Intel Xeon E-2224G vs Intel Xeon E3-1585 v5 Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the Intel Xeon E3-1585 v5 across every benchmark in the comparison. Out of six head-to-head tests, the E3-1585 v5 wins all six, with the E-2224G trailing by roughly 10% in each discipline. This is not a marginal victory; it is a consistent, repeatable gap that appears in both single-threaded and multi-threaded workloads.

Looking at Cinebench R15, the E3-1585 v5 scores 720 in the multi-core test, while the E-2224G manages 644. That is a 10.6% deficit for the newer chip. The single-core R15 result follows the same pattern: 101 for the E3-1585 v5 versus 90 for the E-2224G, a 10.9% gap. These are the largest deltas in the entire comparison, and they set the tone for everything else.

Moving to Cinebench R20, the E3-1585 v5 posts 3001 multi-core and 423 single-core. The E-2224G counters with 2687 and 379 respectively. The deltas here are 10.5% for multi-core and 10.4% for single-core. The pattern holds steady, suggesting that the advantage is structural rather than workload-specific.

Cinebench R23 tells the same story. The E3-1585 v5 reaches 7146 multi-core and 1008 single-core. The E-2224G finishes at 6398 and 903. Both deltas sit at 10.5% and 10.4%, respectively. If anything, the consistency of these numbers across three different Cinebench versions indicates that the performance difference is baked into the architecture and thread configuration, not a quirk of any one test.

It is notably the E-2224G has a higher boost clock. Its recorded boost frequency is 4.70 GHz, while the E3-1585 v5 boosts to only 3.90 GHz. Despite that clock advantage, the E3-1585 v5 still wins every test. That is a telling result: raw clock speed does not overcome the E3-1585 v5's additional threads. The E-2224G is a 4-core, 4-thread part, while the E3-1585 v5 is a 4-core, 8-thread part. In heavily threaded workloads, that doubling of threads matters more than a 0.80 GHz boost advantage.

The average benchmark scores from the database reinforce this. The E-2224G has an average score of 2117, placing it at the 46th percentile of all CPUs. The E3-1585 v5 has an average score of 2067, also at the 46th percentile. These are effectively identical overall standings, which is surprising given the head-to-head results. The explanation lies in the nearest rival data. The E-2224G sits within 0.4% of several chips, including the Intel Atom C5125 at 2122 and the Intel Core i7-1160G7 at 2124. The E3-1585 v5 sits near the AMD Ryzen 5 3400G at 2059 and the Intel Xeon E5-2628 v3 at 2076. Both CPUs occupy a similar performance tier relative to the broader market, but in direct comparison, the E3-1585 v5 is clearly ahead.

Architecture Differences

The two processors come from different architectural generations and target different physical formats. The E-2224G is built on the Coffee Lake architecture, specifically the Coffee Lake-S WS die, using Intel's 14 nm process. It fits into Intel Socket 1151, a mainstream socket that allows for standard motherboard mounting. The E3-1585 v5 is a Skylake part, specifically Skylake-H, also on Intel's 14 nm process, but it uses Intel BGA 1440, meaning it is soldered directly to the board. That is a significant difference for system builders: the E-2224G is replaceable, while the E3-1585 v5 is not.

The die sizes differ substantially. The E-2224G measures 126 mm², while the E3-1585 v5 measures 171 mm². The E3-1585 v5 also has a listed transistor count of 2,300 million, whereas the E-2224G has no recorded transistor count in the database. The larger die and higher transistor count suggest a more complex design, which aligns with its integrated graphics and thread capabilities.

Cache layout is identical in structure: both have 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3. So the cache hierarchy does not explain the performance gap. The difference comes from elsewhere.

Thread count is the obvious architectural split. The E-2224G has 4 threads total, one per core. The E3-1585 v5 has 8 threads, two per core. This is the single biggest functional difference between the two. In the benchmark data, the multi-core tests show the E3-1585 v5 ahead by about 10.5%, which is a modest gain for having twice the threads. The single-core tests also show it ahead by about 10.4%, which is surprising because single-core performance should not benefit from hyper-threading. This suggests the E3-1585 v5's cores are simply more efficient per clock, despite the lower boost frequency.

Memory support differs as well. The E-2224G supports DDR4 only, with a dual-channel bus and a recorded memory bandwidth of 42.7 GB/s. The E3-1585 v5 supports both DDR3 and DDR4, also dual-channel, but its memory bandwidth is recorded at 34.1 GB/s. So the newer chip has a memory bandwidth advantage on paper, yet this does not translate into a performance win.

Integrated graphics are another divergence. The E-2224G carries HD Graphics P630, while the E3-1585 v5 carries Iris Pro Graphics P580. The database records no benchmark scores for either iGPU, so the analysis must remain qualitative: the Iris Pro part is generally positioned as the stronger graphics solution, but the data does not quantify that.

Both are end-of-life products. The E-2224G was released on 2019-05-28, and the E3-1585 v5 on 2016-05-30. Both support ECC memory and use PCIe Gen 3 with 16 lanes from the CPU. Neither has an unlocked multiplier.

The Verdict

From the data alone, the Intel Xeon E3-1585 v5 is the faster processor in every measured test. It wins all six head-to-head benchmarks with deltas ranging from 10.4% to 10.9%. If the sole criterion is raw benchmark performance, the choice is unambiguous: the E3-1585 v5.

However, the E-2224G is not without merit. It has a significantly higher boost clock, 4.70 GHz versus 3.90 GHz, and a higher memory bandwidth rating, 42.7 GB/s versus 34.1 GB/s. It also uses a socketed format, Intel Socket 1151, which makes it a more practical choice for systems that require CPU upgradeability or replacement. The E3-1585 v5 is BGA-mounted, which means it is permanently attached to the board.

The launch MSRP for the E-2224G is $213, and the launch MSRP for the E3-1585 v5 is $556. That is a large difference, but the database does not provide any performance-per-dollar analysis, so this verdict stays strictly on benchmark merits.

For a builder who values raw compute throughput and can accept a fixed, non-upgradeable CPU, the E3-1585 v5 is the better choice. It delivers a consistent 10% advantage across Cinebench R15, R20, and R23, in both single-core and multi-core tests. For a builder who needs a socketed processor with higher boost clocks and faster memory bandwidth, the E-2224G is the more flexible option, though it will lose in direct computation.

The percentile data shows both chips at the 46th percentile of all CPUs, meaning they sit in the same broad performance class. The head-to-head results refine that picture: within that class, the E3-1585 v5 is the stronger performer.

Where Each One Wins

Based strictly on the benchmark data, the E3-1585 v5 wins every measured workload. There is no benchmark category in the database where the E-2224G comes out ahead. The six head-to-head tests span Cinebench R15, R20, and R23, covering both single-core and multi-core scenarios, and the E3-1585 v5 takes all of them with deltas between 10.4% and 10.9%.

The E-2224G does hold advantages in other recorded fields, but those are not benchmark wins. It has a higher boost clock, 4.70 GHz versus 3.90 GHz, which may help in bursty, lightly threaded scenarios that are not captured by the Cinebench suite. It also has a higher memory bandwidth rating, 42.7 GB/s versus 34.1 GB/s, which could matter for memory-sensitive applications that the database does not test. And its socketed format gives it a structural advantage in maintainability and upgradeability, even though that is not a performance metric.

For a system that will run heavily threaded workloads, such as compilation, rendering, or virtualization, the E3-1585 v5 is the pick from the data. For a system where the CPU needs to be replaceable or where higher boost clocks and memory bandwidth are priorities, the E-2224G offers those specific traits, even if the benchmark scores do not favor it. The database records zero benchmark wins for the E-2224G, so any argument for it must rest on the non-benchmark specifications.
