Intel Core 7 240H vs Intel Core Ultra 7 270K Plus Comparison

The Verdict

The benchmark data presents a decisive result: the Intel Core Ultra 7 270K Plus wins all 17 recorded head-to-head comparisons against the Intel Core 7 240H. No single test in the database favors the mobile chip. The Core Ultra 7 270K Plus sits at the 96th percentile of all CPUs, while the Core 7 240H is at the 82nd percentile. The average benchmark score for the Core Ultra 7 270K Plus is 93,785, roughly three times the 31,483 average of the Core 7 240H.

The Core 7 240H is a mobile processor on Intel BGA 1744, designed for laptops, with a 45 TDP and a boost clock of 5.20. The Core Ultra 7 270K Plus is a desktop part on Intel Socket 1851, with a 125 TDP, a boost clock of 5.50, and an unlocked multiplier. The data indicates a clear performance hierarchy: the desktop part dominates in every workload category, from single-threaded tasks to heavily threaded rendering.

A buyer constrained to a mobile platform should expect the Core 7 240H to deliver competitive results within its class, as its nearest rivals include the Intel Core Ultra 3 205 and AMD Ryzen 9 5980HX, both with near-identical average scores. The Core Ultra 7 270K Plus, by contrast, competes against server-class parts like the Intel Xeon 6520P and AMD EPYC 4564P, with delta percentages of 0 and -1.5 respectively. The database clearly separates these two processors into different performance tiers. The Core Ultra 7 270K Plus is the choice for any workload where raw throughput matters. The Core 7 240H remains relevant only where the mobile form factor is mandatory.

Architecture Differences

The two processors come from different Intel design lineages. The Core 7 240H uses the Raptor Lake architecture, specifically the Raptor Lake-H refresh, built on Intel's 10 nm process. The Core Ultra 7 270K Plus belongs to the Arrow Lake Refresh family within the Core Ultra Series 2, fabricated on a 3 nm node by TSMC. The die size for the Ultra 7 is 243 mm², containing 17,800 million transistors.

Core counts differ substantially. The Core 7 240H has 10 cores and 16 threads, while the Core Ultra 7 270K Plus has 24 cores and 24 threads. The Ultra 7 uses a design without hyperthreading, as its thread count equals its core count. The mobile chip has a base clock of 2.50 GHz and boosts to 5.20 GHz. The desktop chip starts at 3.70 GHz and reaches 5.50 GHz.

Cache hierarchies are also different. The Core 7 240H provides 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The Core Ultra 7 270K Plus provides 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The larger per-core caches on the desktop part align with its higher core count and larger physical die.

Memory support diverges. The Core 7 240H supports both DDR4 and DDR5 in a dual-channel configuration. The Core Ultra 7 270K Plus supports DDR5 only, also dual-channel, with a recorded memory bandwidth of 115.2 GB/s. ECC memory is supported on the Ultra 7 but not on the mobile chip. PCIe connectivity differs as well: the Core 7 240H provides Gen 5 with 8 lanes from the CPU, while the Ultra 7 provides Gen 5 with 20 lanes.

Integrated graphics differ in branding. The Core 7 240H uses Iris Xe Graphics with 64 execution units. The Core Ultra 7 270K Plus uses Arc Xe-LPG Graphics, also with 64 execution units. Both are integrated solutions, though the database does not provide comparative graphics benchmarks. The Ultra 7 has an unlocked multiplier, enabling overclocking, while the Core 7 240H does not. Both processors are listed as Active in production status.

Where Each One Wins

The head-to-head results show zero wins for the Core 7 240H. Every recorded benchmark, regardless of workload type, favors the Core Ultra 7 270K Plus. This makes a use-case split difficult to construct from wins alone. Instead, the data supports a split by platform and by the magnitude of the deficit.

The Core 7 240H is a mobile processor. Its 45 TDP and BGA 1744 socket place it in laptops. Within that context, the recorded scores show it performs at a level comparable to its nearest rivals: the Intel Core Ultra 3 205, the AMD Ryzen 9 5980HX, and the Intel Core Ultra 5 225H all sit within 0.1 percent of its average score. The Core 7 240H would be the relevant choice for a system that requires the mobile form factor.

The Core Ultra 7 270K Plus wins every single-threaded test by a margin between 25.4 and 29.7 percent. It wins every multi-threaded test by margins ranging from 54.3 to 83.4 percent. The smallest single-threaded gap appears in PassMark single-thread, where the Ultra 7 scores 5,068 against 3,782, a delta of -25.4 percent. The largest multi-threaded gap appears in PassMark find prime numbers, where the Ultra 7 scores 615 against 102, a delta of -83.4 percent.

The data indicates that the Ultra 7 is particularly strong in integer math, floating-point math, and data compression. These are workloads that scale with core count and memory bandwidth. The desktop part's 24 cores, 36 MB of L3, and 115.2 GB/s memory bandwidth provide the structural advantage. The mobile chip's 10 cores and 24 MB of L3 cannot close the gap.
