AMD Ryzen 7 2800H vs Intel Core i7-5775R Comparison

Head-to-Head Benchmarks

The recorded data is unusually one-sided. Across six Cinebench comparisons, the AMD Ryzen 7 2800H wins every single test. There is no benchmark in the head-to-head set where the Intel Core i7-5775R takes the lead. The margins are consistent, hovering in a narrow band between 8.7% and 9.0%. That consistency suggests a systematic advantage rather than workload-specific quirks.

In the Cinebench R15 multi-core test, the Ryzen 7 2800H scores 697 against 641 for the Core i7-5775R, a delta of 8.7%. The single-core R15 result is similar: 98 versus 90, an 8.9% advantage. Moving to Cinebench R20, the AMD part scores 2907 multi-core and 410 single-core, while Intel manages 2671 and 376 respectively. Those deltas are 8.8% and 9.0%. In Cinebench R23, the pattern holds: 6922 versus 6360 multi-core (8.8%) and 977 versus 897 single-core (8.9%).

The fact that the single-core margins are just as large as the multi-core margins is notable. The Ryzen 7 2800H has a 0.10 GHz higher base clock (3.40 GHz versus 3.30 GHz) and an identical boost clock of 3.80 GHz. Yet the single-core lead is roughly 9% across all three Cinebench generations. Clock speed alone does not explain the full gap, since the boost clocks are equal. The architecture differences, covered later, must be doing the heavy lifting.

For context, the Ryzen 7 2800H sits at the 45th percentile of all CPUs in the database, with an average benchmark score of 2002. Its nearest rivals in the database include the Intel Core i5-8400T at 2001 (0% delta), the Intel Core i5-8400H at 2003 (-0.1%), and the Intel Xeon D-1712TR at 2004 (-0.1%). The Core i7-5775R also lands at the 45th percentile, with an average score of 2031. Its nearest rivals are the Intel Xeon E3-1240 v5 at 2030 (0%), the Intel Xeon E3-1280 v5 at 2029 (0.1%), and the Intel Xeon E-2124G at 2034 (-0.1%. Despite the Ryzen chip winning the head-to-head tests, the aggregate average scores in the database are close, differing by only 29 points. That suggests the Cinebench suite is a favorable test for the AMD part, while other workloads in the database may close the gap.

Where Each One Wins

The AMD Ryzen 7 2800H wins all six recorded Cinebench comparisons. This covers three generations of the Cinebench renderer, both single-core and multi-core modes. For content creation workloads that scale with Cinebench scores, the data points clearly toward the AMD processor. The multi-core wins of 8.7% to 8.8% mean that heavily threaded rendering tasks, such as 3D scene exports or video encoding that uses all eight threads, should complete faster on the Ryzen 7 2800H.

The single-core wins matter for a different reason. Applications that rely on one or two threads, such as legacy software, spreadsheet recalculations, or older game engines, will see the same 8.9% to 9.0% advantage. The Ryzen 7 2800H does not sacrifice single-thread performance to achieve its multi-thread lead, which is a meaningful distinction. Many processors that win multi-core tests do so by adding cores or clocking high under load, but the AMD part wins both sides of the test suite.

The Intel Core i7-5775R has no wins in the head-to-head benchmark set. However, the database includes an additional Geekbench result for the Intel part that is not present for the AMD part. The Core i7-5775R scores 3996 multi-core and 1218 single-core on Geekbench. Without a corresponding Geekbench score for the Ryzen 7 2800H, the database cannot directly compare those numbers. What the data does show is that the Intel chip has a wider set of recorded measurements, including Geekbench, which may matter for users who put weight on that specific benchmark.

The Intel part also has a higher average benchmark score in the database at 2031 versus 2002 for the AMD part. That is a 1.4% difference in the Intel chip's favor across all recorded benchmarks, even though it loses every head-to-head Cinebench test. This implies that the Geekbench scores, or other unlisted results folded into the average, are more favorable to the Core i7-5775R. Users targeting Geekbench-heavy workloads might see a different picture than the Cinebench head-to-head suggests.

Architecture Differences

The two processors come from different design philosophies and different market segments. The AMD Ryzen 7 2800H is a mobile part built on the Zen architecture, codename Raven Ridge, using a 14 nm process from GlobalFoundries. It uses AMD Socket FP5 and has a 15 W TDP. The Intel Core i7-5775R is a desktop part built on the Broadwell architecture, also on a 14 nm process but fabricated by Intel. It uses Intel BGA 1364 and has a 65 W TDP. The TDP gap is substantial: 15 W versus 65 W. The AMD chip achieves its performance lead while drawing far less power, according to the specification data.

Both processors have 4 cores and 8 threads. The base clocks are close, 3.40 GHz for AMD and 3.30 GHz for Intel, and the boost clocks are identical at 3.80 GHz. The cache layouts differ significantly. The Ryzen 7 2800H has 128 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3. The Core i7-5775R has 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3. The AMD part has double the per-core L1 and L2, while the Intel part has 50% more shared L3.

The die sizes also differ. The AMD chip measures 246 mm², while the Intel chip measures 182 mm². Intel packs its design into a smaller die, which is consistent with its higher TDP and desktop orientation. The memory support diverges as well. The Ryzen 7 2800H uses DDR4 in a dual-channel configuration, while the Core i7-5775R uses DDR3, also dual-channel. The Intel part has a recorded memory bandwidth figure of 29.9 GB/s, while the AMD part has no bandwidth figure in the database. Neither processor supports ECC memory, and neither has an unlocked multiplier.

The integrated graphics differ. The AMD chip carries Radeon RX Vega 11, while the Intel chip carries Iris Pro Graphics 6200. The production statuses are telling: the Ryzen 7 2800H is listed as Active, while the Core i7-5775R is End-of-life. The release dates are also far apart: the AMD chip launched in May 2018, and the Intel chip launched in May 2015. The Intel part is a three-year older design, which may help explain why the newer AMD architecture wins the Cinebench tests despite the Intel part having a 65 W power budget. The Intel part also carries a PCIe Gen 3 specification with 16 lanes (CPU only), while the AMD part has no PCIe data recorded.

The Verdict

The data makes one thing clear: in the Cinebench rendering workloads recorded in the database, the AMD Ryzen 7 2800H is the faster processor. It wins every single head-to-head test by a margin between 8.7% and 9.0%. For users whose primary workloads are Cinebench-style rendering, whether single-threaded or multi-threaded, the AMD part is the better choice. The fact that it does this with a 15 W TDP, versus 65 W for the Intel part, makes the result even more lopsided from an efficiency standpoint.

The Intel Core i7-5775R is not without merits in the database. Its average benchmark score of 2031 is higher than the AMD chip's 2002, and it has Geekbench scores recorded that the AMD chip lacks. Users who weight Geekbench heavily, or who need the Iris Pro Graphics 6200's specific feature set, may find the Intel part more suitable. The Intel chip also has more L3 cache (6 MB versus 4 MB), which could benefit certain cache-sensitive workloads not represented in the head-to-head Cinebench results.

However, the production status tells a practical story. The Ryzen 7 2800H is Active, while the Core i7-5775R is End-of-life. The Intel chip launched in May 2015 and is a Broadwell desktop part with a 65 W TDP and DDR3 memory support. The AMD chip launched in May 2018, uses DDR4, and targets mobile systems. For anyone building or buying a system today, the AMD part is the one with ongoing availability and a modern memory standard.

The verdict from the recorded data is straightforward. Pick the AMD Ryzen 7 2800H for Cinebench-oriented rendering workloads, for lower power consumption, and for an active production part. Consider the Intel Core i7-5775R only if the higher aggregate average score in the database, the Geekbench results, or the larger L3 cache are decisive factors for a specific application. The head-to-head benchmark set favors AMD in every recorded test, and that is the most direct comparison available.
