Intel Core i3-13100T vs Intel Xeon E5-1680 v3 Comparison

The Verdict

The data is unambiguous: the Intel Xeon E5-1680 v3 wins every head-to-head benchmark in this comparison, taking all six Cinebench tests with margins between 3.9% and 4.2%. If the database shows a winner, it is the Xeon, despite its 2014 release date and end-of-life production status. The Core i3-13100T, while newer and active in production, does not surpass the Xeon in any recorded Cinebench test.

The Xeon E5-1680 v3 is the pick for workloads that rely on sustained multi-threaded rendering. Its 8 cores and 16 threads outnumber the Core i3's 4 cores and 8 threads, and the benchmark results confirm that advantage: the Xeon leads by 4.1% in Cinebench R23 multi-core (11289 vs 10840) and by 4.2% in Cinebench R20 multi-core (4741 vs 4552). The single-core results are closer, but the Xeon still edges ahead, which contradicts the expectation that a newer, higher-boost part would dominate.

The Core i3-13100T is the choice for a compact, low-power desktop build. Its 35 W TDP versus the Xeon's 140 W TDP is a massive difference, and its integrated UHD Graphics 730 means no separate GPU is required for basic display output. It also supports both DDR4 and DDR5 memory, while the Xeon is limited to DDR4. The Core i3's active production status and modern Socket 1700 platform make it the sensible option for a new system, even if the Xeon holds a slight performance edge in these specific tests.

Do not pick the Xeon for a new build. It is end-of-life, uses a legacy Socket 2011-3, and lacks integrated graphics. Do not pick the Core i3 if maximum multi-threaded Cinebench throughput is the sole criterion; the Xeon wins every time. The data says the Xeon is faster, but the Core i3 is far more practical.

Architecture Differences

The two processors come from different eras and design philosophies. The Intel Xeon E5-1680 v3 is built on the Haswell-EP architecture using a 22 nm process node, with 2,600 million transistors on a 356 mm² die. It is a server and workstation part, designed for quad-channel DDR4 memory and 40 PCIe Gen 3 lanes from the CPU. The Core i3-13100T uses the Raptor Lake architecture on a 10 nm process node, with a 163 mm² die, and targets the desktop market with dual-channel memory support and 20 PCIe Gen 5 lanes.

Core counts differ sharply. The Xeon has 8 cores and 16 threads, while the Core i3 has 4 cores and 8 threads. Cache layouts also diverge: the Xeon provides 64 KB of L1 and 256 KB of L2 per core, plus 20 MB of shared L3 cache. The Core i3 offers 80 KB of L1 and 1.25 MB of L2 per core, but only 12 MB of shared L3. The larger per-core L2 on the Core i3 partially compensates for its lower core count in single-threaded tasks, yet the benchmark data shows the Xeon still wins single-core tests.

Clock speeds tell a different story. The Xeon has a higher base clock at 3.20 GHz versus 2.50 GHz, but the Core i3 boosts higher at 4.20 GHz versus 3.80 GHz. The Core i3 also has a lower TDP of 35 W versus 140 W, reflecting its efficiency-focused design. The Xeon supports ECC memory; the Core i3 does not. The Core i3 includes UHD Graphics 730, while the Xeon has no integrated graphics.

Memory bandwidth is another differentiator. The Xeon's quad-channel memory bus delivers 68.3 GB/s, a figure the database records. The Core i3's dual-channel bus has no recorded bandwidth number in the pack, but the channel count difference is clear. The Xeon's part number is QFSSSR20H, the Core i3's is SRMBT. The Xeon has an unlocked multiplier; the Core i3 is locked. The Xeon was released on September 7, 2014; the Core i3 on January 3, 2023.

Head-to-Head Benchmarks

The Xeon E5-1680 v3 wins all six recorded comparisons. The largest margins appear in Cinebench R20, where the Xeon leads by 4.2% in both multi-core (4741 vs 4552) and single-core (669 vs 642). The R15 tests show a 4.1% multi-core lead (1137 vs 1092) and a 3.9% single-core lead (160 vs 154). The R23 tests show a 4.1% multi-core lead (11289 vs 10840) and a 4.1% single-core lead (1593 vs 1530).

The multi-core results align with the core count advantage. The Xeon has twice as many cores, yet its lead is only around 4%. This suggests that the Core i3's higher boost clock and newer architecture close much of the gap. The Core i3's 4.20 GHz boost is 0.40 GHz higher than the Xeon's 3.80 GHz, and its larger per-core L2 cache likely helps sustain single-thread performance.

The single-core results are notable because they contradict the generation gap. The Xeon's 3.20 GHz base clock is higher, and it wins single-core tests by roughly 4%. The Core i3's superior boost clock does not translate into a win. The database shows the Xeon ahead in R15 single-core (160 vs 154), R20 single-core (669 vs 642), and R23 single-core (1593 vs 1530).

There is one benchmark the Core i3 has that the Xeon does not: Geekbench. The database records Geekbench multi-core at 4993 and single-core at 1780 for the Core i3, but no comparable Geekbench results exist for the Xeon. This means the Core i3 has a broader benchmark portfolio, but within the shared Cinebench suite, the Xeon is undefeated.

The overall average benchmark score favors the Xeon. The Xeon's average is 3265, while the Core i3's is 3198. The Xeon sits at the 53rd percentile among all CPUs, and the Core i3 also sits at the 53rd percentile. The Xeon's nearest rivals include the Xeon E5-1660 v4 at 3264 (0% delta) and the Ryzen Embedded V2516 at 3277 (-0.4%). The Core i3's nearest rivals include the Core i7-9700E at 3197 (0% delta) and the Core i5-1240P at 3202 (-0.1%).

Where Each One Wins

The Xeon E5-1680 v3 wins every recorded Cinebench test, so its use case is clear: any workload measured by Cinebench, including multi-threaded rendering and single-threaded tasks, favors the Xeon. Its 8 cores and 16 threads, combined with 20 MB of shared L3 cache and a 68.3 GB/s memory bandwidth, make it suited for server or workstation environments where ECC memory is required and where the 140 W TDP is acceptable. The unlocked multiplier also allows overclocking, which the Core i3 cannot do.

The Core i3-13100T wins where the Xeon is not competitive: power efficiency and platform modernity. Its 35 W TDP is a fraction of the Xeon's 140 W, making it ideal for low-power or compact desktop systems. Its integrated UHD Graphics 730 removes the need for a discrete GPU in basic builds. Its support for both DDR4 and DDR5 memory gives flexibility in memory choice, and its Gen 5 PCIe lanes, though fewer at 20, offer newer connectivity. The Core i3 is active and on the current Socket 1700 platform, whereas the Xeon is on the legacy Socket 2011-3.

The data does not show any benchmark where the Core i3 wins. The Geekbench scores for the Core i3 (4993 multi-core, 1780 single-core) are recorded, but there are no Geekbench results for the Xeon to compare. Therefore, the only recorded wins belong to the Xeon. The Core i3's advantage is qualitative: lower power, integrated graphics, and newer platform support.
