AMD Ryzen 9 9900X vs Intel Core 9 273PTE Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a dominant performance profile for the AMD Ryzen 9 9900X. Out of 15 head-to-head comparisons, the AMD part claims 14 victories, while the Intel Core 9 273PTE manages a single win. The scale of those victories is substantial, with several deltas exceeding 100%.

The largest margin appears in the PassMark extended instructions test. The Ryzen 9 9900X scores 55,243 versus the Intel part's 15,952, a delta of 246.3%. This suggests a significant advantage in workloads that leverage specialized CPU instruction sets. Data compression follows a similar pattern: the AMD processor records 683,579 points against 258,704 for the Intel chip, a 164.2% delta. The data encryption test shows a 134.5% delta (33,421 versus 14,253), indicating a strong lead in cryptography-related tasks.

Multi-threaded productivity benchmarks confirm the pattern. In Cinebench R23 multi-core, the Ryzen 9 9900X scores 32,172, while the Core 9 273PTE scores 20,445, a 57.4% delta. The older Cinebench R15 multi-core test shows a wider gap: 5,008 versus 2,060, a delta of 143.1%. PassMark multi-thread results also favor AMD heavily, with 54,643 versus 24,054, a 127.2% delta. Integer math shows a 119.7% delta (181,056 versus 82,411), while floating-point math has a 97.9% delta (120,083 versus 60,673).

The AMD advantage extends to memory and string handling. Random string sorting shows a 148.6% delta (72,013 versus 28,973). Prime number finding, a classic CPU stress test, shows a 207% delta (436 versus 142). Even the PassMark physics test, which often favors different architectures, goes to AMD by 76.4% (3,381 versus 1,917).

Single-thread results are more mixed. The Ryzen 9 9900X leads in Cinebench R15 single-core by 21.7% (353 versus 290) and in PassMark single-thread by 36.1% (4,672 versus 3,433). However, the Intel Core 9 273PTE wins the Cinebench R23 single-core test, scoring 2,886 against the AMD's 2,253, a delta of -21.9% from the AMD perspective. This is the sole benchmark where the Intel part comes out ahead, and it is a notable outlier given the rest of the data.

Where Each One Wins

The data splits the two processors into very different use-case categories. The AMD Ryzen 9 9900X is the clear choice for any workload that scales with thread count, core count, or raw computational throughput. Its wins in Cinebench R23 multi-core, PassMark multi-thread, integer math, and floating-point math indicate strong performance in rendering, video encoding, scientific simulation, and general productivity suites. The extended instructions lead suggests the AMD part handles AVX or similar vectorized workloads more efficiently. The encryption and compression results point toward file archiving, database operations, and secure communications tasks.

The Intel Core 9 273PTE, based on the recorded data, wins only in the Cinebench R23 single-core test. This specific result indicates that for a narrow set of lightly threaded applications, such as certain legacy software or single-threaded game engines that rely on one core, the Intel part can deliver a higher peak score. However, the AMD part wins the other single-thread test (Cinebench R15 single-core) and the PassMark single-thread tests, so the Intel advantage is not consistent across all single-thread measurements. The Cinebench R23 single-core score of 2,886 stands alone as its sole victory.

The overall average benchmark score reinforces the split. The Ryzen 9 9900X has an average score of 57,498, placing it in the 92nd percentile of all CPUs. The Intel Core 9 273PTE has an average score of 31,143, placing it in the 82nd percentile. The nearest rivals for the AMD part are the AMD EPYC 9015 (delta -0.1%), the AMD EPYC 7313 (delta 0.2%), the Intel Core i9-14900 (delta -1.1%), and the Intel Xeon Platinum 8260M (delta -1.4%). The Intel part's nearest rivals are the Intel Core i7-12700F (delta 0.2%), the AMD Ryzen 9 8945HS (delta 0.2%), the Intel Core i7-13700TE (delta 0.4%), and the Intel Core i7-12650HX (delta -0.5%). This places the Intel part in a lower performance tier, roughly comparable to mid-range desktop and high-end mobile chips, while the AMD part competes with server-class and high-end desktop processors.

Architecture Differences

The two CPUs differ fundamentally in their underlying design. The AMD Ryzen 9 9900X uses the Zen 5 architecture, codenamed Granite Ridge, and is built on a 4 nm process by TSMC. It packs 16,630 million transistors across two chiplets, each with a die size of 70.6 mm². The Intel Core 9 273PTE uses the Bartlett Lake architecture, built on a 10 nm process by Intel, with no transistor count or die size data recorded.

Cache configurations diverge sharply. Both have 80 KB of L1 cache per core and 1 MB of L2 cache per core for AMD versus 2 MB of L2 cache per core for Intel. The L3 cache is the major difference: AMD offers 64 MB of L3, while Intel offers 36 MB shared. This larger L3 cache on the AMD part likely contributes to its strong performance in data compression and random string sorting, as more data can reside closer to the cores.

Clock speeds and power draw tell a different story. The AMD Ryzen 9 9900X has a base clock of 4.40 GHz and a boost clock of 5.60 GHz, with a TDP of 120 watts. The Intel Core 9 273PTE has a base clock of 1.40 GHz and a boost clock of 5.50 GHz, with a much lower TDP of 45 watts. The Intel part's low base clock and 45-watt TDP indicate a power-optimized design, likely intended for thermally constrained systems. Despite the lower power envelope, its boost clock is within 0.10 GHz of the AMD part.

Memory support also differs. Both support dual-channel memory with 89.6 GB/s bandwidth. However, the AMD part supports DDR5 only, while the Intel part supports both DDR4 and DDR5. Both support ECC memory. PCIe lanes differ: AMD provides 24 PCIe Gen 5 lanes (CPU only), while Intel provides 16 PCIe Gen 5 lanes (CPU only). The integrated graphics differ as well: AMD uses Radeon Graphics, while Intel uses UHD Graphics 730.

The sockets are incompatible. AMD uses Socket AM5, while Intel uses Socket 1700. The AMD part has an unlocked multiplier, while the Intel part does not. The AMD part launches with an MSRP of $499, and the Intel part with an MSRP of $549.

The Verdict

The benchmark data clearly favors the AMD Ryzen 9 9900X for almost every measurable workload. The 14-to-1 win count, combined with deltas that often exceed 100%, indicates a processor that is substantially faster in multi-threaded, data-intensive, and math-heavy tasks. The 92nd percentile placement, with an average score of 57,498, puts it in a performance class alongside server processors like the AMD EPYC 9015 and AMD EPYC 7313, as well as high-end desktop parts like the Intel Core i9-14900. For users who run rendering, compilation, data analysis, encryption, or any workload that uses multiple cores, the data says the AMD part is the stronger choice by a wide margin.

The Intel Core 9 273PTE has a single, narrow win in Cinebench R23 single-core. The 82nd percentile placement and average score of 31,143 place it near the Intel Core i7-12700F and AMD Ryzen 9 8945HS. This indicates a mid-range performer. The 45-watt TDP is the key differentiator: it delivers roughly half the average benchmark score of the AMD part while drawing significantly less power. The low base clock of 1.40 GHz suggests this is a processor designed for power efficiency rather than sustained all-core throughput. The support for both DDR4 and DDR5 memory also gives it flexibility for system builders with existing DDR4 platforms.

Strictly from the data, the AMD Ryzen 9 9900X is the pick for maximum performance. The Intel Core 9 273PTE is the pick for a low-power desktop chip that still offers a competitive single-core boost clock, but its multi-core performance lags the AMD part by margins that range from 57.4% to 246.3%. The choice depends on whether the workload prioritizes raw speed or power efficiency.
