Intel Core i7-13790F vs Intel Xeon 636 Comparison

The Verdict

The Intel Core i7-13790F and Intel Xeon 636 serve different masters. The database shows the Xeon 636 winning 9 of the 17 head-to-head benchmarks, while the Core i7-13790F takes 8. That near-even split masks a clear thematic divide: the Xeon dominates rendering workloads, while the Core i7 wins most everyday and integer-heavy tasks.

Pick the Xeon 636 if your priority is Cinebench throughput or extended instruction workloads. It leads by 6.2% in every Cinebench multicore test and by 6.2% to 6.3% in single-core Cinebench runs. It also crushes the Core i7 in extended instructions by 19.5% and in find prime numbers by 18.8%. The Xeon is the stronger choice for physics simulation too, scoring 3645 against 3017, a 17.2% gap.

Pick the Core i7-13790F if you need encryption speed, integer math, or rapid string sorting. It wins data encryption by 16.6%, integer math by 9.5%, and random string sorting by 7.7%. Its single-thread Passmark score of 4212 beats the Xeon's 3937 by 7%. The Core i7 also edges out the Xeon in floating point math by 2.5% and multithread by 0.7%.

The average benchmark score tells the same story. The Core i7 sits at 63080, the Xeon at 61360. Both CPUs land in the 92nd and 93rd percentiles respectively, meaning they are near the top of the database, but the Core i7 holds a slight overall edge. The Xeon's nearest rivals are all Core i9 parts (13900T, 13900K, 13900KF), with deltas between 0.6% and 0.8%. The Core i7's nearest rivals include Core Ultra 7 and Ryzen AI parts, all within 0.5% either way.

For a desktop builder, the Core i7 is the pragmatic pick: it is a 65 W desktop part with DDR4 and DDR5 support. For a workstation builder, the Xeon's quad-channel memory, ECC support, and 80 PCIe Gen 5 lanes make it the infrastructure play. The data does not crown a single winner; it splits the crown by workload.

Architecture Differences

The two chips come from different Intel lineages. The Core i7-13790F uses Raptor Lake-S, built on Intel's 10 nm process with a 257 mm² die. The Xeon 636 uses Granite Rapids, built on a 5 nm process with a 598 mm² die. The Xeon's die is more than twice the size, reflecting its server-oriented design.

Core counts differ substantially. The Core i7 packs 16 cores and 24 threads, while the Xeon has 12 cores and 24 threads. Both support the same thread count, but the Core i7 gets there with more physical cores. The Xeon compensates with much higher clocks at base: 3.50 GHz versus 2.10 GHz. At boost, the Core i7 pulls ahead at 5.20 GHz versus 4.70 GHz.

Cache layouts diverge. The Core i7 has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Xeon has 112 KB of L1 per core, 2 MB of L2 per core, and 48 MB of shared L3. The Xeon's larger L1 and L3 give it a memory hierarchy advantage, particularly for workloads that reuse data.

Memory support splits cleanly. The Core i7 supports both DDR4 and DDR5 over a dual-channel bus and has no ECC. The Xeon supports only DDR5 over a quad-channel bus with ECC enabled, and the database records its memory bandwidth at 204.8 GB/s. PCIe connectivity also differs: the Core i7 offers Gen 5 with 20 CPU lanes, while the Xeon offers Gen 5 with 80 CPU lanes.

The Xeon is socketed for Intel Socket 4710, the Core i7 for Intel Socket 1700. The Xeon has an unlocked multiplier, the Core i7 does not. The Xeon has no integrated graphics, while the Core i7's integrated graphics field is null in the database. The Xeon carries a 170 W TDP versus the Core i7's 65 W.

Release timing differs by years. The Core i7 launched on 2023-02-09, the Xeon on 2026-02-01. The Xeon's launch MSRP is $639, the Core i7's is $441.

Head-to-Head Benchmarks

The Xeon 636 dominates the Cinebench suite without exception. In R15 multicore it scores 3805 against 3568, a 6.2% lead. R20 multicore sees 15857 versus 14869, again 6.2%. R23 multicore shows 37757 versus 35404, 6.2%. The single-core tests follow the same pattern: R15 at 537 versus 503, R20 at 2238 versus 2099, R23 at 5330 versus 4998. Every Cinebench delta sits between 6.2% and 6.3%, indicating a consistent clock-for-clock advantage in rendering.

The Xeon also wins the extended instructions test decisively. Its score of 43282 dwarfs the Core i7's 34828, a 19.5% gap. That is the largest single delta in the entire comparison. Find prime numbers goes to the Xeon as well, 255 versus 207, an 18.8% lead. Passmark physics follows with 3645 versus 3017, a 17.2% win.

The Core i7-13790F fights back in Passmark's compute and data tests. Data encryption is its best result: 31703 versus 27193, a 16.6% advantage. Integer math shows 151416 versus 138281, a 9.5% win. Random string sorting lands at 58607 versus 54420, a 7.7% edge. Single-thread Passmark gives the Core i7 4212 versus 3937, a 7% win. Floating point math is closer, 110512 versus 107826, just 2.5% apart.

The multithread Passmark test is the tightest contest. The Core i7 scores 44737, the Xeon 44421, a 0.7% margin. Data compression also favors the Core i7, 567473 versus 550395, a 3.1% lead. These narrow wins show that in raw parallel throughput the two chips are nearly interchangeable, despite their architectural differences.

Where Each One Wins

The Xeon 636 wins all rendering tests. If a workload is built around Cinebench, extended SIMD instructions, prime number computation, or physics simulation, the Xeon is the clear choice. Its 6.2% Cinebench sweep and 19.5% extended instructions lead make it the stronger compute engine for professional rendering and scientific workloads. The 17.2% physics win reinforces that pattern.

The Core i7-13790F wins encryption, integer math, floating point math, string sorting, and single-thread Passmark. That makes it the better pick for general desktop use, database-style integer operations, compression, and any workload that depends on single-thread responsiveness. Its 16.6% encryption lead is particularly relevant for security-sensitive applications.

The multithread Passmark result, with the Core i7 ahead by 0.7%, suggests that for mixed parallel workloads the difference is negligible. The Xeon's 12 cores at higher base clocks trade blows with the Core i7's 16 cores and higher boost clock. The Xeon's quad-channel memory and 204.8 GB/s bandwidth give it a memory throughput edge that shows in bandwidth-hungry server tasks. The Core i7's 65 W TDP and dual-channel flexibility make it the lower-power desktop option.

The database's percentile figures place both in the top tier: 93rd for the Core i7, 92nd for the Xeon. Neither chip is a slouch. Choose the Xeon for rendering, instructions, and server duty. Choose the Core i7 for encryption, integer work, and a balanced desktop experience.
