The Ultra 9 285 lists a transistor count of 17,800 million and a die size of 243 mm². The Ultra 7 256V does not have recorded transistor or die size data in the database. The Ultra 9 285 also specifies 102.4 GB/s of memory bandwidth, while the Ultra 7 256V has no memory bandwidth figure listed.

Memory support differs: the Ultra 9 285 supports DDR5, while the Ultra 7 256V's memory support is listed as dependent on the motherboard. Both use dual-channel memory buses. PCIe connectivity also differs: the Ultra 9 285 offers Gen 5 with 20 lanes (CPU only), while the Ultra 7 256V offers Gen 5 with 4 lanes (CPU only).

Integrated graphics differ as well. The Ultra 7 256V uses Arc 140V, while the Ultra 9 285 uses Arc Xe-LPG Graphics 64EU. The market segments are distinct: the Ultra 7 256V is aimed at mobile platforms, and the Ultra 9 285 targets desktop systems.

The sockets are incompatible. The Ultra 7 256V uses Intel BGA 2833, a soldered mobile socket. The Ultra 9 285 uses Intel Socket 1851, a desktop socket. The Ultra 9 285 has a 65 W TDP, while the Ultra 7 256V has a 17 W TDP. Base clocks are 2.50 GHz for the Ultra 9 285 and 2.20 GHz for the Ultra 7 256V.

The Verdict

The data is unambiguous. The Intel Core Ultra 9 285 outperforms the Intel Core Ultra 7 256V in every single benchmark recorded in the database. The win count is 17 to 0. The Ultra 9 285 also occupies a much higher position in the overall CPU distribution: 95th percentile versus 75th percentile.

The average benchmark score difference is substantial. The Ultra 9 285 averages 75,488, which is roughly 3.6 times the Ultra 7 256V's average of 21,112. This places the Ultra 9 285 among server-class and high-end desktop parts, with nearest rivals including AMD EPYC processors. The Ultra 7 256V sits near mid-range mobile and desktop chips such as the AMD Ryzen 5 7530U and Intel Core i3-1220P.

For workloads that depend on multithreaded throughput, the Ultra 9 285 is the clear choice. Its 24 cores and 36 MB of L3 cache deliver margins exceeding 65% in every multithreaded test. For workloads that are lightly threaded, the Ultra 9 285 still leads, though the gap narrows to 17.5% in PassMark single-thread. The Ultra 7 256V's 17 W TDP and mobile socket make it suitable for compact, power-constrained systems, but the performance data shows no benchmark category where it takes the lead.

The specification differences reinforce the benchmark results. The Ultra 9 285 offers more cores, more cache, higher clocks, ECC support, and more PCIe lanes. The Ultra 7 256V offers lower power consumption and a smaller physical footprint, but the recorded performance metrics do not favor it anywhere.

Where Each One Wins

The benchmark data shows zero wins for the Ultra 7 256V across all 17 recorded tests. The Ultra 9 285 wins every category.

The Ultra 9 285's largest advantages appear in Cinebench R23 multicore (78.8% ahead), PassMark integer math (73.7% ahead), and Cinebench R23 single-core (72.8% ahead). It also leads by roughly 70% in PassMark data compression, data encryption, and floating point math. The smallest advantage is in PassMark single-thread at 17.5%.

The Ultra 7 256V does not win any benchmark, but its relative positioning suggests closer competition in lightly threaded tests. The 17.5% gap in PassMark single-thread is far smaller than the 65% to 78% gaps in multithreaded workloads. The Ultra 7 256V also has a much lower TDP at 17 W versus 65 W, which may matter for thermal or battery constraints, though the database does not include power or efficiency benchmarks to quantify that trade-off.

For any use case that relies on CPU compute throughput, the recorded data indicates the Ultra 9 285 is the stronger part. For highly mobile or low-power systems where the Ultra 7 256V's socket and TDP fit, the performance penalty is measurable but smallest in single-thread scenarios. The database records no scenario where the Ultra 7 256V takes the lead.
