AMD Ryzen 7 7800X3D vs Intel Core i7-12800HX Comparison

Head-to-Head Benchmarks

The data shows a clear split between heavily threaded workloads and lighter, latency-sensitive tasks. The Intel Core i7-12800HX dominates in multi-core rendering and math throughput, while the AMD Ryzen 7 7800X3D takes the lead in a broader range of tests, including physics and encryption.

The largest single win for Intel comes in Cinebench R23 multi-core, where the i7-12800HX scores 22456 against the Ryzen 7 7800X3D's 16817, a 33.5% advantage. That is a massive margin in a workload that scales with core count and sustained power. The same pattern shows in Cinebench R15 multi-core, with Intel ahead by 17.5% (3383 vs 2878.5). PassMark floating point math also heavily favors Intel: 82122 versus 61187, a 34.2% lead. These are not small edges; they represent a full performance tier in rendering and scientific compute.

Intel also wins in 3DMark max threads, scoring 9119 against 7967, a 14.5% advantage. That test likely reflects the i7-12800HX's 16 cores and 24 threads versus the Ryzen's 8 cores and 16 threads. In single-threaded Cinebench R23, Intel is ahead by 5.8% (1812 vs 1713), and in 3DMark single thread, Intel leads by 4.2% (999 vs 959). PassMark integer math goes to Intel by 6.1% (109968 vs 103639). The i7-12800HX also edges out the Ryzen in data compression, 387535 vs 384669, a slim 0.7% margin.

The Ryzen 7 7800X3D fights back in several key areas. Its most dominant win is in PassMark physics, where it scores 3522 versus Intel's 1743, a 50.5% advantage. That is a massive difference, and it suggests the Ryzen's architecture handles physics simulation far more efficiently. PassMark find prime numbers also goes heavily to AMD: 324 versus 108, a 66.7% lead. PassMark extended instructions favor the Ryzen by 18.5% (29166 vs 23760), and PassMark multithread goes to AMD by 7.9% (34293 vs 31585).

In lighter 3DMark thread counts, the Ryzen takes the lead: 16 threads by 1.1% (7980 vs 7889), 8 threads by 3.8% (6539 vs 6292), and 4 threads by 1.3% (3684 vs 3636). The Ryzen also wins Cinebench R15 single core by 7.6% (281.5 vs 260), which is notable because Intel wins the newer R23 single-core test. PassMark data encryption goes to AMD by 1.7% (22346 vs 21972), and random string sorting goes to AMD by 6.5% (45418 vs 42453). Finally, PassMark single thread (both entries) goes to AMD by 1.3% (3759 vs 3711).

Overall, the head-to-head record is 12 wins for AMD and 9 for Intel. However, the magnitude of Intel's multi-core wins is often larger than AMD's margins in its own victories.

Where Each One Wins

The Intel Core i7-12800HX is the clear choice for sustained, heavily threaded productivity. If you are rendering with Cinebench, doing floating-point math, or running any workload that uses every core for a long time, the i7-12800HX has a decisive advantage. The 33.5% lead in Cinebench R23 multi-core and 34.2% lead in PassMark floating point math are the headline numbers here. For integer math, which is common in compilation and data processing, Intel is ahead by 6.1%. If the task is data compression, Intel holds a narrow 0.7% edge.

The AMD Ryzen 7 7800X3D wins in scenarios that rely on physics simulation, encryption, and extended instruction sets. The 50.5% lead in PassMark physics is the most striking, and the 66.7% lead in prime number finding suggests a strong advantage in certain algorithmic workloads. For encryption, AMD is 1.7% ahead. For random string sorting, AMD leads by 6.5%. In general multithreaded PassMark scoring, the Ryzen is 7.9% ahead, which indicates that the AMD chip manages a mix of workloads better than the raw core count suggests.

For single-threaded performance, the results are mixed. Intel wins Cinebench R23 single core by 5.8% and 3DMark single thread by 4.2%, but AMD wins Cinebench R15 single core by 7.6% and PassMark single thread by 1.3%. The Ryzen also wins 3DMark at 4, 8, and 16 thread counts, which points to stronger per-core efficiency in gaming-like scenarios.

The Verdict

Choose the Intel Core i7-12800HX if your priority is raw multi-core throughput for rendering, floating-point math, or integer-heavy workloads. The data is unambiguous: Intel leads by 33.5% in Cinebench R23 multi-core and by 34.2% in PassMark floating point math. It also wins in 3DMark max threads by 14.5%, which shows its core count advantage under full load. If you are running Cinebench, compiling code, or doing scientific computing, the i7-12800HX is the stronger pick.

Choose the AMD Ryzen 7 7800X3D if your workload involves physics simulation, cryptography, or extended instruction sets. The 50.5% lead in PassMark physics and the 66.7% lead in prime number finding are the largest margins in the entire comparison. The Ryzen also wins in PassMark multithread by 7.9% and in random string sorting by 6.5%, suggesting it handles a wider mix of tasks more gracefully. For gaming-like 3DMark workloads at 4, 8, and 16 threads, the Ryzen holds a consistent, if modest, lead.

The overall average benchmark scores favor Intel (33875 vs 33079), but the Ryzen wins more individual tests (12 vs 9). The Intel chip has more cores and threads, while the AMD chip has a much larger L3 cache (96 MB vs 25 MB) and a smaller, more advanced 5 nm process node. The Ryzen also supports ECC memory and has a higher memory bandwidth figure. If you need desktop compatibility, DDR5-only memory, and ECC, the Ryzen is the practical choice. If you need a mobile processor with massive multi-core capability, the i7-12800HX is the one the data supports.
