AMD Ryzen 5 PRO 1500 vs Intel Core i7-5775C Comparison

The AMD Ryzen 5 PRO 1500 and Intel Core i7-5775C are both 65W, four-core, eight-thread desktop processors from different eras of silicon design. Benchmark results show a consistent advantage for the AMD part across all tested Cinebench workloads, with the Ryzen 5 PRO 1500 winning all six head-to-head comparisons by margins ranging from 18.3% to 18.6%. Despite the Intel chip’s advanced integrated graphics and newer memory support at its launch, the data indicates that the Zen-based AMD processor delivers superior compute performance in every measured category.

FAQ

Q: Which processor has a higher average benchmark score?

A: The AMD Ryzen 5 PRO 1500 has an average benchmark score of 2246, while the Intel Core i7-5775C scores 2224. This places the AMD part slightly ahead, with its nearest rival being the Intel Core i7-10710U at 2248 (a -0.1% delta), while the Intel chip’s closest competitor is the Intel Core i7-8559U at 2225 (a 0% delta).

Q: How do the two compare in Cinebench R23 multi-core performance?

A: The AMD Ryzen 5 PRO 1500 scores 7766 in Cinebench R23 multi-core, which is 18.6% higher than the Intel Core i7-5775C’s 6549. This is the largest absolute performance gap between the two chips in any benchmark test.

Q: Are both processors unlocked for overclocking?

A: Yes, both the AMD Ryzen 5 PRO 1500 and the Intel Core i7-5775C have their multiplier unlocked. This means both parts allow user-controlled frequency adjustments, though the data does not specify the resulting overclocking headroom for either.

Q: What memory types do these CPUs support?

A: The AMD Ryzen 5 PRO 1500 supports DDR4 memory, while the Intel Core i7-5775C supports DDR3 memory. Both use a dual-channel memory bus, but the Intel chip has a specified memory bandwidth of 25.6 GB/s; no bandwidth figure is provided for the AMD part.

Q: Do these processors include integrated graphics?

A: The Intel Core i7-5775C includes Iris Pro Graphics 6200, whereas the AMD Ryzen 5 PRO 1500 does not have any integrated graphics listed in its specifications. This makes the Intel chip a more self-contained solution for systems without a discrete GPU.

Q: What is the release date difference between the two?

A: The Intel Core i7-5775C was released on 2015-05-14, while the AMD Ryzen 5 PRO 1500 launched on 2017-06-28. The AMD part is therefore roughly two years newer, which aligns with its architectural improvements in the benchmark data.

Where Each One Wins

The AMD Ryzen 5 PRO 1500 wins decisively in all six head-to-head benchmark comparisons. Its largest margins come in the Cinebench R20 multi-core test, where it scores 3261 versus the Intel’s 2750, a 18.6% advantage. The same 18.6% delta appears in Cinebench R23 multi-core (7766 vs 6549) and Cinebench R20 single-core (460 vs 388). The pattern is consistent: AMD leads by 18.3% in Cinebench R15 single-core (110 vs 93) and 18.5% in Cinebench R15 multi-core (782 vs 660).

The Intel Core i7-5775C has no benchmark wins in this dataset. However, its advantage lies outside the Cinebench suite: it is the only one of the two with integrated graphics (Iris Pro Graphics 6200), providing a functional display output and media capabilities without a discrete GPU. The Intel part also lists a specific memory bandwidth of 25.6 GB/s, whereas the AMD chip has no such figure, suggesting the Intel platform may have a more defined memory throughput profile for certain workloads. For users who prioritize raw CPU rendering performance, the AMD part is the clear choice; for those needing an all-in-one CPU with graphics, the Intel chip holds a unique feature.

Architecture Differences

The two processors represent different architectural generations. The AMD Ryzen 5 PRO 1500 uses the Zen microarchitecture, codenamed Summit Ridge, built on a 14 nm process by GlobalFoundries. It packs 4,800 million transistors on a 192 mm² die. In contrast, the Intel Core i7-5775C uses the Broadwell architecture, also on a 14 nm process but fabricated by Intel, with a die size of 182 mm² and no transistor count listed.

Cache configurations diverge significantly. The AMD part has 96 KB of L1 cache per core and 512 KB of L2 per core, with a shared 16 MB L3 cache. The Intel chip offers 64 KB L1 per core and 256 KB L2 per core, with a much smaller 6 MB shared L3 cache. This larger L3 on the AMD side likely contributes to its performance lead in the benchmark results, though no direct causality is established in the data.

Memory support is another architectural split: the Ryzen 5 PRO 1500 uses DDR4, while the Core i7-5775C uses DDR3. The Intel chip also lists PCIe Gen 3 with 16 lanes (CPU only), while the AMD part has no PCIe specification provided. The Intel processor includes integrated Iris Pro Graphics 6200, a feature entirely absent from the AMD chip. Both parts have their multipliers unlocked, but their sockets differ: AMD uses Socket AM4, and Intel uses Socket 1150.

Specification Differences

The two CPUs share several core specifications: both have 4 cores, 8 threads, a 3.70 GHz boost clock, a 65W TDP, dual-channel memory, no ECC support, an unlocked multiplier, and an "Active" production status. Their differences are notable in base clock, socket, memory type, and cache hierarchy.

The AMD Ryzen 5 PRO 1500 runs a base clock of 3.50 GHz, which is 0.20 GHz higher than the Intel’s 3.30 GHz base. The AMD part fits into AMD Socket AM4, while the Intel chip uses Intel Socket 1150. Memory support differs as described: DDR4 for AMD, DDR3 for Intel, with the Intel part having a stated 25.6 GB/s bandwidth. Cache sizes are larger on the AMD side for all three levels: 96 KB vs 64 KB L1 per core, 512 KB vs 256 KB L2 per core, and 16 MB vs 6 MB shared L3.

The Intel Core i7-5775C has an integrated GPU (Iris Pro Graphics 6200) and a PCIe Gen 3, 16-lane interface, while the AMD Ryzen 5 PRO 1500 lists neither. The Intel chip also has a launch MSRP of $366, which is stated once here as historical data; the AMD part has no launch MSRP listed. The AMD processor’s part number is YD150BBBM4GAE, and the Intel’s is SR2AG. Release dates differ by over two years, with Intel launching on 2015-05-14 and AMD on 2017-06-28.

Head-to-Head Benchmarks

The Cinebench test suite shows a uniform performance advantage for the AMD Ryzen 5 PRO 1500 across every workload. In the multi-core tests, the margin is consistently 18.5% to 18.6%. The Cinebench R15 multi-core score of 782 for AMD versus 660 for Intel represents an 18.5% lead. This gap extends to Cinebench R20 multi-core, where AMD scores 3261 against Intel’s 2750, a 18.6% difference. The Cinebench R23 multi-core test shows the same 18.6% delta, with AMD at 7766 and Intel at 6549.

Single-core performance tells a similar story. In Cinebench R15 single-core, the AMD chip scores 110 versus the Intel’s 93, a 18.3% advantage. The Cinebench R20 single-core test shows AMD at 460 and Intel at 388, a 18.6% lead. Cinebench R23 single-core again yields an 18.6% delta, with scores of 1096 for AMD and 924 for Intel. Across all six tests, the AMD Ryzen 5 PRO 1500 wins by a minimum of 18.3% and a maximum of 18.6%, with no test where the Intel Core i7-5775C closes the gap.

The Intel chip’s only additional benchmarks, not present in the head-to-head table, are Geekbench scores of 4989 multi-core and 1441 single-core. These are not compared directly to AMD, but they contribute to its average benchmark score of 2224, which trails the AMD’s 2246. The data suggests that the AMD part’s architectural advantages—larger caches, higher base clock, and newer memory standard—translate into a consistent and substantial performance edge in rendering workloads. The Intel processor’s integrated graphics and specific memory bandwidth remain its distinguishing features, but they do not offset the compute deficit measured here.
