CPU Comparison

This comparison pairs two processors built for entirely different worlds: the Intel Core 3 100U, a 15-watt mobile chip for thin-and-light laptops, and the AMD EPYC 75F3, a 280-watt server behemoth with 32 cores. The data shows a clean sweep in raw performance for the EPYC, but the story is more nuanced when you consider the use cases each part was designed to serve. The Core 3 100U is about efficiency and everyday responsiveness, while the EPYC 75F3 is about sheer throughput in dense, multi-threaded server workloads. Benchmark results confirm that these are not competitors in any practical sense, yet the numbers reveal exactly how far apart they are.

Where Each One Wins

The AMD EPYC 75F3 wins every single benchmark in the head-to-head comparison, taking all six Cinebench tests with a consistent delta of -80.6% against the Intel part. This is a processor built for multi-threaded, high-core-count workloads like database hosting, virtualization, and heavy scientific computing. Its 32 cores and 64 threads provide a massive parallel execution capability that the Intel Core 3 100U cannot match. The EPYC’s wins are not marginal; they are categorical, with multi-core scores that are roughly five times higher across all Cinebench versions.

The Intel Core 3 100U, by contrast, wins in the context of its intended mobile segment. It is not designed to compete on raw compute but to deliver a balanced experience in a low-power envelope. Its 15-watt TDP makes it suitable for fanless or lightly cooled designs, and its integrated UHD Graphics 64EU provides a display output without a discrete GPU. In single-threaded tasks, the Core 3 100U’s boost clock of 4.70 GHz is high, though it still loses to the EPYC’s 4.00 GHz boost in the actual benchmark data. The Core 3 100U’s wins are in portability and power efficiency, not in performance metrics.

Architecture Differences

The architectural gap is enormous. The Intel Core 3 100U uses Raptor Lake-U, built on Intel’s 10 nm process, with 6 cores and 8 threads. It has a base clock of 1.20 GHz and a boost clock of 4.70 GHz. Its cache layout includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3. The memory support covers DDR4 and DDR5 in a dual-channel configuration, with no ECC support. The PCIe interface is Gen 4 with 8 lanes from the CPU. The integrated graphics are UHD Graphics 64EU. This is a mobile part, soldered to Intel BGA 1744, with a launch MSRP of $426.

The AMD EPYC 75F3 uses Zen 3 architecture (codename Milan), built on TSMC’s 7 nm process. It has 32 cores and 64 threads, with a base clock of 2.95 GHz and a boost clock of 4.00 GHz. The cache hierarchy is different: 64 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3. Transistor count is 33,200 million across a die size of 8x 81 mm². Memory support is DDR4 only, but in an eight-channel configuration delivering 204.8 GB/s of bandwidth. ECC memory is supported. The PCIe interface is Gen 4 with 128 lanes. There is no integrated graphics. It is a server/workstation part for AMD Socket SP3, with a launch MSRP of $4860.

Head-to-Head Benchmarks

The head-to-head data is stark. In Cinebench R15 multi-core, the EPYC 75F3 scores 5526 against the Core 3 100U’s 1070, a delta of -80.6%. The single-core R15 test shows the EPYC at 780 versus 150, again -80.6%. Moving to Cinebench R20, the multi-core result is 23028 for the EPYC and 4462 for Intel, with single-core at 3250 versus 629. The pattern repeats in Cinebench R23: multi-core 54829 versus 10624, and single-core 7740 versus 1499. Every test shows the EPYC winning by the same -80.6% margin, indicating that the performance gap is proportional across all workload types.

These deltas are not close calls. The EPYC’s single-core advantage alone is larger than the Intel chip’s total multi-core score. For instance, in Cinebench R23, the EPYC’s single-core score of 7740 is nearly 73% of the Intel Core 3 100U’s multi-core score of 10624. This means that a single EPYC core is almost as fast as the entire Intel processor in a multi-threaded render. The data suggests that for any compute-heavy task, the EPYC is in a different league. The Intel part’s only saving grace is its power draw and form factor, but those are not reflected in benchmark scores.

FAQ

Q: Which processor has a higher boost clock?

A: The Intel Core 3 100U has a boost clock of 4.70 GHz, while the AMD EPYC 75F3 has a boost clock of 4.00 GHz. Despite the lower peak frequency, the EPYC wins all single-core benchmarks by a wide margin.

Q: Can the Intel Core 3 100U be used in a server environment?

A: The data shows it lacks ECC memory support and has only 8 PCIe Gen 4 lanes, compared to the EPYC’s 128 lanes and ECC support. It is classified as a mobile segment part, so server workloads would be severely limited.

Q: What is the memory bandwidth difference?

A: The AMD EPYC 75F3 supports eight-channel DDR4 with a bandwidth of 204.8 GB/s. The Intel Core 3 100U supports dual-channel DDR4/DDR5, but no bandwidth figure is listed in the data.

Q: How many more cores does the EPYC have?

A: The EPYC 75F3 has 32 cores and 64 threads, compared to the Intel Core 3 100U’s 6 cores and 8 threads. That is a 26-core and 56-thread difference.

Q: Does the Intel part have integrated graphics?

A: Yes, it has UHD Graphics 64EU. The AMD EPYC 75F3 has no integrated graphics, which is typical for server parts that rely on discrete GPUs or no display output.

Q: Which part has a higher average benchmark score?

A: The Intel Core 3 100U has an average benchmark score of 16148, while the AMD EPYC 75F3 has an average of 15859. This is surprising given the EPYC’s dominance in Cinebench, but the Intel part’s PassMark scores (e.g., 136497 in data compression) boost its average.

The Verdict

The verdict is clear: choose the AMD EPYC 75F3 if your workload requires massive multi-threading, high memory bandwidth, or ECC reliability. The data shows it is 80.6% faster in every Cinebench test, with a 256 MB L3 cache and 204.8 GB/s bandwidth that are essential for server and workstation tasks. Its 32 cores and 64 threads make it a powerhouse for virtualization, rendering, or any parallel compute job. The launch MSRP of $4860 reflects its enterprise positioning.

Choose the Intel Core 3 100U if you need a low-power mobile processor with integrated graphics and a small footprint. Its 15-watt TDP and 4.70 GHz boost clock are suited for laptops where battery life and portability matter more than raw compute. The integrated UHD Graphics 64EU eliminates the need for a discrete GPU in basic systems. Its average benchmark score of 16148 is actually higher than the EPYC’s 15859, driven by strong PassMark results in data compression (136497) and integer math (39580), but those numbers do not translate to server-class performance.
