AMD EPYC 7543 vs Intel Core i7-9750H Comparison

Head-to-Head Benchmarks

The benchmark data tells a remarkably one-sided story. Across every Cinebench workload recorded in the database, the AMD EPYC 7543 dominates the Intel Core i7-9750H by a margin that is difficult to overstate. The smallest gap appears in Cinebench R15 single-core, where the EPYC scores 761 against the Intel chip's 127, a 499.2% advantage. The multicore results tell the same tale: in Cinebench R15 multicore, the EPYC posts 5393 versus 904, a 496.6% lead. Those are not incremental improvements; they represent a fundamentally different performance class.

Moving to newer rendering workloads, the pattern holds exactly. Cinebench R20 multicore shows the EPYC at 22473 and the i7-9750H at 3768, a 496.4% difference. The single-core R20 result is similar, 3172 versus 531, a 497.4% gap. Cinebench R23, the most demanding of the tested suite, reinforces the trend: the EPYC scores 53509 multicore and 7554 single-core, while the Intel part manages 8973 and 1266 respectively, deltas of 496.3% and 496.7%. Every recorded comparison, all six head-to-head benchmarks, goes to the AMD processor.

What makes this interesting is not just the magnitude but the consistency. The deltas cluster tightly between 496.3% and 499.2%, suggesting the performance gap is structural rather than workload-specific. Whether the test stresses one thread or all available threads, the EPYC 7543 maintains roughly a five-to-one advantage. For a builder comparing a server/workstation processor to a mobile chip, this is the expected shape of the data, but the uniformity is still striking.

The average benchmark scores in the database confirm the broader picture. The EPYC 7543 carries an average score of 15477, while the i7-9750H averages 14886. The EPYC lands 0.7% above the Intel Core 5 211TE and 1.3% below the AMD Ryzen 3 7440U in its nearest rival group. The i7-9750H sits 0.2% above the Intel Core i3-10320 and 0.9% below the Intel Core i3-1315U. Both processors occupy the 69th percentile among all CPUs, which places them in similar company on average, but that average hides the extreme divergence in the Cinebench tests, where the EPYC's 32 cores are simply overwhelming.

The Verdict

The verdict here is straightforward: pick the AMD EPYC 7543 if your work involves sustained multi-threaded rendering, compilation, or server-side workloads, and pick the Intel Core i7-9750H only if you need a low-power mobile processor and the EPYC is not physically an option. The data does not support any other conclusion.

The EPYC 7543 wins all six recorded head-to-head benchmarks, with deltas between 496.3% and 499.2%. That is not a close contest by any reasonable interpretation. The Intel chip's best showing, relatively speaking, is in Cinebench R23 multicore, where it still trails by 496.3%. The EPYC offers 32 cores and 64 threads, an eight-channel memory bus with 204.8 GB/s of bandwidth, and 256 MB of shared L3 cache. The i7-9750H counters with 6 cores, 12 threads, dual-channel memory at 42.7 GB/s, and 12 MB of L3 cache. There is no benchmark category in the recorded data where the Intel part wins.

That said, the i7-9750H is a mobile processor with a 45 W TDP, while the EPYC is a 225 W server part. They are not competing for the same socket, the same chassis, or the same use case. The Intel chip fits in a laptop; the EPYC requires a server motherboard. If your constraint is a laptop, the i7-9750H is the only one of the two that physically fits. If your constraint is raw computing throughput, the EPYC is the only rational choice. The database does not record a single metric where the Intel chip is preferable on performance grounds.

Architecture Differences

The two processors come from different eras and different design philosophies. The AMD EPYC 7543 belongs to the EPYC 7003 series, built on Zen 3 architecture with the codename Milan. It uses a 7 nm process from TSMC, packs 33,200 million transistors across 8x 81 mm² dies, and targets the server/workstation market segment. It was released on 2021-03-14 and remains in active production. The launch MSRP is $3761. The multiplier is locked, which is typical for server parts.

The Intel Core i7-9750H uses Coffee Lake architecture, specifically the Coffee Lake-HR refresh, built on Intel's 14 nm process with a 149 mm² die. It is a mobile part, released on 2019-04-22, and is now end-of-life. It integrates UHD 630 graphics, which the EPYC lacks entirely. The Intel chip's transistor count is not recorded in the database, but the die size and process node differences are substantial.

Cache configurations differ sharply. The EPYC 7543 provides 64 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3. The i7-9750H also has 64 KB of L1 per core, but only 256 KB of L2 per core and 12 MB of shared L3. That 256 MB L3 pool is a defining feature of the EPYC, enabling large working sets to stay on-die. The Intel part's smaller cache reflects its mobile, power-constrained design.

Memory support diverges as well. Both support DDR4, but the EPYC runs an eight-channel memory bus with 204.8 GB/s of bandwidth and supports ECC memory. The i7-9750H is dual-channel with 42.7 GB/s and no ECC support. PCIe connectivity also differs: the EPYC offers Gen 4 with 128 lanes (CPU only), while the Intel chip is limited to Gen 3. For server workloads that depend on memory bandwidth or high lane counts for expansion, these are decisive differences.

Clock speeds tell an interesting story. The Intel chip has a higher boost clock at 4.50 GHz versus the EPYC's 3.70 GHz, and a slightly lower base clock at 2.60 GHz versus 2.80 GHz. Yet in single-core Cinebench tests, the EPYC still wins by roughly 497%. This suggests that the EPYC's architectural efficiency, larger cache, and memory bandwidth more than compensate for the Intel part's higher boost frequency. The i7-9750H's 45 W TDP versus the EPYC's 225 W TDP explains much of the clock advantage; a mobile chip can push a few cores high, but it cannot sustain the power draw of a server part.

Where Each One Wins

The AMD EPYC 7543 wins every recorded benchmark category. That is the short answer. The longer answer is about what those wins mean in practice. The EPYC's 32 cores and 64 threads make it a natural fit for Cinebench-style rendering workloads, where the R23 multicore score of 53509 demonstrates massive parallel throughput. The 256 MB of shared L3 cache and 204.8 GB/s of memory bandwidth support data-heavy server tasks, database workloads, and virtualization. The eight-channel memory bus and 128 PCIe Gen 4 lanes give it expansion headroom that a mobile chip cannot approach. The 7 nm process and active production status mean it remains a current, supportable platform.

The Intel Core i7-9750H wins in categories that are not captured by the benchmark data but are implicit in its specifications. It is a mobile processor with a 45 W TDP, which means it can operate in a laptop chassis with battery power and modest cooling. It has integrated UHD 630 graphics, so a discrete GPU is not strictly required for basic display output. Its 14 nm process and 149 mm² die are older, but the part is end-of-life, so it may be available in inexpensive used laptops. Its higher boost clock of 4.50 GHz suggests it can respond quickly to short bursts of single-threaded activity, even if the recorded Cinebench single-core scores do not reflect an advantage.

For a builder choosing between these two, the decision is not about which is better in a vacuum. It is about which fits the physical and power constraints of the build. The EPYC 7543 demands a server platform, 225 W of power delivery, and a chassis that can cool a large socketed processor. The i7-9750H is soldered to a motherboard via BGA 1440 and is designed for thin-and-light or mainstream laptops. If the task is rendering, compiling, or serving, the EPYC is the only choice. If the task is mobile computing, the i7-9750H is the only one that fits.

Specification Differences

The specification sheet shows a gulf between these two parts. The EPYC 7543 has 32 cores and 64 threads, while the i7-9750H has 6 cores and 12 threads. Base clocks are 2.80 GHz against 2.60 GHz, and boost clocks are 3.70 GHz against 4.50 GHz. TDP is 225 W versus 45 W. The socket differs completely: AMD Socket SP3 for the EPYC, Intel BGA 1440 for the i7. Process node is 7 nm (TSMC) versus 14 nm (Intel). The EPYC packs 33,200 million transistors across 8x 81 mm² dies; the i7 uses a single 149 mm² die with no recorded transistor count.

Cache is another clear differentiator. L1 is identical at 64 KB per core. L2 is 512 KB per core on the EPYC versus 256 KB per core on the i7. L3 is 256 MB shared on the EPYC versus 12 MB shared on the i7. Memory bus width is eight-channel versus dual-channel, with 204.8 GB/s versus 42.7 GB/s bandwidth. ECC is supported on the EPYC, not on the i7. PCIe is Gen 4 with 128 lanes on the EPYC, Gen 3 on the i7. The Intel part has integrated UHD 630 graphics; the EPYC has none.

Market positioning differs as well. The EPYC is a server/workstation part, released on 2021-03-14, still active, with a launch MSRP of $3761. The i7-9750H is a mobile part, released on 2019-04-22, end-of-life, with no recorded launch MSRP. Both have locked multipliers. The EPYC's part number is 100-000000345100-100000345WOF; the Intel part number is SRF6USRFCP. Every specification field where the two differ points in the same direction: the EPYC is designed for maximum throughput in a power-hungry server context, while the i7 is designed for efficiency and mobility in a constrained laptop chassis.
