AMD Ryzen 7 PRO 4750U vs Intel Xeon E-2278GEL Comparison

The AMD Ryzen 7 PRO 4750U and Intel Xeon E-2278GEL are both 8-core, 16-thread processors, but they target opposite ends of the computing spectrum: one is a 15-watt mobile part, the other a 35-watt server/workstation chip. Their aggregate benchmark scores are nearly identical — the AMD averages 2965 points versus the Intel’s 2956, a mere 0.3% difference — yet their individual workload results diverge sharply, revealing that raw core counts alone do not define performance. The data shows two distinct performance personalities separated by architecture, power envelope, and market intent.

Head-to-Head Benchmarks

The most striking split occurs in the Cinebench suite, where the two chips trade victories depending on the rendering workload version. In Cinebench R15 multi-core, the Ryzen 7 PRO 4750U posts 1410 points against the Xeon E-2278GEL’s 1030, a decisive 36.9% advantage for AMD. The single-core R15 test reinforces this pattern, with the AMD scoring 181 versus the Intel’s 145, a 24.8% lead. These are not marginal wins; they represent a generational efficiency gap, with the Zen 2 architecture extracting substantially higher throughput per clock in this legacy benchmark.

However, the narrative flips entirely in Cinebench R23, which is more representative of modern rendering workloads. The Xeon E-2278GEL scores 10220 multi-core points, beating the Ryzen’s 8359 by 18.2%. The single-core R23 result follows suit, with Intel’s 1442 outpacing AMD’s 1215 by 15.7%. This reversal is notable: the same two chips, running different versions of the same software, produce opposite winners. The R15 results favor the AMD’s higher boost clock and IPC, while the R23 results suggest the Intel’s larger 16 MB L3 cache and sustained power delivery under longer workloads provide a tangible advantage.

The head-to-head tally is exactly even at two wins each, and the average benchmark scores confirm this parity — the Ryzen’s 2965 is only 0.3% above the Xeon’s 2956. Yet the delta percentages in the individual tests are far larger than the aggregate suggests. This is a classic case where a single average score obscures wild variance: the AMD wins by up to 36.9% in one test, while the Intel wins by up to 18.2% in another. Benchmark results indicate that neither chip is universally faster; the winner depends entirely on the workload’s duration and instruction profile.

Architecture Differences

The architectural gulf between these two processors is substantial. The Ryzen 7 PRO 4750U is built on TSMC’s 7 nm process node, packing 9,800 million transistors into a 156 mm² die. It uses the Zen 2 architecture under the Renoir codename, with a base clock of 1700 MHz and a boost clock of 4.10 GHz. The Xeon E-2278GEL, by contrast, relies on Intel’s 14 nm process, with a larger 180 mm² die and the older Coffee Lake architecture. Its base clock is higher at 2000 MHz, but its boost clock is lower at 3.90 GHz.

Cache configurations differ meaningfully. Both share 64 KB of L1 per core, but the AMD provides 512 KB of L2 per core versus the Intel’s 256 KB per core. The L3 cache is where the tables turn: the AMD has 8 MB shared, while the Intel has 16 MB shared — double the capacity. This larger L3 pool likely explains the Xeon’s stronger Cinebench R23 performance, as longer render tasks benefit from more resident working data. The AMD’s smaller L3 is compensated by its higher per-core L2 and faster boost clock, which favors shorter, bursty workloads.

The process node difference is stark: 7 nm versus 14 nm. This explains the TDP divergence — 15 watts for the AMD versus 35 watts for the Intel — and the performance-per-watt implications. The AMD’s smaller transistors allow it to hit higher boost clocks at a fraction of the power, while the Intel’s larger process node requires more energy to reach similar frequencies. The foundry split (TSMC for AMD, Intel for Intel) and the transistor count (9,800 million for AMD, unreported for Intel) further underscore the manufacturing era gap between a 2020 mobile part and a 2019 server chip.

Where Each One Wins

The Ryzen 7 PRO 4750U wins in scenarios that favor high single-thread burst performance and power efficiency. Its 24.8% lead in Cinebench R15 single-core and 36.9% lead in R15 multi-core indicate that legacy software, or workloads that do not scale with large caches, run substantially faster on the AMD. The 4.10 GHz boost clock, combined with the 7 nm process, makes it a strong choice for lightly threaded tasks like spreadsheet calculations, web browsing, or interactive coding sessions where responsiveness matters more than sustained throughput.

The Xeon E-2278GEL wins in sustained multi-threaded rendering, as evidenced by its 18.2% lead in Cinebench R23 multi-core. The 16 MB L3 cache and 35-watt power budget allow it to maintain higher average clocks over longer durations, which is critical for video encoding, 3D rendering, or compilation jobs that run for minutes rather than seconds. The single-core R23 result, a 15.7% Intel advantage, is also notable — it suggests that the Xeon’s higher base clock (2000 MHz versus 1700 MHz) provides a more stable performance floor under sustained load, even when boost clocks are lower.

The market segments reinforce this split: the AMD is a mobile part (Socket FP6) designed for laptops, while the Intel is a server/workstation part (Socket 1151) built for always-on professional systems. The AMD’s integrated Radeon RX Vega 7 graphics and lack of ECC support point toward consumer productivity, whereas the Intel’s UHD Graphics P630 and ECC memory support indicate mission-critical reliability requirements. For a compact, battery-conscious notebook, the Ryzen’s wins are more relevant; for a rack-mounted render node with continuous power, the Xeon’s sustained throughput takes precedence.

Specification Differences

The two processors differ across nearly every major specification field. The AMD uses Socket FP6, while the Intel uses Socket 1151 — they are not interchangeable. The AMD’s base clock is 1700 MHz versus the Intel’s 2000 MHz, but the AMD’s boost clock is 4.10 GHz versus the Intel’s 3.90 GHz. TDP is a major differentiator: 15 watts for AMD, 35 watts for Intel. Process node is 7 nm (TSMC) for AMD versus 14 nm (Intel) for Intel, with die sizes of 156 mm² and 180 mm² respectively. The AMD has 9,800 million transistors; the Intel does not report a figure.

L2 cache per core is 512 KB on AMD versus 256 KB on Intel, while L3 cache is 8 MB shared on AMD versus 16 MB shared on Intel. Memory support differs: the AMD supports DDR4 and LPDDR4 with 51.2 GB/s bandwidth, whereas the Intel supports only DDR4 at 42.7 GB/s bandwidth. ECC memory is unsupported on AMD but supported on Intel. PCIe lanes are 12 on AMD versus 16 on Intel, both Gen 3. Integrated graphics are Radeon RX Vega 7 on AMD versus UHD Graphics P630 on Intel.

Market segment is mobile for AMD and server/workstation for Intel. The AMD is marked as active in production, while the Intel is end-of-life. Release dates are May 2020 for AMD and June 2019 for Intel. The Intel has a launch MSRP of $519; the AMD has no listed launch MSRP. The AMD’s part number is 100-000000101, and the Intel’s is SRGE2. Neither processor has an unlocked multiplier.
