPYC sits alongside the Xeon 6315P and desktop Core i5-9600K, while the i7-8750H sits near the EPYC 7443 and Threadripper PRO 3975WX. In short, pick the EPYC 7473X for raw compute density and server workloads; pick the i7-8750H only if the requirement is a mobile form factor with integrated graphics and low power. The benchmark data offers no other reason to choose the Intel part.
