Intel Core 5 320 vs Intel Core Ultra 9 285T Comparison

The Verdict

The recorded data delivers a clear verdict: the Intel Core Ultra 9 285T dominates the Intel Core 5 320 across every benchmark in the database. The Ultra 9 wins all 17 head-to-head tests, with no wins recorded for the Core 5 320. The average benchmark score for the Ultra 9 285T is 51310, placing it in the 91st percentile of all CPUs, while the Core 5 320 averages 18023, sitting in the 72nd percentile. The Ultra 9 is the choice for any workload requiring heavy processing, from multi-core rendering to data encryption. The Core 5 320, with its 6 cores and 6 threads, targets a different segment entirely: mobile devices with modest power envelopes. The data shows the Ultra 9 285T is 185% higher in average benchmark score, a gap that no single-core advantage can close.

The Core 5 320 does hold one meaningful edge: its launch MSRP of $340 versus the Ultra 9 285T's launch MSRP of $549. But the performance delta is so lopsided that the price gap does little to change the verdict. The Ultra 9 285T delivers roughly 2.8 times the average benchmark score, and its single-thread PassMark score of 4576 exceeds the Core 5 320's 4045 by 13.1%. For desktop users with room for a 35 W processor, the Ultra 9 285T is the only rational pick from this data. For ultra-portable mobile designs where the 15 W Core 5 320 fits, the choice is dictated by the platform, not by performance.

Architecture Differences

The two processors come from different Intel families with distinct designs. The Core 5 320 belongs to the Wildcat Lake generation, built on a 3 nm process at Intel's own foundry. The Ultra 9 285T is part of the Core Ultra Series 2, codenamed Arrow Lake-S, also on a 3 nm node but fabricated by TSMC. The Ultra 9 285T includes a transistor count of 17,800 million and a die size of 243 mm², figures not recorded for the Core 5 320.

Core and thread counts differ sharply. The Core 5 320 provides 6 cores and 6 threads with no hyperthreading, while the Ultra 9 285T offers 24 cores and 24 threads. The cache hierarchy reinforces this gap. The Core 5 320 has 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The Ultra 9 285T lists 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The Ultra 9's L3 alone is six times larger than the Core 5's entire shared pool.

Memory architecture also diverges. The Core 5 320 supports DDR5 and LPDDR5X over a single-channel bus, delivering 59.7 GB/s of bandwidth. The Ultra 9 285T supports DDR5 over a dual-channel bus at 102.4 GB/s. The Ultra 9 also enables ECC memory, a feature absent on the Core 5 320. PCIe connectivity differs as well: the Core 5 320 offers Gen 4 with 6 CPU lanes, while the Ultra 9 285T provides Gen 5 with 20 CPU lanes. Integrated graphics are present on both: Intel Xe3 Graphics with 2 Xe cores on the Core 5 320, and Arc Xe-LPG Graphics with 64 EU on the Ultra 9 285T.

Sockets and market segments cement the platform split. The Core 5 320 uses Intel BGA 1516, a soldered mobile socket, while the Ultra 9 285T uses Intel Socket 1851 for desktop builds. The Core 5 320 is classified as a mobile part; the Ultra 9 285T is a desktop part. Release dates also differ: the Core 5 320 launched later, on 2026-04-15, while the Ultra 9 285T appeared on 2025-01-06. Both CPUs are currently marked as Active in production, and neither has an unlocked multiplier.

Head-to-Head Benchmarks

The Ultra 9 285T wins every recorded head-to-head benchmark. The margins vary by workload, and the data reveals where the gap is narrowest and widest.

The smallest lead appears in PassMark single-thread tests. The Ultra 9 285T scores 4576 against the Core 5 320's 4045, a delta of -11.6%. This shows that while the Ultra 9 still wins in single-core performance, the Core 5 320 is comparatively closer in lightly threaded work. The Core 5's 4.60 GHz boost clock helps it stay within reach, though the Ultra 9's 5.40 GHz boost takes the lead.

Multi-core tests show a far larger divide. In Cinebench R23 multi-core, the Ultra 9 285T scores 33573 versus 6197, a delta of -81.5%. This is the largest gap in the entire benchmark set. The Core 5 320's 6 cores simply cannot match the Ultra 9's 24 cores in heavily parallel workloads. Cinebench R20 multi-core shows a similar pattern: 14100 for the Ultra 9 against 5462 for the Core 5, a -61.3% delta. Cinebench R15 multi-core follows with 3384 versus 1054, a -68.9% delta.

Cinebench single-core results also favor the Ultra 9 substantially. In Cinebench R23 single-core, the Ultra 9 scores 4739 versus 1926, a -59.4% delta. Cinebench R20 single-core shows 1990 versus 771, a -61.3% delta. Cinebench R15 single-core has 477 versus 276, a -42.1% delta. The single-core advantage is not as extreme as multi-core, but it is still decisive.

PassMark workloads reinforce the same conclusion. In data compression, the Ultra 9 scores 384140 against 148779, a -61.3% delta. Data encryption shows 32061 versus 10984, a -65.7% delta. Extended instructions yield 27477 versus 13262, a -51.7% delta. Find prime numbers scores 345 versus 110, a -68.1% delta. Floating point math produces 137923 versus 42440, a -69.2% delta. Integer math shows 132433 versus 32323, a -75.6% delta. PassMark multithread scores 39931 versus 15450, a -61.3% delta. Physics tests give 2842 versus 1221, a -57% delta. Random string sorting has 47695 versus 18038, a -62.2% delta.

The nearest rival data puts both processors in context. The Core 5 320 sits within 0.7% of the AMD Ryzen 5 1600, the Intel Core 5 120U, the Intel Core i5-1334U, and the AMD Ryzen 5 3600XT in average score. The Ultra 9 285T sits within 1.2% of the Intel Core i9-14900T, the Intel Core i9-13900F, the Intel Core i7-13850HX, and the AMD Ryzen 9 5900XT. The Core 5 320's nearest rivals are older or lower-tier parts, while the Ultra 9 285T competes with flagship-class desktop processors.

Where Each One Wins

The Intel Core Ultra 9 285T wins in every measured category. No benchmark in the database records a win for the Intel Core 5 320. The Ultra 9's advantages are most pronounced in multi-threaded and throughput-oriented workloads. Cinebench R23 multi-core, integer math, and data compression show the largest margins, driven by the 24-core configuration and the 36 MB shared L3 cache. The Ultra 9 also leads in single-thread tests, though by a smaller margin, thanks to its 5.40 GHz boost clock.

The Core 5 320 is not without a role, but its strengths lie outside the benchmark scores. Its 15 W TDP makes it suitable for mobile platforms with limited cooling and battery budgets. Its single-channel memory bus and 6 MB L3 cache are modest, but the processor is built for a different physical form factor: Intel BGA 1516 is a soldered mobile socket, not a desktop platform. The Core 5 320 also supports LPDDR5X memory, which is not listed for the Ultra 9 285T, and its integrated Intel Xe3 Graphics with 2 Xe cores may serve basic display tasks in compact systems.

The Ultra 9 285T, by contrast, is a desktop part with a 35 W TDP, dual-channel memory at 102.4 GB/s, PCIe Gen 5 with 20 lanes, and ECC support. Its 24 cores and 24 threads place it in the 91st percentile of all CPUs. For workloads such as rendering, encryption, compression, and physics simulation, the recorded data shows no scenario where the Core 5 320 closes the gap. The use-case split is therefore clear: the Ultra 9 285T for desktop compute, the Core 5 320 for low-power mobile designs where the 15 W envelope and BGA socket are the deciding factors.
