Intel Xeon E-2278G vs Intel Xeon E-2278GE Comparison

The Intel Xeon E-2278G and Intel Xeon E-2278GE are two of the closest-matched chips in the entire database. Both are eight-core, sixteen-thread Coffee Lake workstation processors built on Intel's 14 nm node, both carry the same 16 MB of shared L3 cache, and both occupy Socket 1151. On paper they differ only in clock speeds, thermal envelope, and integrated graphics branding. The recorded benchmark data, however, tells a quietly consistent story: the lower-clocked, lower-TDP E-2278GE wins every single head-to-head test, by margins ranging from 0.5 to 0.9 percent. This page breaks down where each chip wins, how their architectures align and diverge, and what the numbers mean in context. Neither part remains in production, both having reached end-of-life status, but they remain reference points for entry workstation builds of their era.

Where Each One Wins

Strictly by the head-to-head results, the E-2278GE wins everywhere. It sweeps all six recorded Cinebench contests: R15 multi-core, R15 single-core, R20 multi-core, R20 single-core, R23 multi-core, and R23 single-core. The E-2278G records zero wins across the shared test suite. The E-2278G's launch MSRP was $494, while the E-2278GE launched at $519.

That said, the split deserves interpretation rather than a simple verdict. The margins are small enough that neither chip offers a performance argument over the other; a sub-one-percent gap in any direction is within the range of run-to-run variation for rendering tests of this kind. The real use-case split is thermal and platform oriented. The E-2278GE carries an 80 W TDP, fifteen watts below the E-2278G's 95 W, which makes it the more natural fit for compact or thermally constrained workstations despite its nominally lower clocks. The E-2278G, with a higher 5.00 GHz boost ceiling versus 4.70 GHz, is positioned for enclosures where the extra thermal headroom can be spent chasing peak single-thread frequencies.

There is also a niche distinction in benchmark coverage. The database holds Geekbench results for the E-2278G, a multi-core score of 7354 and a single-core score of 1633, but no Geekbench entries for the E-2278GE. That is a data-coverage gap rather than a performance gap, but buyers cross-shopping using Geekbench as a filter will find recorded evidence only for the E-2278G.

Architecture Differences

In architectural terms these are the same silicon. Both chips belong to the Xeon E-2200 series, use the Coffee Lake architecture with the Coffee Lake-S WS codename, are fabbed by Intel on a 14 nm process, and measure 180 mm² per die. Both pack eight cores and sixteen threads with symmetric cache hierarchies: 64 KB of L1 per core, 256 KB of L2 per core, and 16 MB of shared L3. Neither has an unlocked multiplier, and both target the Server/Workstation segment over Socket 1151.

The differences sit at the margins, and they are meaningful ones. The E-2278G runs a 3.40 GHz base clock and a 5.00 GHz boost clock inside a 95 W TDP. The E-2278GE runs a slightly lower 3.30 GHz base and a notably lower 4.70 GHz boost, but does so within an 80 W TDP. In other words, the E-2278GE trades top-end frequency for efficiency, a profile typical of chips destined for dense or low-airflow chassis. The launch dates are close, with the E-2278G releasing on 2019-05-28 and the E-2278GE following on 2019-06-10.

Integrated graphics differ only in branding: the E-2278G ships with HD Graphics P630 while the E-2278GE lists UHD Graphics P630. Everything else on the platform side is identical: DDR4 memory support, a dual-channel memory bus, 42.7 GB/s of memory bandwidth, ECC memory support, and PCIe Gen 3 with 16 CPU lanes. Part numbers distinguish the chips as SRFB2 for the E-2278G and SRGDY for the E-2278GE.

Head-to-Head Benchmarks

The E-2278GE's sweep is comprehensive but tight. In Cinebench R15 multi-core, the E-2278GE scores 1372 against the E-2278G's 1360, a 0.9 percent edge. Single-core R15 goes the same way, 193 to 192, a 0.5 percent margin. Cinebench R20 repeats the pattern: 5719 to 5670 in multi-core and 807 to 800 in single-core, both 0.9 percent wins for the GE. The newest test in the shared set, Cinebench R23, shows 13619 versus 13502 in multi-core and 1922 versus 1906 in single-core, margins of 0.9 and 0.8 percent respectively.

The striking part is that the E-2278GE posts these wins despite a boost clock 0.30 GHz lower than its sibling's. The data suggests that, in sustained rendering workloads, the GE's tighter thermal envelope either allows more consistent all-core behavior or simply lands within measurement noise of the higher-TDP part. Either reading leads to the same conclusion: paying for the higher boost ceiling of the E-2278G buys no measurable rendering advantage in the recorded results.

Against the wider field, both chips sit at the 57th percentile of all CPUs in the database, squarely mid-pack. The E-2278G carries an average benchmark score of 4052, and its nearest rivals frame that number tightly. The AMD Ryzen Threadripper 1900X averages 4073, a 0.5 percent delta; the Intel Core i5-12500TE averages 4083, 0.8 percent ahead; the Intel Core i5-12400T averages 4019, 0.8 percent behind; and the AMD Ryzen 5 PRO 4655G averages 4010, a 1 percent gap. The E-2278GE's average score of 3939 draws an equally close rival set: the AMD Ryzen 9 5900HS at 3924 (0.4 percent behind), the AMD Ryzen 3 7330U at 3958 (0.5 percent ahead), the Intel Xeon E5-2669 v3 at 3959 (0.5 percent ahead), and the Intel Core i7-6900K at 3970 (0.8 percent ahead). In short, both processors trade blows at parity with a mixed field of desktop and mobile parts, and the 113-point spread between the two siblings is smaller than the gaps separating either from its own nearest rivals.

FAQ

Q: Which chip is faster in the recorded benchmarks?

A: The E-2278GE, by a narrow margin. It wins all six head-to-head Cinebench tests, with deltas between 0.5 and 0.9 percent in its favor.

Q: Does the E-2278G's higher boost clock translate into better performance?

A: No. Its 5.00 GHz boost versus the GE's 4.70 GHz does not produce a win in any recorded test. The database shows the lower-boost part ahead across the entire shared suite.

Q: Which one runs cooler or fits tighter systems?

A: The E-2278GE, on paper. Its TDP is 80 W versus 95 W for the E-2278G, making it the better candidate for thermally constrained workstations.

Q: Do they use the same socket and platform features?

A: Yes. Both use Intel Socket 1151, support DDR4 ECC memory over a dual-channel bus with 42.7 GB/s of bandwidth, and provide PCIe Gen 3 with 16 CPU lanes.

Q: How do they compare against other CPUs in the database?

A: Both sit at the 57th percentile versus all CPUs. The E-2278G averages 4052 and trades within roughly 1 percent of rivals like the AMD Ryzen Threadripper 1900X and Intel Core i5-12500TE, while the E-2278GE averages 3939 and sits within 0.8 percent of chips like the Intel Xeon E5-2669 v3 and Intel Core i7-6900K.

Q: Are these chips still in production?

A: No. Both are marked end-of-life. The E-2278G launched on 2019-05-28 and the E-2278GE on 2019-06-10.

Specification Differences

The two chips differ in only a handful of fields. Base clock: 3.40 GHz on the E-2278G versus 3.30 GHz on the E-2278GE. Boost clock: 5.00 GHz versus 4.70 GHz. TDP: 95 W versus 80 W. Integrated graphics branding: HD Graphics P630 versus UHD Graphics P630. Part number: SRFB2 versus SRGDY. Release date: 2019-05-28 versus 2019-06-10. Average benchmark score: 4052 versus 3939, with the GE holding the edge in every individual head-to-head test despite the lower aggregate, which reflects the GE's smaller recorded test coverage rather than inferior results. Everything else, from core count and cache to memory support and PCIe configuration, is identical between the two.
