AMD Ryzen 7 9800X3D vs Intel Core 9 273PTE Comparison

The AMD Ryzen 7 9800X3D and Intel Core 9 273PTE occupy different positions in the desktop processor landscape. The recorded benchmark data shows a clear overall winner, but the Intel part claims a specific single-core crown. This analysis breaks down where each processor excels, the architectural choices behind their performance, and the exact numbers that define their head-to-head results.

Where Each One Wins

The AMD Ryzen 7 9800X3D dominates the multi-threaded and compute-heavy workloads. Out of the 15 shared benchmark tests, it wins 14. Its most decisive victories come in integer-heavy and physics simulations. The passmark_find_prime_numbers test shows a 197.9% advantage, with the AMD scoring 423 against Intel's 142. Similarly, passmark_extended_instructions shows a 143.3% lead (38808 vs 15952). These results indicate the AMD architecture handles complex instruction streams and mathematical workloads with far greater efficiency.

The passmark_multithread score reinforces this pattern. The AMD delivers 40009 points compared to 24054 for Intel, a 66.3% gap. The cinebench_r15_multicore test shows the largest percentage margin in the entire comparison at 77%, with the AMD scoring 3647 versus 2060. This suggests that in heavily threaded production tasks, the AMD processor provides a substantial performance cushion.

The Intel Core 9 273PTE wins exactly one test: cinebench_r23_singlecore. It scores 2886 against AMD's 2080, a 27.9% advantage. This is a significant result for lightly threaded applications, but the AMD counters with a win in cinebench_r15_singlecore (328 vs 290, a 13.1% lead) and passmark_single_thread (4430 vs 3433, a 29% lead). The Intel single-core victory in the modern cinebench version does not translate into consistent wins across other single-threaded tests.

For memory-sensitive tasks, the AMD again leads. Passmark_data_compression shows an 80.9% advantage (468017 vs 258704), and passmark_random_string_sorting shows a 67.5% lead (48526 vs 28973). Data encryption also favors AMD by 55.5% (22158 vs 14253). The overall pattern indicates the AMD processor is the stronger choice for content creation, scientific computing, and any workload that scales across multiple cores.

Architecture Differences

The two processors use fundamentally different design approaches. The AMD Ryzen 7 9800X3D is built on Zen 5 architecture with the Granite Ridge codename, fabricated on a 4 nm process by TSMC. It integrates 8,315 million transistors on a 70.6 mm² die. The Intel Core 9 273PTE uses Bartlett Lake architecture and is fabricated on a 10 nm process by Intel itself. The database does not list transistor count or die size for the Intel part.

Core configuration differs significantly. The AMD uses 8 cores and 16 threads, while the Intel uses 12 cores and 24 threads. Despite having 50% more cores and threads, the Intel part loses in most multi-threaded tests. The clock speeds tell a partial story: AMD has a base clock of 4.70 GHz and boost of 5.20 GHz, while Intel has a much lower base of 1.40 GHz but a higher boost of 5.50 GHz. The thermal design power (TDP) reflects this: AMD is rated at 120 W, Intel at 45 W.

Cache hierarchy is another major differentiator. Both use 80 KB of L1 cache per core and 1 MB of L2 per core for AMD versus 2 MB per core for Intel. The shared L3 cache is where they diverge sharply: AMD provides 96 MB shared, while Intel provides 36 MB shared. This 60 MB difference in L3 capacity helps explain the AMD's strong showing in data compression and encryption workloads, as more data can reside closer to the cores.

Memory support differs as well. AMD supports only DDR5, while Intel supports both DDR4 and DDR5. Both use dual-channel memory buses with identical 89.6 GB/s bandwidth. Both support ECC memory. PCIe connectivity favors AMD with Gen 5 and 24 lanes (CPU only), versus Intel's Gen 5 and 16 lanes. The integrated graphics also differ: AMD includes Radeon Graphics, Intel includes UHD Graphics 730.

The platforms themselves are incompatible: AMD uses Socket AM5, Intel uses Socket 1700. The AMD multiplier is unlocked for overclocking, while the Intel multiplier is locked. The release dates show the AMD launched on 2024-11-06, while the Intel is dated 2026-03-08. The AMD carries launch MSRP of $479, the Intel $549.

Head-to-Head Benchmarks

The largest margin in the entire comparison belongs to passmark_find_prime_numbers. The AMD scores 423 against Intel's 142, a 197.9% advantage. This test measures raw integer iteration speed, and the AMD's Zen 5 architecture demonstrates exceptional efficiency in this workload.

Passmark_extended_instructions shows the second-largest gap. AMD scores 38808, Intel scores 15952, a 143.3% lead. This test evaluates SIMD and vector instruction throughput, where the AMD's wider execution resources become apparent.

The cinebench_r15_multicore test delivers the biggest percentage difference in rendering workloads. AMD leads 3647 to 2060, a 77% margin. In cinebench_r23_multicore, the gap narrows to 13.6% (23230 vs 20445), suggesting the newer test version scales differently across the two architectures.

Passmark_physics shows a 113% advantage for AMD (4083 vs 1917). This test simulates rigid body physics, a common component in game engines and scientific simulations. The AMD's large L3 cache likely reduces memory latency for these sequential calculations.

Data compression results favor AMD by 80.9% (468017 vs 258704). The 96 MB L3 cache allows more of the working set to remain on-chip. Data encryption shows a 55.5% lead (22158 vs 14253), and random string sorting shows a 67.5% advantage (48526 vs 28973).

Floating point math sees AMD ahead by 31% (79456 vs 60673), while integer math shows a 41.6% lead (116709 vs 82411). The passmark_multithread test confirms the overall trend with AMD at 40009 versus 24054, a 66.3% gap.

The single-core results are more nuanced. Passmark_single_thread shows AMD at 4430 versus 3433, a 29% advantage. Cinebench_r15_singlecore shows AMD at 328 versus 290, a 13.1% lead. But cinebench_r23_singlecore flips the result: Intel scores 2886, AMD scores 2080, giving Intel a 27.9% win. This is the only test the Intel wins, and it demonstrates that the Intel's higher 5.50 GHz boost clock can deliver strong single-thread performance in certain rendering workloads.

The average benchmark scores place the AMD at 39768 and the Intel at 31143. The AMD sits in the 87th percentile of all CPUs, the Intel in the 82nd. The AMD's nearest rival, the AMD Ryzen 7 7700, has an average score of 40081, a 0.8% difference. The Intel's closest competitor, the Intel Core i7-12650HX, scores 31290, a 0.5% gap. These figures confirm that both processors perform at similar overall levels to their immediate peers, but the AMD holds a clear cross-processor advantage in the direct comparison.
