Intel Core i5-9500T vs Intel Xeon E5-4620 v3 Comparison

Where Each One Wins

The recorded benchmark data is unusually one-sided. Across all six head-to-head tests, the Intel Xeon E5-4620 v3 wins every single comparison. The Core i5-9500T does not claim a single victory in any Cinebench iteration, whether multi-core or single-core. That does not mean the i5-9500T is without merit, but its strengths lie outside raw compute scores.

The Xeon E5-4620 v3 wins by a consistent margin of roughly 7.6% to 7.9% depending on the specific workload. In Cinebench R15 multi-core, it scores 901 against 832 for the i5-9500T, a 7.7% advantage. Single-core in the same test shows 127 versus 117, again a 7.9% edge. The pattern holds in R20 and R23: the Xeon leads by 7.6% in multi-core and 7.7% in single-core. These are not situational wins; the Xeon simply outruns the i5 across every measured scenario.

For workload selection, the Xeon E5-4620 v3 is the choice for anything that scales with thread count. Its 10 cores and 20 threads give it a structural advantage in heavily parallel tasks. The i5-9500T, with 6 cores and 6 threads, cannot match that throughput. Even in single-threaded tests, where its newer Coffee Lake architecture would normally help, the i5 still trails. That is notable because single-core performance is often the one area where a newer, lower-power desktop chip can close the gap with an older server part. Here it does not.

The i5-9500T does win in practical platform terms. It integrates UHD Graphics 630, so it can run a display without a discrete GPU. The Xeon E5-4620 v3 has no integrated graphics at all. For a basic office machine or a home server that needs only occasional display output, the i5 avoids the cost and complexity of a separate graphics card. The Xeon demands one, period.

Power and thermals also favor the i5 in a way the benchmark scores do not capture. The i5-9500T carries a 35 W TDP, while the Xeon E5-4620 v3 sits at 105 W. The database shows that the Xeon uses three times the power budget to deliver a single-digit performance lead. For multi-core rendering jobs that run for hours, that power gap matters. The i5 will draw less, generate less heat, and require a less aggressive cooling solution. The Xeon will need a proper workstation or server chassis with adequate airflow.

The Xeon also wins on memory bandwidth and capacity pathways. It supports quad-channel DDR4 with a recorded 59.7 GB/s of bandwidth, compared to the i5's dual-channel 42.7 GB/s. For database work, large in-memory analytics, or virtual machine hosts, that extra bandwidth is meaningful. The i5's lower bandwidth is fine for typical desktop tasks but will bottleneck in memory-heavy server workloads.

Architecture Differences

The two processors come from different Intel design eras and target different market segments. The i5-9500T is Coffee Lake, built on a 14 nm process, released in 2018. The Xeon E5-4620 v3 is Haswell-EP, built on 22 nm, released in 2015. The i5 is a desktop part; the Xeon is explicitly a server and workstation part.

Core and thread counts differ sharply. The i5 has 6 cores and 6 threads, meaning no Hyper-Threading. The Xeon has 10 cores and 20 threads, with full Hyper-Threading enabled. That is a 4-core and 14-thread difference in the Xeon's favor. The i5's base clock is 2.20 GHz with a boost of 3.70 GHz. The Xeon's base clock is listed as 2000.00 MHz, which is 2.00 GHz, and its boost is 2.60 GHz. The i5 has higher clock speeds, but the Xeon compensates with more cores and threads.

Cache hierarchies diverge after the per-core L1 and L2. Both use 64 KB of L1 per core and 256 KB of L2 per core. The shared L3 is where they separate: the i5 has 9 MB shared, while the Xeon has 25 MB shared. That larger pool of last-level cache helps the Xeon keep more working data on-die, which matters in server workloads with large datasets.

Memory support differs in channel count and bandwidth. The i5 uses dual-channel DDR4 with 42.7 GB/s. The Xeon uses quad-channel DDR4 with 59.7 GB/s. The Xeon also supports ECC memory; the i5 does not. For reliability-critical deployments, ECC is a deciding factor.

PCIe lanes are another major split. The i5 provides 16 PCIe Gen 3 lanes from the CPU. The Xeon provides 40 Gen 3 lanes. That difference dictates expansion capability: the Xeon can host more NVMe drives, more GPUs, or more network cards without a switch chip. The i5 is limited to a typical desktop expansion layout.

The Xeon has a much larger physical die. The database records 2,600 million transistors and a 356 mm² die size for the Xeon. The i5's transistor count and die size are not recorded. The Xeon's larger die reflects its ten cores and massive 25 MB L3 cache. Process technology favors the i5 at 14 nm versus 22 nm, which explains how the i5 achieves higher clocks at much lower power.

The i5 includes UHD Graphics 630 integrated graphics; the Xeon has none. The i5 uses Socket 1151, the Xeon uses Socket 2011-3. Both are end-of-life in production status. The i5's launch MSRP was $192; the Xeon's launch MSRP was $1668. Neither chip is multiplier unlocked.

The Verdict

Pick the Intel Xeon E5-4620 v3 if your work is thread-hungry and you already have or are willing to build a platform around Socket 2011-3. The data shows it wins every benchmark comparison in the head-to-head set. It offers 10 cores and 20 threads, 25 MB of shared L3, quad-channel memory with ECC support, 40 PCIe Gen 3 lanes, and 59.7 GB/s of memory bandwidth. It is the stronger compute engine, full stop. The 7.6% to 7.9% lead in Cinebench tests is consistent across every measured workload. If you are rendering, compiling, running VMs, or processing large datasets, the Xeon's extra cores, threads, cache, and memory bandwidth will be used.

Pick the Intel Core i5-9500T if your priority is low power, integrated graphics, and a standard desktop platform. Its 35 W TDP is a fraction of the Xeon's 105 W. It includes UHD Graphics 630, so no discrete GPU is required for basic display output. It runs on Socket 1151 with dual-channel DDR4, which means cheaper motherboards and standard desktop memory. Its 6 cores and 6 threads are enough for everyday productivity, light content creation, and home server duties that do not demand massive parallelism. Its 3.70 GHz boost clock is significantly higher than the Xeon's 2.60 GHz, which helps in lightly threaded tasks despite the benchmark results showing the Xeon still leads.

Do not pick the i5-9500T expecting it to beat the Xeon in raw rendering performance. The recorded data says it will not. Do not pick the Xeon expecting it to run quietly on a small power supply or without a GPU. It will not do that either. The Xeon wins on performance, the i5 wins on efficiency and platform simplicity.

Head-to-Head Benchmarks

The head-to-head benchmark set contains six tests, all from the Cinebench suite, and the Xeon E5-4620 v3 wins all six. The margin is remarkably consistent, fluctuating only between 7.6% and 7.9% across different workloads and Cinebench versions.

In Cinebench R15 multi-core, the Xeon scores 901 against the i5's 832, a 7.7% difference. In R15 single-core, the Xeon scores 127 against 117, a 7.9% edge. These are the smallest absolute scores in the set, but the percentage gap is similar to the larger tests.

Cinebench R20 shows the same pattern. Multi-core: Xeon 3757, i5 3470, a 7.6% lead for the Xeon. Single-core: Xeon 530, i5 489, a 7.7% lead. The i5's single-core score of 489 is respectable for a 35 W chip, but the Xeon's 530 is simply higher.

Cinebench R23 repeats it. Multi-core: Xeon 8946, i5 8264, a 7.6% advantage. Single-core: Xeon 1263, i5 1166, a 7.7% advantage. The near-constant delta across all six tests suggests a fundamental throughput advantage rather than a workload-specific quirk.

The i5's best single-core result relative to the Xeon is in R23 single-core, where it trails by 7.7%. Its best multi-core result is in R20 and R23, where it trails by 7.6%. There is no test where the i5 comes within 7% of the Xeon, and there is no test where the Xeon extends its lead beyond 7.9%.

For context, the database places the i5-9500T at a 49th percentile among all CPUs, with an average benchmark score of 2493. The Xeon E5-4620 v3 also sits at the 49th percentile, with an average score of 2587. Their nearest rivals reflect this: the i5-9500T is within 0.7% of the Core i3-12100TE and within 0.5% of the Xeon E5-2630 v3, while the Xeon E5-4620 v3 is effectively tied with the Xeon E-2174G and within 0.7% of the Core i7-8850H. The average score difference between the two chips is 94 points, roughly 3.6% in the Xeon's favor, but the Cinebench-specific head-to-head tests show a larger gap of about 7.7%.

The takeaway from the raw numbers is clear: the Xeon E5-4620 v3 outruns the Core i5-9500T in every rendering workload the database recorded. The i5's higher boost clock and newer architecture do not overcome the Xeon's two extra cores, fourteen extra threads, and larger cache.
