Intel Core i7-12800HX

The Intel Core i7-12800HX is a 16-core, 24-thread mobile processor in Intel’s Core 12th Gen family, built on the Alder Lake-HX architecture and Intel’s 10 nm process. Its base clock is 2000 MHz, its boost clock is 4.80 GHz, and its average benchmark score is 34,136, which places it at the 88th percentile of all CPUs in the database. The processor had a launch MSRP of $457.

Benchmark Performance

The aggregate performance of the Core i7-12800HX sits inside a very tight cluster of rivals. Its average benchmark score of 34,136 is 0.1% behind the Intel Core i5-13500 (34,175), 0.4% ahead of the AMD Ryzen 7 7735H (33,997), 0.5% behind the AMD Ryzen 7 7700X (34,313), and 1.2% ahead of the Intel Core 7 250H (33,725). No rival in this nearest group is separated by more than 1.2%, so the i7-12800HX is effectively competing in a narrow band of aggregate performance.

Multi-threaded benchmarks give a clearer picture of where the processor’s strength lies. In Cinebench R23 it scores 26,847 multi-core, in Cinebench R20 it scores 11,275 multi-core, and in Cinebench R15 it scores 2,706 multi-core. The PassMark multithread score is 31,585, while PassMark integer math reaches 109,968 and floating-point math reaches 82,122. The 3DMark thread tests add another layer: the 16-thread score is 7,889 and the max-thread score is 9,119. These results are consistent with a 16-core, 24-thread part that handles parallel workloads well.

Single-thread performance is also competitive. Cinebench R23 single-core is 3,790, R20 single-core is 1,591, and R15 single-core is 381. PassMark single-thread is 3,711, and 3DMark single-thread is 999. The 3DMark scaling sequence shows how the core count is utilized: 1,943 at 2 threads, 3,636 at 4 threads, 6,292 at 8 threads, 7,889 at 16 threads, and 9,119 at max threads. The jump from 999 single-thread to 1,943 two-thread shows that the architecture extracts meaningful additional performance as soon as a second thread is available.

Secondary PassMark results fill out the throughput profile. Data compression scores 387,535, random string sorting scores 42,453, data encryption scores 21,972, and extended instructions score 23,760. The physics test records 1,743 and the find-prime-numbers test records 108. These are not headline numbers, but they indicate that the processor is not single-specialized; its throughput is spread across a range of integer, floating-point, and memory-related workloads.

Who Should Consider It

Users with multi-threaded creation workloads are the clearest fit. The Cinebench R23 multi-core result of 26,847 and the R20 multi-core result of 11,275 point to strong rendering-style throughput, and the PassMark multithread score of 31,585 reinforces that conclusion. For a mobile processor, the presence of 16 cores and 24 threads gives applications that scale across cores a substantial resource to draw on.

Office and productivity users also have relevant data. PassMark data compression at 387,535 and random string sorting at 42,453 indicate that data-heavy office tasks involving archives, sorting, or large structured data will have solid throughput. The encryption score of 21,972 is present but not exceptional within the broader data set. Users who run a mix of parallel and latency-sensitive tasks will benefit from the combination of a 3,790 Cinebench R23 single-core score and a 26,847 multi-core score.

For gaming, the CPU-level story is defined by the 3DMark thread scores. The 999 single-thread score, 1,943 two-thread score, 3,636 four-thread score, and 6,292 eight-thread score show scaling across the core counts that modern games may use. The max-thread score of 9,119 indicates headroom for highly threaded workloads. The data does not include game-specific frame-rate benchmarks, so this should be read as a processor throughput indication rather than a gaming performance projection.

Power and Thermals

The Core i7-12800HX has a 55 W TDP. That number places it in the high-performance mobile class rather than the low-power ultraportable class. A processor with 16 cores, 24 threads, and a 4.80 GHz boost clock in a 55 W envelope requires a cooling solution capable of sustained heat removal under heavy load. The integrated UHD Graphics 770 is part of the same package, so the cooling solution also needs to account for iGPU activity.

The physical background is provided by the manufacturing data: the processor is built on Intel’s 10 nm node and has a die size of 215 mm². No specific cooler size or thermal solution rating is included in the fact pack, so the 55 W TDP is the primary class-defining number for thermal expectations. The combination of a 10 nm process, a 215 mm² die, and a 55 W TDP frames the i7-12800HX as a mobile processor that trades some thermal headroom for high core count and boost potential.

How It Compares

Intel Core i5-13500: The i7-12800HX trails this rival by 0.1%, with an average score of 34,136 against 34,175. This is the closest comparison in the rival set, effectively a statistical tie in aggregate benchmark terms.

Platform and Compatibility

The Core i7-12800HX uses the Intel BGA 1964 socket, which is a mobile board-mounted package. The upgrade path is therefore tied to the laptop’s motherboard design rather than a user-swappable socket. The processor is in the mobile market segment, its production status is Active, and its release date is May 9, 2022.

Memory support is dual-channel DDR4 and DDR5, with no ECC support. The cache hierarchy consists of 80 KB of L1 per core, 1.25 MB of L2 per core, and 25 MB of shared L3 cache. The CPU provides PCIe Gen 5 with 20 lanes, and the fact pack notes that these lanes are CPU-only. For platform connectivity, this means the processor itself supplies a Gen 5 lane count of 20, while additional platform-level lane details are not specified.

The integrated UHD Graphics 770 is part of the processor package, and the multiplier is unlocked. The part carries the part number SRLGL and is built on the Alder Lake-HX codename. For a mobile system, the Intel BGA 1964 socket, DDR4/DDR5 memory support, and CPU-only PCIe Gen 5 lanes define the boundaries of what the i7-12800HX can connect to and how the platform can be configured around it.
