Intel Core 7 240H vs Intel Core 7 251E Comparison

Head-to-Head Benchmarks

The Intel Core 7 240H and Intel Core 7 251E are hard to compare directly because the database contains no overlapping benchmark scores. The Core 7 240H has a full set of measured results across Cinebench and Passmark tests. The Core 7 251E has no recorded benchmark scores at all, leaving its average benchmark score at 0 and its percentile ranking at 50. This means the comparison is based on architectural and specification differences rather than head-to-head test results.

The Core 7 240H delivers a Cinebench R23 multi-core score of 15764 and a single-core score of 1719. Its Cinebench R20 results show 8562 multi-core and 1208 single-core. In Cinebench R15, it scores 2360 multi-core and 249 single-core. Passmark results include a multi-thread score of 23975, a single-thread score of 3782, integer math at 80396, floating point math at 58905, and data compression at 271774. The Core 7 240H sits at the 82nd percentile among all CPUs, with an average benchmark score of 31483. Its nearest rivals sit close by: the AMD Ryzen 9 5980HX averages 31495, the Intel Core Ultra 5 225H averages 31508, and the Intel Core i5-13500 averages 31510. The Core 7 240H trails those three by 0.1 percent, and it matches the Intel Core Ultra 3 205 at 31473.

Because the Core 7 251E has no benchmark results, there is no measured basis for declaring a winner in any compute test. The 251E's average score of 0 reflects missing data, not zero performance. The percentile field of 50 for the 251E cannot be compared to the 240H's 82nd percentile ranking, since one is derived from actual runs and the other is a placeholder from incomplete records.

Architecture Differences

The two processors come from different families. The Core 7 240H uses the Raptor Lake architecture with the Raptor Lake-H codename, and it belongs to the Core 7 (Raptor Lake Refresh) generation. The Core 7 251E uses the Bartlett Lake codename and belongs to the Core 7 (Bartlett Lake) generation. Both are built on a 10 nm process at Intel's foundry, but the die size differs: the 251E has a 257 mm² die, while the 240H has no recorded die size in the database.

Core counts diverge sharply. The 240H has 10 cores and 16 threads, while the 251E has 24 cores and 32 threads. That is a difference of 14 cores and 16 threads in favor of the 251E. Both use the same per-core cache structure: 80 KB of L1 per core and 2 MB of L2 per core. Shared L3 cache differs, with the 240H offering 24 MB and the 251E offering 36 MB, a 12 MB advantage for the 251E.

Clock behavior also differs. The 240H has a base clock of 2.50 GHz and a boost clock of 5.20 GHz. The 251E starts lower at 2.10 GHz base but boosts higher at 5.60 GHz. The thermal design power is 45 watts for the 240H and 65 watts for the 251E. The 251E carries a 20 watt higher TDP, which aligns with its desktop market segment and larger core count.

The integrated graphics differ as well. The 240H uses Iris Xe Graphics with 64 execution units. The 251E uses UHD Graphics 770. Memory support is identical on paper: both accept DDR4 and DDR5 in dual-channel configuration. The 251E has a recorded memory bandwidth of 89.6 GB/s, while the 240H has no bandwidth figure in the database. ECC memory support also differs: the 240H does not support ECC, while the 251E does.

PCIe lanes differ by a factor of two. The 240H provides Gen 5 with 8 lanes from the CPU. The 251E provides Gen 5 with 16 lanes from the CPU. Socket compatibility is entirely different: the 240H uses Intel BGA 1744, a mobile socket, while the 251E uses Intel Socket 1700, a desktop socket.

The table shows every field where the two differ in the database. The 251E leads in core count, thread count, boost clock, L3 cache, memory bandwidth, ECC support, PCIe lanes, and die size. The 240H leads in base clock, lower TDP, and has a substantially higher average benchmark score because it has actual measured results.

The Verdict

The data supports a clear split by platform. The Intel Core 7 240H is a mobile part with a 45 watt TDP, 10 cores, and 16 threads, and it has a proven benchmark record. Its average score of 31483 places it at the 82nd percentile among all CPUs, and its nearest rivals all land within 0.1 percent, which indicates a consistent level of performance for its class. The Core 7 251E is a desktop part with 24 cores, 32 threads, a 65 watt TDP, and no recorded benchmark scores. It cannot be ranked against the 240H with measured data, but its specification sheet shows a much larger core and thread count, more L3 cache, higher boost clock, and double the CPU PCIe lanes.

The socket difference is decisive. The 240H mounts on Intel BGA 1744, which is a soldered mobile socket. The 251E mounts on Intel Socket 1700, a standard desktop socket. These are not interchangeable platforms. A system designed for one cannot accept the other without a different motherboard and form factor.

The launch MSRP of the Core 7 251E is $384, while the launch MSRP of the Core 7 240H is $502. The database records these as launch figures, and they are the only pricing data available for these parts.

Where Each One Wins

The Core 7 240H wins on mobility and measured performance. It is the only one of the two with benchmark results, and those results put it at the 82nd percentile. Its 45 watt TDP makes it suitable for systems with tighter thermal limits. It also has a higher base clock at 2.50 GHz, which can help in lightly threaded tasks that rely on sustained base frequency. Its Iris Xe Graphics with 64 execution units is a more substantial integrated GPU than the UHD Graphics 770 in the 251E, based on the execution unit count and the naming difference.

The Core 7 251E wins on raw resource counts and desktop connectivity. Its 24 cores and 32 threads are more than double the 240H's 10 cores and 16 threads. Its 36 MB of L3 cache exceeds the 240H's 24 MB. Its boost clock of 5.60 GHz is higher than the 240H's 5.20 GHz. Its 16 PCIe Gen 5 lanes give it twice the CPU-attached lane count of the 240H's 8 lanes. It supports ECC memory, which the 240H does not. Its memory bandwidth is recorded at 89.6 GB/s, and its die size is recorded at 257 mm². It also carries a lower launch MSRP at $384 versus $502 for the 240H.

For a laptop or compact mobile system, the Core 7 240H is the only option between the two. For a desktop build where core count, L3 capacity, PCIe lane availability, and ECC memory matter, the Core 7 251E is the part that offers those features. The absence of benchmark data for the 251E means the performance advantage cannot be quantified, but the specifications show where it is built to excel.
