Intel Core Ultra 5 245KF vs Intel Xeon Gold 5320H Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear and consistent picture: the Intel Core Ultra 5 245KF dominates the Intel Xeon Gold 5320H in 14 of the 17 recorded head-to-head tests. The most striking margin comes in PassMark data encryption, where the Core Ultra 5 245KF scores 33,381 against 11,462, a staggering 191.2% advantage. This is the single largest delta in the entire comparison, indicating a fundamental difference in how each processor handles cryptographic workloads.

Cinebench results reinforce this pattern. Across all four Cinebench tests (R15, R20, R23, both multi-core and single-core variants), the Core Ultra 5 245KF holds a nearly uniform lead of 35.9% to 36%. For example, in Cinebench R23 multi-core, the Core Ultra 5 245KF scores 36,647, while the Xeon Gold 5320H trails at 26,960. In single-core R23, the gap is similarly wide: 5,173 versus 3,806, again a 35.9% advantage.

Single-thread performance is another area of total dominance. The PassMark single-thread test shows the Core Ultra 5 245KF scoring 4,715, a 94.2% improvement over the Xeon's 2,428. This is a near-doubling of raw single-core capability, a decisive factor for any workload that cannot fully utilize multiple threads.

The Xeon Gold 5320H does fight back in three specific areas. Its best showing is in PassMark integer math, where it scores 119,955 versus 98,854, a win of 17.6%. It also wins in data compression (500,828 versus 460,123, an 8.1% lead) and random string sorting (62,730 versus 55,206, a 12% lead). These are all throughput-oriented tasks that benefit from the Xeon's higher core count and memory bandwidth.

Other benchmark results follow the Core Ultra's trend. PassMark floating point math shows a 78.1% advantage for the Core Ultra 5 245KF (131,546 vs 73,873). PassMark find prime numbers sees a 166.7% win for the Core Ultra (416 vs 156). PassMark extended instructions yields a 3.7% edge for the Core Ultra (37,912 vs 36,564), and PassMark physics shows a 25.2% lead (2,998 vs 2,395). The Core Ultra also takes the PassMark multithread test, scoring 43,110 versus 31,718, a 35.9% margin.

Architecture Differences

The two processors come from entirely different design philosophies. The Core Ultra 5 245KF is built on Arrow Lake-S, a 3nm process from TSMC, while the Xeon Gold 5320H uses Cooper Lake-SP on Intel's 14nm node. This process gap is the core reason for the dramatic differences in single-thread and power efficiency, as it allows the Core Ultra to clock much higher.

The Core Ultra 5 245KF has 14 cores and 14 threads, with a base clock of 4.20 GHz and a boost clock of 5.20 GHz. It has a 125W TDP and uses the Intel Socket 1851. Its cache hierarchy is notably deep: 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. It supports DDR5 memory over a dual-channel bus, yielding 102.4 GB/s of bandwidth. It has 20 PCIe Gen 5 lanes and no integrated graphics. It is an unlocked part, meaning the multiplier can be adjusted for overclocking.

The Xeon Gold 5320H is a server/workstation processor with 20 cores and 40 threads, a base clock of 2.40 GHz and a boost of 4.20 GHz. It has a 150W TDP and a Socket 4189. Its cache layout is different: 64 KB L1 per core, 1 MB L2 per core, and 27.5 MB shared L3. It supports DDR4 memory over a six-channel bus, providing 128.0 GB/s of bandwidth, a higher total than the Core Ultra. It supports ECC memory, a critical feature for server workloads. It has 48 PCIe Gen 3 lanes and is locked (no multiplier unlocking). The Xeon was released on 2021-04-05, while the Core Ultra was released on 2024-10-23.

The transistor count and die size are only listed for the Core Ultra 5 245KF, which has 17,800 million transistors on a 243 mm² die. The Xeon's figures are not recorded in the database.

The Verdict

The data shows the Intel Core Ultra 5 245KF is the better processor for the vast majority of tasks in this comparison. Every Cinebench test, every PassMark single-threaded test, and the majority of PassMark multi-threaded tests are won by the Core Ultra. The average benchmark score for the Core Ultra is 55,093, versus 52,431 for the Xeon Gold 5320H, a 5.1% overall advantage.

The Core Ultra is the clear choice for anyone prioritizing single-core performance, encryption, floating-point math, prime number finding, or general multi-core throughput across Cinebench and PassMark multithread. Its 94.2% lead in single-thread performance makes it the better desktop and workstation part for typical applications, and its 35.9% lead in Cinebench multi-core shows it can also handle heavily threaded rendering workloads better than the Xeon.

The Xeon Gold 5320H is the winner in three specific PassMark workloads: integer math, data compression, and random string sorting. It also offers ECC memory support, which the Core Ultra does not. Its higher core count (20 vs 14) and thread count (40 vs 14) do not translate into overall superiority in the recorded tests, but they contribute to its wins in those specific integer and string manipulation workloads.

For most users, the Core Ultra 5 245KF is the superior product. For a server or workstation environment where ECC, maximum memory bandwidth, and those specific integer-sorting tasks are paramount, the Xeon Gold 5320H retains a niche. The database records the Core Ultra as having a 91st percentile rank among all CPUs, the same percentile as the Xeon, but its average score is higher.

Where Each One Wins

The Intel Core Ultra 5 245KF is the definitive winner in all single-core performance tests. Cinebench R23 single-core shows a 35.9% lead (5,173 vs 3,806), and PassMark single-thread shows a 94.2% lead (4,715 vs 2,428). This makes it the ideal choice for any application that depends on fast single-threaded execution, such as older games, certain professional software, and interactive workloads.

The Core Ultra also wins every multi-core Cinebench test by the same 35.9% margin, showing that its 14 cores are more efficient than the Xeon's 20 cores in rendering workloads. Its 191.2% win in data encryption and 78.1% win in floating-point math make it the clear choice for scientific computing and security-related tasks.

The Xeon Gold 5320H wins only where raw core count and memory bandwidth can be exploited for specific operations. Its 20 cores and 40 threads give it a 17.6% advantage in integer math (119,955 vs 98,854), an 8.1% advantage in data compression (500,828 vs 460,123), and a 12% advantage in random string sorting (62,730 vs 55,206). Its six-channel memory bus, which provides 128.0 GB/s of bandwidth, is likely a major factor in these workloads.

The Xeon's wins are narrow in percentage terms aside from integer math, and they are concentrated in data manipulation and compression. The Core Ultra's wins are more numerous and often much larger, especially in encryption and single-thread performance. For any workload involving encryption, floating-point math, or general application responsiveness, the Core Ultra 5 245KF is the better hardware. For a server that processes large amounts of integer data and uses compression algorithms, the Xeon Gold 5320H is the better fit.

The data also shows that the Core Ultra is a more modern part, with a 3nm process versus 14nm, and it achieves its wins with a lower TDP (125W vs 150W). The Xeon's 48 PCIe Gen 3 lanes outnumber the Core Ultra's 20 Gen 5 lanes, which might matter for specific expansion scenarios, but the Core Ultra's Gen 5 interface offers higher per-lane bandwidth.
