AMD Ryzen 7 260 vs Intel Core i9-12900K Comparison

The Verdict

The recorded data delivers a clear verdict: the Intel Core i9-12900K dominates the AMD Ryzen 7 260 across every single benchmark in the head-to-head comparison. The Intel part wins all 15 recorded tests, with the largest margins appearing in multi-threaded and floating-point workloads. The AMD Ryzen 7 260 is a mobile-focused 8-core processor designed for efficiency, while the Intel Core i9-12900K is a desktop flagship with 16 cores and significantly higher power limits. Based on the benchmark results, the i9-12900K is the choice for users who prioritize raw performance, especially in heavily threaded tasks. The Ryzen 7 260 is the choice for those who need a compact, lower-power platform (45 W TDP versus 125 W) and are willing to accept substantially lower scores in every measured workload. Neither chip is a compromise for its intended segment: the data shows the Intel part as a performance leader, while the AMD part trades performance for a dramatically lower thermal envelope.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 7 260 uses the Zen 4 architecture, codenamed Hawk Point, built on a 4 nm TSMC process with 25,000 million transistors on a 178 mm² die. It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.10 GHz. Its cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The chip supports DDR5 memory in a dual-channel configuration with a measured bandwidth of 89.6 GB/s, and it does not support ECC memory. It uses AMD Socket FP8, offers PCIe Gen 4 with 20 CPU lanes, and includes Radeon 780M integrated graphics. The multiplier is locked, and the market segment is mobile, with a release date of January 2025.

The Intel Core i9-12900K uses the Alder Lake architecture, codenamed Alder Lake-S, built on Intel's 10 nm process with a die size of 215 mm². It features 16 cores and 24 threads, with a base clock of 3.20 GHz and a boost clock of 5.20 GHz. The cache layout differs significantly: 80 KB of L1 per core, 1.25 MB of L2 per core, and 30 MB of shared L3. It supports both DDR4 and DDR5 memory in dual-channel mode, with a lower memory bandwidth of 76.8 GB/s, but it does support ECC memory. The socket is Intel Socket 1700, and it provides PCIe Gen 5 with 16 CPU lanes. Integrated graphics are UHD Graphics 770. The multiplier is unlocked, the market segment is desktop, and it launched in November 2021 with a launch MSRP of $599.

The architectural split is stark: AMD uses a newer, denser 4 nm process with fewer cores but higher memory bandwidth, while Intel uses a larger 10 nm die with more cores, more cache, and support for both DDR4 and DDR5. The Intel part also has a higher boost clock (5.20 GHz versus 5.10 GHz) and a much higher TDP (125 W versus 45 W), which explains its performance advantage in sustained workloads.

Head-to-Head Benchmarks

The head-to-head results show a consistent Intel advantage, but the margins vary by workload type. The largest gap appears in passmark_find_prime_numbers, where the Intel Core i9-12900K scores 147 versus the AMD Ryzen 7 260's 77, a 47.6% lead. This test is heavily dependent on integer arithmetic and core count, and the Intel part's 16 cores and 24 threads clearly dominate the AMD's 8 cores and 16 threads.

In floating-point math, the Intel part scores 105471 against 59462, a 43.6% lead. This is a massive difference and indicates that the Intel architecture handles FP workloads far more efficiently, likely due to its higher core count and larger L3 cache. Physics simulations show a similar pattern: Intel scores 2219 versus AMD's 1218, a 45.1% advantage, which is directly relevant for gaming physics and scientific computing.

Multi-core rendering tests follow the same trend. In Cinebench R23 multi-core, the Intel part scores 26125 versus 17211.5, a 34.1% lead. In Cinebench R15 multi-core, it scores 4057 versus 2747.5, a 32.3% lead. Data compression and encryption show 34.6% and 31.5% leads respectively, with Intel scoring 537341 and 29579 against AMD's 351517 and 20267. Integer math is 30.5% faster (139090 versus 96737), and the PassMark multi-thread score is 31.9% higher (41213 versus 28078).

Single-threaded performance is closer but still favors Intel. In Cinebench R23 single-core, Intel scores 2004.5 versus AMD's 1770.5, an 11.7% lead. Cinebench R15 single-core shows a 4.3% lead (289 versus 276.5). PassMark single-thread shows a 9.7% lead (4136 versus 3736). The smallest margin is in Cinebench R15 single-core, where the Intel part is only 4.3% ahead, indicating that AMD's Zen 4 cores are competitive per-thread, but the Intel chip still wins.

The only benchmark where the AMD part is not deeply behind is the single-core Cinebench R15 test, yet even there it loses. There is no workload in the recorded data where the Ryzen 7 260 takes a win. The Intel Core i9-12900K is faster in every test, with margins ranging from 4.3% to 47.6%.

A: No, the AMD Ryzen 7 260 does not support ECC memory. The Intel Core i9-12900K does support ECC memory, which is relevant for workstation or server use cases.

Q: Which processor has more cache?

A: The Intel Core i9-12900K has more L3 cache, with 30 MB shared, versus the AMD Ryzen 7 260's 16 MB shared. The Intel part also has larger L1 and L2 caches per core (80 KB and 1.25 MB versus 64 KB and 1 MB).

Q: Which processor has higher memory bandwidth?

A: The AMD Ryzen 7 260 has higher memory bandwidth at 89.6 GB/s, versus the Intel Core i9-12900K's 76.8 GB/s. However, the Intel part supports both DDR4 and DDR5, while the AMD part only supports DDR5.

Where Each One Wins

The Intel Core i9-12900K wins in every recorded benchmark, so the use-case split is based on the nature of the tasks and the platform constraints, not on performance victories for the AMD part.

The Intel Core i9-12900K is the clear choice for desktop users who need maximum compute performance. Its 16 cores and 24 threads, combined with a 5.20 GHz boost clock, make it the superior option for multi-threaded rendering, video encoding, data compression, encryption, and scientific computing. The 47.6% lead in prime number finding, 43.6% lead in floating-point math, and 45.1% lead in physics simulations show that it excels in CPU-intensive workloads. The 30 MB of L3 cache and support for ECC memory also make it suitable for professional workstations where data integrity is critical. The unlocked multiplier allows for overclocking, which is a feature absent on the AMD part.

The AMD Ryzen 7 260, despite losing all benchmarks, has a distinct role. Its 45 W TDP is the key differentiator: it is designed for mobile platforms (AMD Socket FP8) where power efficiency is paramount. The Radeon 780M integrated graphics are more capable for light gaming and media tasks than the UHD Graphics 770, and the higher memory bandwidth (89.6 GB/s) may benefit memory-bound applications that do not scale with core count. The 4 nm process node from TSMC means it generates far less heat and requires less cooling, making it suitable for thin-and-light laptops. For users who need a processor that runs on battery power and fits in a compact chassis, the Ryzen 7 260 is the only option between the two, given the Intel part's desktop-only Socket 1700.

There is no scenario in the recorded data where the Ryzen 7 260 outperforms the i9-12900K. The decision between them is therefore a choice between raw desktop performance (Intel) and mobile efficiency (AMD).
