Where Each One Wins

The benchmark data is unambiguous: the Intel Core i9-12900K wins every single head-to-head test recorded. The closest contest is in single-thread performance, where the Intel part scores 4,136 versus the AMD’s 3,128, a delta of -24.4%. The largest gap appears in the prime number finding test, where Intel scores 147 versus AMD’s 49, a staggering -66.7% difference.

Despite the sweeping losses, the AMD Ryzen 7 170 has a clear purpose. Its 35 watt TDP is a fraction of the Intel’s 125 watts, making it a logical choice for mobile workstations and ultraportable laptops. The Ryzen also offers 20 PCIe Gen 4 lanes, which can be advantageous for connecting multiple storage devices or peripherals in a compact system. Its Radeon 680M integrated graphics provide a more capable gaming baseline for a device with no discrete GPU, even though the database does not include direct graphics benchmarks.

The Intel Core i9-12900K, meanwhile, is the performance king. It dominates in every compute metric, from floating point math (105,471 vs 44,979) to data compression (537,341 vs 265,920). For users who need maximum processing power in a desktop, this is the clear winner. The Intel chip also has a higher boost clock (5.20 GHz vs 4.75 GHz) and a larger L3 cache (30 MB vs 16 MB), which helps in latency-sensitive workloads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 170 uses the Zen 3+ architecture, codenamed Rembrandt-R, built on a 6 nm process at TSMC. It is a monolithic design with 8 cores and 16 threads, featuring 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The chip is designed for the AMD Socket FP7 platform, targeting mobile devices.

The Intel Core i9-12900K uses the Alder Lake architecture, specifically Alder Lake-S, built on Intel’s 10 nm process. This is a hybrid design with 16 cores and 24 threads, combining performance cores and efficiency cores. It has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and a larger 30 MB shared L3 cache. The Intel part uses the Intel Socket 1700 platform for desktop systems.

Memory support differs here as well. The AMD Ryzen 7 170 supports only DDR5 memory, while the Intel Core i9-12900K supports both DDR4 and DDR5. Both run dual-channel memory buses with the same theoretical bandwidth of 76.8 GB/s. The AMD chip includes ECC memory support, as does the Intel part, which is notable for workstation reliability.

The integrated graphics also reflect their target segments. AMD’s Radeon 680M is a modern iGPU based on RDNA architecture, while Intel’s UHD Graphics 770 is a more basic solution. Neither processor has a multiplier unlocked on the AMD side, but the Intel Core i9-12900K does have an unlocked multiplier for overclocking.

Specification Differences

The core counts are the most obvious split: 8 cores and 16 threads on the AMD versus 16 cores and 24 threads on the Intel. The base clocks are identical at 3.20 GHz for both parts, but the Intel boost clock reaches 5.20 GHz compared to the AMD’s 4.75 GHz.

The TDP difference is stark: 35 watts for the AMD Ryzen 7 170 versus 125 watts for the Intel Core i9-12900K. This reflects the mobile versus desktop market segmentation. The AMD chip is listed as a mobile processor, while the Intel chip is a desktop part.

Process node and foundry also differ. AMD uses a 6 nm process from TSMC, while Intel uses a 10 nm process from its own fabs. The die sizes are close, with AMD at 210 mm² and Intel at 215 mm². Cache configurations differ as noted, with Intel offering larger per-core L2 and a larger shared L3.

The socket is another key difference: AMD Socket FP7 for the Ryzen, Intel Socket 1700 for the Core i9. The PCIe support differs in generation and lane count, with AMD offering Gen 4 with 20 lanes and Intel offering Gen 5 with 16 lanes. The Intel part has a launch MSRP of $599, while the AMD part has no listed launch MSRP.

Head-to-Head Benchmarks

The most lopsided result in the database is the PassMark find prime numbers test. The Intel Core i9-12900K scores 147, while the AMD Ryzen 7 170 scores 49, a delta of -66.7%. This test heavily favors the Intel’s higher core count and boost clock.

Floating point math shows a similar trend. Intel scores 105,471 versus AMD’s 44,979, a -57.4% delta. In physics calculations, Intel’s 2,219 beats AMD’s 890, a -59.9% difference. The random string sorting test sees Intel at 57,094 versus AMD’s 27,804, a -51.3% gap.

The data compression test is one of the largest absolute gaps: Intel scores 537,341, while AMD manages 265,920, a -50.5% delta. Data encryption follows with Intel at 29,579 and AMD at 16,078, a -45.6% difference. Extended instructions show Intel at 33,682 versus AMD’s 18,107, a -46.2% gap.

Multithread performance is decisive: Intel’s 41,213 dwarfs AMD’s 20,760, a -49.6% delta. Integer math sees Intel at 139,090 versus AMD’s 79,738, a -42.7% difference. The single-thread test is the closest, with Intel at 4,136 and AMD at 3,128, a -24.4% delta. The database records 11 wins for Intel and 0 for AMD across all head-to-head tests.

The average benchmark scores tell a slightly different story. The AMD Ryzen 7 170 averages 43,689, which is higher than the Intel’s 42,335. This is because the AMD part’s benchmark set includes different tests, and its nearest rivals include the AMD Ryzen 7 PRO 7745 and the AMD Ryzen AI 9 465. The Intel’s nearest rivals include the Intel Core i9-12950HX and the AMD Ryzen 5 7400, showing how each CPU compares within its own performance tier.

In practical terms, the Intel Core i9-12900K is the superior processor for any compute-intensive task. The data shows it leads by significant margins in every recorded workload. The AMD Ryzen 7 170, however, offers a compelling package for mobile users who prioritize battery life and low heat output, and its integrated Radeon 680M graphics provide a stronger iGPU solution for casual gaming and media tasks. The choice between the two comes down to platform and power budget rather than raw performance, where the Intel part is the undisputed leader.
