AMD Ryzen 5 PRO 4650G vs Intel Xeon E-2278GE Comparison

# AMD Ryzen 5 PRO 4650G vs Intel Xeon E-2278GE

The AMD Ryzen 5 PRO 4650G and Intel Xeon E-2278GE are two very different processors aimed at different corners of the market, yet benchmark results show they are remarkably close in raw compute performance. The Ryzen 5 PRO 4650G is a 6-core, 12-thread desktop part from AMD's 4000 series, built on the Zen 2 architecture (Renoir) at TSMC's 7 nm node, while the Xeon E-2278GE is an 8-core, 16-thread server/workstation chip from Intel's E-2200 series, using Coffee Lake-S WS at Intel's 14 nm node. Despite the Xeon's two additional cores and higher boost clock, the data shows the AMD part winning all six head-to-head benchmark comparisons, albeit by a razor-thin margin of 0.5% in every test.

Where Each One Wins

Looking strictly at the benchmark data, the AMD Ryzen 5 PRO 4650G wins every single head-to-head comparison. There are no benchmark categories where the Intel Xeon E-2278GE comes out ahead. The AMD part edges out the Intel chip in both single-core and multi-core tests across Cinebench R15, R20, and R23, with each victory representing a 0.5% delta. This means the Ryzen 5 PRO 4650G holds a consistent, if narrow, performance advantage across all tested workloads.

However, the "win" is more nuanced than a simple sweep suggests. The Xeon E-2278GE has a higher boost clock (4.70 GHz vs 4.20 GHz) and more cores (8 vs 6), yet it still falls behind. This indicates that the AMD chip's architectural efficiency—likely stemming from its 7 nm process node versus Intel's 14 nm—more than compensates for the core-count deficit in these specific benchmarks. The data shows the Ryzen 5 PRO 4650G winning in Cinebench R15 multicore with a score of 1379 against 1372, in R20 multicore at 5747 versus 5719, and in R23 multicore at 13685 versus 13619. Single-core results follow the same pattern: 194 vs 193 in R15, 811 vs 807 in R20, and 1932 vs 1922 in R23.

For users prioritizing raw multi-threaded throughput in rendering or CPU-bound productivity, the AMD part technically wins, but the margin is so small that it is practically negligible. The Xeon E-2278GE, however, carries the advantage of being a server/workstation part with support for ECC memory, which both CPUs actually support, and it targets a different ecosystem with Intel Socket 1151. The real differentiator is not benchmark performance but platform positioning, which we will explore next.

Architecture Differences

The architectural gap between these two processors is substantial and explains why the benchmark results are so close despite different core counts. The AMD Ryzen 5 PRO 4650G uses the Zen 2 architecture, codenamed Renoir, manufactured on a 7 nm process at TSMC. It packs 9,800 million transistors into a 156 mm² die. In contrast, the Intel Xeon E-2278GE uses the older Coffee Lake architecture (Coffee Lake-S WS), built on Intel's 14 nm process with a 180 mm² die size; no transistor count is listed in the data.

Cache configuration differs significantly. Both have 64 KB of L1 per core, but the AMD chip has 512 KB of L2 per core versus 256 KB per core on the Intel. More importantly, the Xeon E-2278GE has 16 MB of shared L3 cache, double the 8 MB shared L3 found on the Ryzen 5 PRO 4650G. This larger L3 cache on the Intel part may help it close the performance gap in certain workloads, even though it cannot overcome the AMD chip's efficiency advantage in these tests.

Clock speeds also tell a story. The AMD part has a higher base clock of 3.70 GHz versus 3.30 GHz on the Intel, but the Xeon has a higher boost clock of 4.70 GHz versus 4.20 GHz. The Xeon's higher boost clock likely explains why it gets so close in single-core benchmarks, while the AMD's higher base clock and superior IPC per clock help it maintain the lead. The TDP difference is notable: the AMD part draws 65 W versus 80 W for the Intel chip, meaning the Ryzen 5 PRO 4650G delivers its performance with lower power consumption.

Memory bandwidth also favors AMD: 51.2 GB/s versus 42.7 GB/s, though both use dual-channel DDR4. Both support ECC memory. The integrated graphics differ as well—AMD uses Radeon Vega 7, while Intel uses UHD Graphics P630. The AMD chip is a desktop part on Socket AM4, while the Intel is a server/workstation part on Socket 1151. The Xeon E-2278GE is end-of-life, while the Ryzen 5 PRO 4650G remains active in production.

Head-to-Head Benchmarks

The head-to-head results are remarkably consistent, with AMD winning every test by exactly 0.5%. Starting with Cinebench R15 multicore, the Ryzen 5 PRO 4650G scores 1379 against 1372 for the Xeon E-2278GE. In single-core R15, the margin is 194 versus 193. Moving to Cinebench R20, multicore results show 5747 for AMD and 5719 for Intel, while single-core shows 811 versus 807. In the more demanding Cinebench R23, the multicore scores are 13685 for AMD and 13619 for Intel, with single-core at 1932 versus 1922.

These results are striking because the Xeon E-2278GE has two more cores and a higher boost clock. A 0.5% margin across all tests suggests the AMD chip's architectural advantages—7 nm process, higher base clock, more L2 cache per core, and higher memory bandwidth—fully offset the Intel part's core-count and L3 cache advantages. The data shows no test where the Intel chip wins, and the delta is identical in every case, indicating a consistent per-watt or per-clock efficiency edge for the AMD part.

The Geekbench results are only available for the AMD chip, not for the Intel part. The Ryzen 5 PRO 4650G scores 6629 in Geekbench multicore and 1440 in single-core. This absence of a comparative Geekbench score for the Xeon E-2278GE means the head-to-head analysis is limited to Cinebench tests, but those six comparisons all favor AMD. The average benchmark score for the AMD part is 3977, while the Intel part sits at 3939, a gap of about 1% overall, consistent with the individual test margins.

The Verdict

The benchmark data presents a clear, if narrow, winner: the AMD Ryzen 5 PRO 4650G outperforms the Intel Xeon E-2278GE in every tested workload. With six wins out of six head-to-head comparisons, all by 0.5%, the AMD part demonstrates that its 6-core, 12-thread configuration on the 7 nm Zen 2 architecture is more efficient than Intel's 8-core, 16-thread Coffee Lake design on 14 nm. The AMD chip achieves this with a lower TDP of 65 W versus 80 W, higher memory bandwidth of 51.2 GB/s versus 42.7 GB/s, and a higher base clock of 3.70 GHz versus 3.30 GHz.

For users prioritizing raw benchmark scores in Cinebench workloads, the Ryzen 5 PRO 4650G is the data-supported choice. It wins in both single-core and multi-core tests, and it does so with lower power consumption and a more modern process node. The Intel Xeon E-2278GE, however, offers double the L3 cache (16 MB vs 8 MB) and a higher boost clock (4.70 GHz vs 4.20 GHz), which could matter in workloads not represented in these benchmarks. The Xeon also carries a launch MSRP of $519, though the data does not provide a comparable price for the AMD part.

From a platform perspective, the choice depends on ecosystem needs. The AMD part is a desktop processor on Socket AM4, while the Intel part is a server/workstation chip on Socket 1151. The Xeon E-2278GE is end-of-life, whereas the Ryzen 5 PRO 4650G remains active. Given that the AMD chip wins all benchmarks, has a lower TDP, and is still in production, the data favors it for users who value performance efficiency. The Intel part's only advantages are its larger L3 cache and higher boost clock, but those do not translate into wins in any of the tested Cinebench scenarios. For a neutral analysis based strictly on the available data, the AMD Ryzen 5 PRO 4650G is the better performer in this matchup.
