CPU Comparison

The Intel Xeon E-2224 and the Intel Core i7-980X are both end-of-life processors, yet they represent two very different philosophies in Intel’s lineup. The Xeon E-2224 is a modern, efficient 4-core server part, while the i7-980X is a legacy 6-core desktop extreme edition. Benchmark results show a clear, consistent victory for the newer Xeon, but the underlying architecture tells a more nuanced story about why that is. The data indicates that the Xeon E-2224 wins every single head-to-head benchmark, but the i7-980X retains advantages in raw core count and platform features that matter for specific workloads.

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Xeon E-2224 outperforms the Intel Core i7-980X across every single Cinebench test. In the Cinebench R15 multicore test, the Xeon scores 614 against the i7-980X’s 584, a 5.1% advantage. This pattern holds in single-core performance as well, where the Xeon’s 86 points beat the i7-980X’s 82 by 4.9%. The margins are remarkably consistent, suggesting a fundamental per-core speed advantage rather than a workload-specific quirk.

Moving to Cinebench R20, the Xeon E-2224 again takes the lead, scoring 2559 in multicore versus 2434 for the i7-980X, a 5.1% delta. The single-core result is similar: 361 for the Xeon versus 343 for the i7-980X, a 5.2% gap. These numbers are notable because the i7-980X has 50% more cores and 200% more threads, yet still loses the multicore race. The Xeon’s higher clock speeds and newer architecture compensate for its core deficit.

The largest absolute difference appears in Cinebench R23 multicore, where the Xeon E-2224 scores 6093 against the i7-980X’s 5797. That is a 5.1% lead, consistent with the other tests. In R23 single-core, the Xeon’s 860 points beat the i7-980X’s 818 by 5.1% as well. Across all six head-to-head benchmarks, the Xeon E-2224 wins 6 and loses 0. The i7-980X does have one additional benchmark not shared with the Xeon: Geekbench multicore (3247) and singlecore (659), but those are not part of the direct comparison.

What these scores mean is that the Xeon E-2224’s per-core efficiency is its winning weapon. The i7-980X’s extra cores do not translate into a win because its older Westmere architecture is far less efficient per clock. In practical terms, a 5% lead across the board is small, but it is a decisive sweep. The i7-980X’s average benchmark score of 1746 places it just 0.2% behind its nearest rival, the AMD Ryzen 3 4300U, while the Xeon E-2224’s average of 1762 puts it 0.2% ahead of the Intel Core i5-5675C. Both processors sit at the 41st percentile of all CPUs, meaning they are statistically equivalent in overall performance tiers, yet the Xeon is consistently faster in every direct test.

Architecture Differences

The architectural gap between these two processors is vast, explaining the benchmark results. The Xeon E-2224 is built on Intel’s 14 nm process node, while the i7-980X uses a much older 32 nm process. This node difference alone accounts for significant improvements in power efficiency and clock speed potential. The Xeon’s die size is 126 mm², whereas the i7-980X’s die is 239 mm², despite the i7-980X having more cores. The i7-980X also packs 1,170 million transistors, a figure not provided for the Xeon, but its larger die and older node suggest a less dense design.

Core and thread counts are the most obvious difference: the Xeon E-2224 has 4 cores and 4 threads, while the i7-980X has 6 cores and 12 threads. The i7-980X supports hyper-threading, effectively doubling its thread count, whereas the Xeon does not. However, the Xeon compensates with higher clocks: a 3.40 GHz base and 4.60 GHz boost, versus the i7-980X’s 3.33 GHz base and 3.60 GHz boost. The Xeon’s boost clock is a full 1.0 GHz higher, which is the primary driver of its per-core performance lead.

Cache configurations also differ. Both have 64 KB of L1 and 256 KB of L2 per core, but the Xeon E-2224 has 8 MB of shared L3 cache, while the i7-980X has 12 MB. The i7-980X’s larger L3 cache is a legacy advantage for workloads that fit within it, but the Xeon’s smaller cache is faster due to the newer architecture. Memory support is another split: the Xeon uses DDR4 with dual-channel memory and a bandwidth of 42.7 GB/s, while the i7-980X uses DDR3 with triple-channel memory and no listed bandwidth figure. The Xeon also supports ECC memory, a key server feature, while the i7-980X does not.

Platform connectivity differs as well. The Xeon E-2224 uses Intel Socket 1151 and PCIe Gen 3 with 16 lanes from the CPU, whereas the i7-980X uses Intel Socket 1366 and PCIe Gen 2. The Xeon includes integrated UHD Graphics P630, while the i7-980X has no integrated graphics. The Xeon’s multiplier is locked, but the i7-980X’s is unlocked, allowing for overclocking. The Xeon launched in 2019, the i7-980X in 2010, a nine-year gap that explains the architectural leap from Westmere to Coffee Lake.

FAQ

The Verdict

The data points to a clear verdict: the Intel Xeon E-2224 is the superior processor for most workloads. It wins every benchmark test, offers a higher boost clock, supports modern DDR4 memory with ECC, and includes integrated graphics. Its 14 nm architecture is far more efficient than the i7-980X’s 32 nm design, and its 71 W TDP is significantly lower than the i7-980X’s 130 W. The Xeon’s launch MSRP was $193, and it is aimed at the server/workstation market, where its ECC support and stability features are critical.

The Intel Core i7-980X, however, is not without its merits. It offers 6 cores and 12 threads, a larger 12 MB L3 cache, and an unlocked multiplier for overclocking enthusiasts. Its triple-channel DDR3 memory support is a legacy feature that can provide high bandwidth if the user has the right platform. But in direct benchmark comparisons, these advantages do not translate into wins. The i7-980X’s 41st percentile ranking matches the Xeon’s, but its lower average benchmark score (1746 vs 1762) means it is slightly slower overall.

For a modern buyer, the Xeon E-2224 is the rational choice. It is faster in every tested scenario, uses less power, and supports current memory standards. The i7-980X is a historical curiosity, a product of the 2010 extreme edition era, but its performance is outdated. The only scenario where the i7-980X might be preferable is if an overclocker wants to push its unlocked multiplier to compensate for its lower stock clocks, or if a user has a legacy Socket 1366 platform with triple-channel DDR3 memory and wants a cheap upgrade. But from a pure performance standpoint, the Xeon E-2224 is the winner.

Where Each One Wins

The Intel Xeon E-2224 wins in every benchmark category that both processors share. It is the clear victor in Cinebench R15, R20, and R23, both multicore and single-core. Its wins are consistent, ranging from 4.9% to 5.2%, and they stem from its higher boost clock and modern 14 nm architecture. The Xeon also wins on platform features: it supports DDR4 with ECC, has integrated graphics, and consumes significantly less power (71 W vs 130 W). For server or workstation tasks that prioritize single-threaded performance, reliability, and energy efficiency, the Xeon E-2224 is the only choice. Its 4.60 GHz boost clock is a full 1.0 GHz higher than the i7-980X’s, making it ideal for lightly-threaded workloads like database queries or application serving.

The Intel Core i7-980X wins in areas not covered by the direct benchmarks. It has 6 cores and 12 threads, offering 50% more cores and 200% more threads than the Xeon. For workloads that are heavily multithreaded and can use more than 4 threads, the i7-980X’s raw thread count is a theoretical advantage, but the benchmark data shows it still loses the multicore tests. Its 12 MB L3 cache is 50% larger than the Xeon’s 8 MB, which could benefit certain cache-sensitive applications. The i7-980X also has an unlocked multiplier, allowing overclocking to boost its 3.60 GHz boost clock, and it uses triple-channel DDR3 memory, which could provide higher memory bandwidth if the platform supports it. However, these are speculative advantages that do not appear in the provided benchmark results. The i7-980X’s real strength is as a collectible or for use in a legacy Socket 1366 system, not as a competitive performer.
