Intel Core Ultra 5 236V vs Intel Core Ultra 9 285 Comparison

Head-to-Head Benchmarks

The benchmark data records a complete sweep for the Intel Core Ultra 9 285 across all 17 head-to-head comparisons, with zero wins recorded for the Intel Core Ultra 5 236V. The most lopsided margin appears in PassMark integer math, where the Ultra 9 285 scores 164,869 against 38,765 for the Ultra 5 236V, a delta of 76.5% in favor of the larger chip. Floating point math shows a similar pattern, with the Ultra 9 285 delivering 194,988 points versus 52,774, a 72.9% advantage.

Cinebench results confirm the same hierarchy. In Cinebench R23 multicore, the Ultra 9 285 produces 48,945 points compared to 15,628 for the Ultra 5 236V, a 68.1% gap. The single-core R23 test tells a slightly different story, as the Ultra 9 285 still leads but by a smaller relative margin: 6,909 versus 2,206, again a 68.1% delta per the recorded data. The single-thread PassMark score narrows further, with the Ultra 9 285 at 4,881 and the Ultra 5 236V at 3,893, a 20.2% difference. This pattern indicates that the two processors are architecturally similar per core, but the Ultra 9 285 scales far better with additional cores and higher clocks.

Data compression and encryption workloads show the largest absolute gaps. The Ultra 9 285 scores 602,121 in PassMark data compression versus 176,554 for the Ultra 5 236V, a 70.7% delta. Data encryption follows at 46,949 versus 13,049, a 72.2% gap. Extended instructions, a workload that benefits from wide SIMD execution, shows a 65.9% delta (45,357 versus 15,451). The smallest measured difference outside single-thread tests appears in PassMark physics, where the Ultra 9 285 leads 3,598 to 1,503, a 58.2% margin.

Prime number finding, a test sensitive to integer throughput and memory latency, gives the Ultra 9 285 a 459 to 171 advantage, a 62.7% delta. Random string sorting shows a 70.6% gap (73,651 versus 21,628). Every recorded benchmark, from compression to floating point, follows the same direction: the Ultra 9 285 wins, often by margins exceeding 60 percentage points.

Architecture Differences

The two processors belong to the same Core Ultra Series 2 family but target different platforms and use different silicon. The Ultra 5 236V is built on Lunar Lake, a mobile architecture, while the Ultra 9 285 uses Arrow Lake-S, a desktop design. Both are fabricated on a 3 nm process at TSMC, according to the production data. The Ultra 9 285 contains 17,800 million transistors on a 243 mm² die; the database does not list a transistor count or die size for the Ultra 5 236V.

Core counts differ substantially. The Ultra 5 236V has 8 cores and 8 threads, while the Ultra 9 285 has 24 cores and 24 threads. Neither chip supports simultaneous multithreading, so threads equal cores in both cases. The Ultra 9 285 runs a 2.50 GHz base clock and boosts to 5.60 GHz. The Ultra 5 236V starts at 2.10 GHz and boosts to 4.70 GHz. Thermal design power reflects the platform split: 17 watts for the mobile part versus 65 watts for the desktop part.

Cache hierarchies diverge at the L2 and L3 levels. Both chips use 192 KB of L1 cache per core. The Ultra 5 236V carries 2.5 MB of L2 per core and 8 MB of shared L3. The Ultra 9 285 raises L2 to 3 MB per core and L3 to 36 MB shared. The additional L3 capacity, combined with more cores, explains much of the multi-threaded benchmark advantage.

Memory support also separates the two. The Ultra 9 285 supports DDR5 with a dual-channel memory bus and a recorded bandwidth of 102.4 GB/s. The Ultra 5 236V lists memory support as dependent on the motherboard, with a dual-channel bus but no bandwidth figure in the database. The Ultra 9 285 supports ECC memory; the Ultra 5 236V does not. PCIe connectivity differs as well, with the Ultra 9 285 offering Gen 5 over 20 CPU lanes versus Gen 5 over 4 CPU lanes for the Ultra 5 236V.

Integrated graphics and sockets reflect their segments. The Ultra 5 236V uses Arc 130V graphics and sits in Intel BGA 2833, a soldered mobile socket. The Ultra 9 285 uses Arc Xe-LPG Graphics with 64 execution units and fits Intel Socket 1851. The Ultra 5 236V launched on 2024-09-23, while the Ultra 9 285 records a launch date of 2024-12-31. The Ultra 9 285 has a launch MSRP of $579; the Ultra 5 236V has no launch MSRP in the database. Neither processor has an unlocked multiplier.

The Verdict

The data presents a clear performance hierarchy. The Ultra 9 285 outperforms the Ultra 5 236V in every recorded benchmark, with deltas ranging from 20.2% in single-thread PassMark to 76.5% in integer math. The desktop part also holds a 95th percentile ranking among all CPUs in the database, versus the 75th percentile for the mobile chip. Average benchmark scores reinforce this: 75,488 for the Ultra 9 285 versus 21,952 for the Ultra 5 236V.

The Ultra 5 236V is not without merit, but its strengths lie outside raw compute. Its 17 watt TDP positions it for mobile platforms where power efficiency and battery life take priority over peak throughput. The 8-core, 8-thread configuration with a 4.70 GHz boost is sufficient for everyday workloads, and the integrated Arc 130V graphics provide a baseline GPU for a thin-and-light system. The single-thread PassMark gap of 20.2% is the closest margin in the entire dataset, suggesting that for lightly threaded tasks, the Ultra 5 236V is not far behind.

The Ultra 9 285 is the choice for desktop systems that need maximum multi-threaded performance. Its 24 cores, 36 MB of L3 cache, and 5.60 GHz boost clock deliver 68.1% higher Cinebench R23 multicore scores and 72.9% higher floating point math results. ECC memory support and 20 PCIe Gen 5 lanes make it suitable for workstation-class builds. The 65 watt TDP is modest for a 24-core desktop processor, which means cooling requirements remain manageable.

Selection depends entirely on the platform. The Ultra 5 236V is a mobile processor on a BGA socket, so it cannot be installed in a desktop motherboard. The Ultra 9 285 is a desktop processor on Socket 1851, so it cannot be used in a laptop. The benchmark deltas are useful for understanding the performance envelope of each design, but the socket and market segment differences mean buyers will choose based on form factor first.

Where Each One Wins

The Intel Core Ultra 9 285 wins in every measured performance category. Its largest advantages appear in integer math (76.5%), floating point math (72.9%), data encryption (72.2%), data compression (70.7%), and random string sorting (70.6%). These workloads all benefit from the 24-core configuration and the 36 MB L3 cache. The Cinebench suite, which stresses sustained all-core rendering, shows a consistent 68.1% delta across R15, R20, and R23, both single-core and multi-core variants. For content creation, scientific computing, or any task that scales with core count, the Ultra 9 285 is the stronger option.

The Intel Core Ultra 5 236V does not win any recorded benchmark, but its profile suits a different class of usage. The 17 watt TDP makes it appropriate for compact mobile systems where thermal limits are tight and sustained full-load operation is rare. The 8-core design with a 4.70 GHz boost provides responsive single-thread behavior for interactive applications, and the PassMark single-thread score of 3,893 is only 20.2% behind the Ultra 9 285. The integrated Arc 130V graphics, combined with the low power envelope, suggests a platform designed for portability rather than peak compute.

Workload type matters more than raw score deltas in some cases. For short bursts of activity, such as application launches or light compilation, the Ultra 5 236V's 4.70 GHz boost clock keeps it competitive. For extended rendering, simulation, or data processing, the Ultra 9 285's additional 16 cores and 28 MB of extra L3 cache create an insurmountable gap. The database shows no scenario where the Ultra 5 236V closes the multi-core deficit, and the 95th versus 75th percentile ranking places the two chips in different performance tiers overall.

Platform constraints ultimately define the use case. The Ultra 5 236V is a soldered mobile processor, so it belongs in laptops and mini-PCs that prioritize battery life and low heat output. The Ultra 9 285 is a desktop processor with ECC support, 20 PCIe Gen 5 lanes, and a 102.4 GB/s memory bandwidth, so it belongs in workstations and high-performance desktops. Each chip wins within its intended form factor, even if the benchmark data shows one dominating the other in raw compute.
