AMD Ryzen 7 7700X vs Intel Core i9-12900T Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split between the two processors depending on the workload type. The AMD Ryzen 7 7700X takes 13 of the 17 head-to-head comparisons, while the Intel Core i9-12900T wins 4. The most lopsided result appears in PassMark extended instructions, where the AMD part scores 32,033 against Intel's 20,054, a 59.7% advantage. That is the single largest delta in either direction.

The AMD processor also dominates in several other PassMark subtests. Data compression goes to AMD by 21.8% (420,240 vs. 345,021), and data encryption shows a 19.2% lead (24,732 vs. 20,750). Prime number finding favors AMD by 55.2% (180 vs. 116). Random string sorting is another AMD win at 25.2% (49,782 vs. 39,771). The multithread PassMark score lands at 35,686 for AMD versus 29,601 for Intel, a 20.6% margin. Integer math is closer, with AMD ahead by 4.1% (112,601 vs. 108,211). Single-thread PassMark also goes to AMD, 4,190 vs. 3,810, a 10% edge, and the duplicate singlethread entry confirms the same result.

The Intel part's wins are concentrated in Cinebench and one PassMark category. Cinebench R23 multicore goes to Intel by 22.2% (24,528 vs. 19,088), which is its largest margin of victory. Cinebench R23 singlecore shows an even bigger percentage gap of 42.6% in Intel's favor (3,462 vs. 1,987), though the absolute difference is smaller. Cinebench R15 singlecore also favors Intel, at 348 vs. 315, a 9.5% lead. The remaining Intel win is PassMark floating point math, 75,741 vs. 68,986, an 8.9% advantage.

Several benchmarks show AMD ahead with more moderate margins. Geekbench multicore favors AMD by 7.2% (12,451 vs. 11,615), while Geekbench singlecore is nearly even at 1.3% (2,289 vs. 2,259). Cinebench R15 multicore goes to AMD by 26% (3,113.5 vs. 2,472), and PassMark physics is an AMD win by 10.8% (2,007 vs. 1,811). In total, the AMD chip records 13 wins against 4 for Intel, but the Intel victories in Cinebench R23 and singlecore tests are substantial enough to matter for certain applications.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 7700X uses the Zen 4 architecture on the Raphael codename, built on a 5 nm process at TSMC. It has 8 cores and 16 threads. The Intel Core i9-12900T uses Alder Lake, specifically Alder Lake-S, on a 10 nm process at Intel. It packs 16 cores and 24 threads, which explains its multicore advantage in some workloads.

Cache layouts differ significantly. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. Intel provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 30 MB of shared L3. The total L3 is not listed for either, but the per-core and shared figures show Intel's larger per-core caches versus AMD's larger shared pool.

Memory support diverges sharply. The AMD chip supports only DDR5 with dual-channel memory and a listed bandwidth of 83.2 GB/s. The Intel chip supports both DDR4 and DDR5, also dual-channel, but no memory bandwidth figure is recorded. ECC memory is supported on AMD but not on Intel. PCIe lanes also differ: AMD offers Gen 5 with 24 CPU lanes, while Intel offers Gen 5 with 20 CPU lanes.

Integrated graphics are present on both. AMD includes Radeon Graphics, while Intel includes UHD Graphics 770. The AMD chip has a base clock of 4.50 GHz and boost clock of 5.40 GHz, while the Intel chip has a base clock of 1400.00 MHz (1.40 GHz) and boost clock of 4.90 GHz. The Intel part's very low base clock is consistent with its 35 W TDP, versus 105 W for AMD. Both have unlocked multipliers.

Die size and transistor counts also differ. AMD reports 6,570 million transistors on a 71 mm² die. Intel reports no transistor count but a 215 mm² die. The process node difference (5 nm vs. 10 nm) explains why AMD fits more transistors on a smaller die. Release dates are close, with Intel launching on 2022-01-03 and AMD on 2022-09-26. Both parts remain in active production.

The Verdict

The data suggests two different usage profiles. The AMD Ryzen 7 7700X is the stronger all-around performer, winning 13 of 17 head-to-head tests and showing particularly large margins in extended instructions (59.7%), prime number finding (55.2%), Cinebench R15 multicore (26%), and random string sorting (25.2%). Its Geekbench multicore lead of 7.2% and PassMark multithread lead of 20.6% reinforce the picture of a chip that handles diverse threaded workloads with ease. For users running data compression, encryption, integer math, or physics simulations, the AMD part is clearly ahead.

The Intel Core i9-12900T is the choice for specific scenarios. Its 22.2% lead in Cinebench R23 multicore and 42.6% lead in Cinebench R23 singlecore indicate a strong showing in rendering tasks that scale with core count and in lightly threaded Cinebench workloads. The 9.5% win in Cinebench R15 singlecore and 8.9% win in PassMark floating point math add to its niche appeal. With 16 cores and 24 threads versus AMD's 8 cores and 16 threads, the Intel part has a raw core advantage that shows up in Cinebench R23 multicore, but that advantage does not translate to most other benchmarks in the dataset.

The 35 W TDP of the Intel part versus 105 W for AMD is a notable differentiator, though the performance data does not include power efficiency metrics. The AMD chip's higher boost clock (5.40 GHz vs. 4.90 GHz) and smaller process node (5 nm vs. 10 nm) likely contribute to its wins in latency-sensitive tests. The Intel part's support for both DDR4 and DDR5 gives it more memory flexibility, while AMD's exclusive DDR5 support aligns with its higher listed bandwidth of 83.2 GB/s. ECC memory support on AMD is a differentiator for data-integrity-focused builds.

Both processors sit at the 85th percentile among all CPUs, and their average benchmark scores are close: 35,909 for AMD versus 37,112 for Intel. The Intel part's nearest rival is the AMD Ryzen 7 160 at a 0% delta, while AMD's nearest rival is the AMD Ryzen 7 PRO 5845 at 0.3% ahead. This indicates the two CPUs are in the same performance tier overall, but the distribution of wins favors AMD in breadth and Intel in specific rendering workloads. Users who prioritize Cinebench-style rendering should look at the Intel chip. Users who want consistent wins across compression, encryption, math, and general multithreaded tasks should choose the AMD Ryzen 7 7700X.
