CPU Comparison

The Intel Xeon E3-1220 v5 and Intel Core i3-9100TE are both four-core, four-thread processors on the Intel Socket 1151 platform, but they target different eras and priorities. The Xeon is a Skylake-era server/workstation part with a 3.00 GHz base and 3.50 GHz boost clock, while the i3 is a Coffee Lake desktop chip with a 2.20 GHz base and 3.20 GHz boost. The benchmark data shows a clear performance hierarchy, with the older Xeon consistently outrunning the newer i3 across every Cinebench iteration, despite the i3's newer architecture and lower power envelope.

Head-to-Head Benchmarks

The Xeon E3-1220 v5 dominates the head-to-head comparison, winning all six recorded benchmarks with no contests. The margin is remarkably uniform across different workload types. In Cinebench R15, the Xeon scores 488 in multi-core against the i3-9100TE's 393, a 24.2% advantage. The single-core test tells the same story: 68 for the Xeon versus 55 for the i3, also a 23.6% delta. This consistency suggests the Xeon's higher clock speeds are the primary driver, not any architectural advantage in specific instruction paths.

Moving to Cinebench R20, the pattern holds exactly. The Xeon posts 2034 multi-core and 287 single-core, while the i3 manages 1638 and 231 respectively. Both deltas are 24.2%. This is a substantial gap for chips with identical core and thread counts. The i3's newer Coffee Lake architecture does not compensate for its lower operating frequencies. The Xeon's 3.50 GHz boost clock versus the i3's 3.20 GHz boost is the likely culprit, though the Xeon also carries a larger 8 MB shared L3 cache versus the i3's 6 MB.

The newest benchmark, Cinebench R23, shows the largest single-core delta. The Xeon scores 684 single-core, beating the i3's 550 by 24.4%. Multi-core R23 sees the Xeon at 4845 against 3900, a 24.2% lead. The i3-9100TE does have one benchmark in its arsenal that the Xeon lacks, a Geekbench result, but the fact pack provides no Geekbench score for the Xeon, so no comparison is possible there. For every directly comparable metric, the Xeon wins by roughly a quarter.

The average benchmark scores tell a similar story, though the gap narrows. The Xeon's average is 1401, while the i3 sits at 1386, a difference of about 1.1%. This suggests that other benchmarks outside the Cinebench suite might favor the i3, or that the i3's additional Geekbench scores (3214 multi-core, 1105 single-core) pull its average up relative to its Cinebench performance. Still, for pure rendering workloads, the Xeon is the clear winner.

The Verdict

The data points to the Intel Xeon E3-1220 v5 as the superior performer in every head-to-head test. If your workload is heavily dependent on Cinebench-style rendering, which typically scales with raw clock speed and cache size, the Xeon is the pick. Its 24.2% lead across R15, R20, and R23 multi-core tests is decisive. The Xeon also carries ECC memory support, a feature often required in server or workstation environments, and it supports both DDR3 and DDR4 memory types.

However, the i3-9100TE is not without its merits. Its 35 W TDP versus the Xeon's 80 W TDP makes it a far more power-efficient choice for compact or thermally constrained systems. The i3 also includes integrated UHD Graphics 630, which the Xeon lacks entirely, meaning the i3 can power a display without a discrete GPU. The i3's memory bandwidth is also higher at 38.4 GB/s versus the Xeon's 34.1 GB/s, and it only supports DDR4, which is the more modern standard. For a basic desktop or a low-power embedded role, the i3 is the more sensible option despite its performance deficit.

Architecture Differences

The two processors come from different Intel architecture generations. The Xeon E3-1220 v5 is built on the Skylake architecture, specifically the Skylake-DT codename, while the i3-9100TE uses Coffee Lake, part of the Coffee Lake Refresh generation. Both are fabricated on Intel's 14 nm process node, but the Xeon's die is slightly smaller at 122 mm² compared to the i3's 126 mm². The Xeon die contains 1,750 million transistors; the fact pack does not list a transistor count for the i3.

Cache configurations differ notably. Both have 64 KB of L1 and 256 KB of L2 per core, but the shared L3 cache is 8 MB on the Xeon and 6 MB on the i3. This 2 MB difference could contribute to the Xeon's performance edge in cache-sensitive workloads. Memory support also diverges: the Xeon supports both DDR3 and DDR4, while the i3 is DDR4-only. Both use dual-channel memory buses, but the i3 has a higher peak memory bandwidth at 38.4 GB/s versus 34.1 GB/s.

The most significant feature gap is integrated graphics. The i3-9100TE includes Intel UHD Graphics 630, while the Xeon E3-1220 v5 has no integrated GPU listed. This makes the i3 a self-contained solution for basic systems, whereas the Xeon requires a discrete graphics card. Both processors support ECC memory, which is unusual for a desktop i3 but standard for a Xeon. PCIe support is identical: Gen 3 with 16 lanes from the CPU. The Xeon is classified for the server/workstation market segment, while the i3 is a desktop part. Both are end-of-life products, and neither has an unlocked multiplier.

FAQ

Q: Which processor is faster in multi-core Cinebench tests?

A: The Intel Xeon E3-1220 v5 wins all multi-core tests. In Cinebench R23, it scores 4845 versus the i3-9100TE's 3900, a 24.2% advantage. The same margin applies to R15 (488 vs 393) and R20 (2034 vs 1638).

Q: Does the i3-9100TE have any performance advantage over the Xeon?

A: Based on the head-to-head data, no. The Xeon wins all six comparable benchmarks. The i3 does have Geekbench scores (3214 multi-core, 1105 single-core) that are not available for the Xeon, but no direct comparison is possible from the supplied data.

Q: What are the power consumption differences?

A: The i3-9100TE has a 35 W TDP, while the Xeon E3-1220 v5 has an 80 W TDP. The i3 consumes less than half the power of the Xeon, making it more suitable for low-power or thermally limited systems.

Q: Do both processors support ECC memory?

A: Yes, both the Xeon E3-1220 v5 and the i3-9100TE support ECC memory. The Xeon supports both DDR3 and DDR4, while the i3 supports only DDR4.

Q: Which processor has integrated graphics?

A: Only the Intel Core i3-9100TE has integrated graphics, specifically UHD Graphics 630. The Xeon E3-1220 v5 has no integrated GPU listed, so it requires a discrete graphics card for display output.

Q: How do these processors compare to their nearest rivals?

A: The Xeon E3-1220 v5 has an average benchmark score of 1401, nearly identical to the Intel Xeon E-2104G at 1402 (0% delta) and the Intel Core i5-6500TE at 1399 (0.1% delta). The i3-9100TE averages 1386, close to the AMD Opteron 6274 at 1387 (-0.1% delta) and the AMD Opteron 6238 at 1383 (0.3% delta). Both chips sit in the 37th percentile of all CPUs.

Where Each One Wins

The Intel Xeon E3-1220 v5 wins in every directly comparable benchmark scenario. Its 24.2% lead across all Cinebench multi-core tests makes it the clear choice for CPU-bound rendering, video encoding, or any workload that scales with core clock and cache. The larger 8 MB L3 cache and higher 3.50 GHz boost clock give it a structural advantage. The Xeon's ECC memory support and DDR3/DDR4 flexibility also make it more suitable for legacy server environments or workstation builds where data integrity is critical. Its 80 W TDP is higher, but that is the price of performance.

The Intel Core i3-9100TE wins where power efficiency and system simplicity matter more than raw throughput. Its 35 W TDP allows for passive cooling or small-form-factor builds that would struggle with the Xeon's 80 W heat output. The integrated UHD Graphics 630 means a complete system can be built without a discrete GPU, reducing cost and complexity for basic office tasks, media playback, or lightweight embedded applications. The i3's higher memory bandwidth of 38.4 GB/s and native DDR4 support also make it a more modern fit for current motherboards. For a fanless industrial PC or a low-power home server that does not demand maximum rendering performance, the i3-9100TE is the superior choice despite losing every head-to-head benchmark.
