Intel Core 5 320 vs Intel Core Ultra 5 245T Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the Intel Core Ultra 5 245T across all 17 head-to-head benchmark comparisons. The Intel Core 5 320 does not register a single win in any tested workload, which makes this comparison unusually one-sided. The largest margin appears in Cinebench R23 multicore, where the Ultra 5 245T scores 26208 against 6197 for the Core 5 320, a delta of -76.4%. That is the widest gap in the entire dataset, and it reflects a fundamental difference in thread capacity and sustained performance.

The single-core results tell a more moderate story. In PassMark single-thread, the Ultra 5 245T posts 4367 versus 4045, a delta of -7.4%. That is the narrowest margin recorded between the two parts. Cinebench R15 single-core shows a -25.8% gap, with the Ultra 5 245T at 372 and the Core 5 320 at 276. The Ultra 5 245T also leads in Cinebench R20 single-core by -50.4%, scoring 1553 against 771. These figures indicate that while the Ultra 5 245T has a clear single-thread advantage, its multicore dominance is far more pronounced.

In floating-point math, the Ultra 5 245T scores 108499 against 42440, a -60.9% delta. Integer math shows a -63.5% gap, 88676 versus 32323. Prime number finding is even more lopsided at -66%, with scores of 324 and 110. Data compression favors the Ultra 5 245T at 283812 versus 148779, a -47.6% delta. Data encryption shows a -53.6% gap, 23656 against 10984. Extended instruction workloads produce a -39.9% delta, with 22071 versus 13262. The physics test gives the Ultra 5 245T a -46.4% advantage, 2278 against 1221. Random string sorting is -48.4%, 34931 versus 18038. The multi-thread PassMark score is -49.9%, 30833 against 15450.

The average benchmark score reflects this dominance: the Ultra 5 245T sits at 38194, while the Core 5 320 sits at 18023. The Ultra 5 245T also holds an 86th percentile among all CPUs, versus 72nd for the Core 5 320.

Architecture Differences

The two processors come from different design families. The Intel Core 5 320 uses the Wildcat Lake codename and belongs to the Core 5 generation. The Intel Core Ultra 5 245T uses the Arrow Lake-S codename, belongs to the Core Ultra Series 2, and is built on the Arrow Lake architecture. Both use a 3 nm process node, but the Core 5 320 is fabricated by Intel while the Ultra 5 245T is fabricated by TSMC.

The core and thread counts differ substantially. The Core 5 320 has 6 cores and 6 threads, meaning no hyperthreading. The Ultra 5 245T has 14 cores and 14 threads, also without extra threads per core. This 8-core gap explains much of the multicore performance difference. The Core 5 320 has a base clock of 1.50 GHz and a boost clock of 4.60 GHz. The Ultra 5 245T has a base clock of 2.20 GHz and a boost clock of 5.10 GHz. The higher clocks on the Ultra 5 245T contribute to its single-thread wins.

Cache hierarchies are also different. The Core 5 320 has 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The Ultra 5 245T has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The larger L3 on the Ultra 5 245T, 24 MB versus 6 MB, is a major factor in workloads that benefit from larger working sets. The transistor count and die size are only recorded for the Ultra 5 245T: 17,800 million transistors on a 243 mm² die. No equivalent data exists for the Core 5 320.

Memory support differs as well. The Core 5 320 supports DDR5 and LPDDR5X with a single-channel bus and 59.7 GB/s of bandwidth. The Ultra 5 245T supports DDR5 with a dual-channel bus and 102.4 GB/s of bandwidth. ECC memory is supported on the Ultra 5 245T but not on the Core 5 320. PCIe connectivity favors the Ultra 5 245T, which offers Gen 5 with 20 lanes from the CPU, while the Core 5 320 offers Gen 4 with 6 lanes from the CPU.

Integrated graphics also differ. The Core 5 320 uses Intel Xe3 Graphics with 2 Xe cores. The Ultra 5 245T uses Arc Xe-LPG Graphics with 64 execution units. The market segments are different: the Core 5 320 is a mobile part on Intel BGA 1516, while the Ultra 5 245T is a desktop part on Intel Socket 1851. The Core 5 320 has a TDP of 15 watts, while the Ultra 5 245T has a TDP of 65 watts. Neither processor has an unlocked multiplier. The Core 5 320 carries part number SAE3H, and the Ultra 5 245T carries part number SRVFF.

Where Each One Wins

The data does not show a single workload category where the Core 5 320 comes out ahead. Every recorded benchmark, from Cinebench R15 to PassMark single-thread, favors the Ultra 5 245T. The closest contest is single-thread performance, where the Ultra 5 245T leads by only -7.4% in PassMark. That suggests the Core 5 320 has competitive per-core capability in lightly threaded tasks, but it is still behind.

The Ultra 5 245T wins decisively in all multicore and throughput-oriented tests. Cinebench R23 multicore shows a -76.4% gap, which is the largest margin in the dataset. Prime number finding, integer math, and floating-point math all show gaps above -60%. These results point to workloads that scale with core count, cache size, and memory bandwidth, all of which favor the Ultra 5 245T.

For the Core 5 320, its mobile design with a 15 watt TDP and single-channel memory makes it suitable for low-power environments where sustained multicore throughput is not the primary requirement. Its single-thread scores, while lower, are closer to the Ultra 5 245T than its multicore scores, indicating that it handles lightly threaded tasks with reasonable efficiency relative to its power envelope. The Ultra 5 245T, with its 65 watt TDP, dual-channel memory, and 14 cores, is positioned for desktop workloads that demand high throughput across many threads.

The Verdict

The benchmark data is unambiguous. The Intel Core Ultra 5 245T outperforms the Intel Core 5 320 in every recorded test, with margins ranging from -7.4% in single-thread PassMark to -76.4% in Cinebench R23 multicore. The Ultra 5 245T has more cores, higher clocks, more cache, dual-channel memory, and a wider PCIe interface. It also supports ECC memory and carries a higher percentile ranking at 86 versus 72.

The Core 5 320 is a 15 watt mobile processor with 6 cores, a 1.50 GHz base clock, and a 4.60 GHz boost clock. Its single-thread performance is within -7.4% of the Ultra 5 245T in PassMark, which is the closest result in the dataset. But it falls far behind in every multicore test, and its nearest rivals are older parts like the AMD Ryzen 5 1600 and the Intel Core i5-1334U.

The launch MSRP for the Core 5 320 is $340, and the launch MSRP for the Ultra 5 245T is $270. The data confirms that the Ultra 5 245T delivers higher performance in every measured category, making it the stronger choice for any workload captured in the database.
