These margins are extremely tight, all within roughly one-third of one percent, indicating that the Core Ultra 7 256V sits in a densely populated performance band.

Where Each One Wins

The Intel Core Ultra 7 256V demonstrates its strongest showing in single-threaded workloads relative to its nearest rivals. Its single-core Cinebench R23 score of 1,877.5 and Geekbench singlecore score of 1,990 indicate robust per-thread performance, which typically benefits responsive application behavior and lightly threaded tasks.

The PassMark data for the Intel part reveals specific strengths. Floating point math at 58,576 exceeds integer math at 43,358 by a substantial margin, suggesting the architecture handles floating-point-heavy code efficiently. Data compression at 184,985 is the highest single PassMark subscore recorded, indicating strong throughput for compression workloads. Data encryption at 13,998 is comparatively modest, and prime number finding at 192 is the lowest subscore, reflecting the test's sensitivity to integer division and branch handling.

The AMD Ryzen Embedded 9900X cannot be assigned wins in any benchmark category because the database contains no recorded scores for it. Its specifications, however, point to capabilities that would likely favor heavily threaded workloads if measured. With 12 cores and 24 threads, it offers more than double the thread count of the Intel part's 8 cores and 8 threads. Its boost clock of 5.60 GHz exceeds the Intel part's 4.80 GHz, and its 64 MB L3 cache dwarfs the Intel part's 12 MB shared L3 cache. The AMD processor also supports ECC memory, a feature absent from the Intel part.

For workloads that depend on large on-die caches, the AMD processor's 64 MB L3 cache provides a structural advantage. The Intel processor's larger per-core L1 cache (192 KB per core versus 80 KB per core) and larger per-core L2 cache (2.5 MB per core versus 1 MB per core) may benefit latency-sensitive single-threaded code, but the AMD part's massive shared L3 cache is designed for data reuse across many threads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen Embedded 9900X uses the Granite Ridge codename based on the Zen 5 architecture, built on a 4 nm process at TSMC. It integrates 16,630 million transistors across a dual-chiplet design with two dies, each measuring 70.6 mm². The Intel Core Ultra 7 256V uses the Lunar Lake architecture, built on a 3 nm process, also at TSMC. The Intel part's transistor count and die size are not recorded in the database.

Core and thread configurations differ sharply. The AMD processor provides 12 cores and 24 threads, supporting simultaneous multithreading. The Intel processor provides 8 cores and 8 threads with no SMT capability, as indicated by equal core and thread counts. This means the AMD part can execute twice as many threads concurrently, which directly impacts multi-threaded throughput potential.

Cache hierarchies follow different strategies. The AMD processor allocates 80 KB of L1 cache per core and 1 MB of L2 cache per core, then pools 64 MB of L3 cache. The Intel processor allocates 192 KB of L1 cache per core and 2.5 MB of L2 cache per core, with 12 MB of shared L3 cache. Per-core cache is larger on the Intel part, but the AMD part's total L3 capacity is over five times larger. The Intel part's memory bandwidth is not recorded; the AMD part lists 89.6 GB/s over dual-channel DDR5.

Clock speeds also differ. The AMD processor has a base clock of 4.40 GHz and a boost clock of 5.60 GHz. The Intel processor has a base clock of 2.20 GHz and a boost clock of 4.80 GHz. The AMD part's base clock is exactly double the Intel part's base clock. Power envelopes diverge dramatically: the AMD processor has a TDP of 120 watts, while the Intel processor has a TDP of 17 watts. This sevenfold difference reflects their intended markets: desktop versus mobile.

Platform support differs as well. The AMD processor uses AMD Socket AM5 and exposes PCIe Gen 5 with 24 lanes from the CPU. The Intel processor uses Intel BGA 2833, a soldered mobile package, and exposes PCIe Gen 5 with only 4 lanes from the CPU. The AMD part has an unlocked multiplier, while the Intel part is locked. Integrated graphics also differ: the AMD processor carries Radeon Graphics, while the Intel processor carries Arc 140V.

The AMD processor's memory support is listed as DDR5, and it supports ECC memory. The Intel processor's memory support is listed as dependent on the motherboard, and it does not support ECC memory. Release dates place the Intel part first, launched on 2024-09-23, while the AMD part launched on 2025-10-06. Both are listed as Active in production status.

The Verdict

The recorded data supports a clear split based on workload type and platform requirements. The Intel Core Ultra 7 256V has measured performance data placing it at the 75th percentile of all CPUs in the database, with an average score of 21,112. Its nearest rivals cluster within 0.3% of its score, indicating that it performs in line with established mid-range processors like the AMD Ryzen 5 7530U, AMD Ryzen 5 5600G, Intel Core i3-1220P, and Intel Core Ultra 7 155U.

The AMD Ryzen Embedded 9900X has no benchmark scores in the database, so its measured performance cannot be stated. Its specifications, however, describe a processor aimed at a different role. A 120-watt TDP, 12 cores with 24 threads, a 5.60 GHz boost clock, and 64 MB of L3 cache indicate a part designed for sustained multi-threaded compute in embedded or desktop contexts. The Intel part's 17-watt TDP, 8 cores with 8 threads, and 4.80 GHz boost clock describe a mobile-focused processor optimized for efficiency within a constrained power budget.

The percentile data reinforces this distinction. The Intel part sits at the 75th percentile, meaning it outperforms three-quarters of all CPUs in the database. The AMD part sits at the 50th percentile with no recorded average score, which reflects missing measurements rather than a performance verdict. Until benchmark data is recorded for the AMD processor, any direct performance ranking between these two specific units remains unavailable from the database.

For users selecting between these two processors, the data supports the Intel part for scenarios requiring verified performance within a 17-watt envelope, particularly in mobile or low-power systems. The AMD part's specifications support scenarios requiring high thread counts, large shared cache, ECC memory support, and an unlocked multiplier in a 120-watt desktop or embedded platform. The choice hinges on whether measured efficiency at low power or specified multi-threaded capacity at higher power is the priority.
