Q: Which CPU wins more head-to-head benchmark comparisons?

A: The AMD Ryzen 7 9800X3D wins 12 of the 15 recorded head-to-head tests. The Intel Core Ultra 3 205 wins only 3, which include Cinebench R23 single-core, PassMark single-thread, and PassMark single-thread (duplicate entry).

Q: What is the single-thread performance difference between the two?

A: In PassMark single-thread, the Intel Core Ultra 3 205 scores 4,575 versus 4,430 for the AMD Ryzen 7 9800X3D, a 3.2% lead for Intel. However, in Cinebench R23 single-core, Intel wins by a larger margin: 2,803 versus 2,080, which is a 25.8% advantage for Intel. In Cinebench R15 single-core, AMD leads with 328 versus 282, a 16.3% difference.

Q: How do the multi-core results compare?

A: The AMD Ryzen 7 9800X3D dominates multi-core workloads. In Cinebench R23 multi-core, AMD scores 23,230 versus 19,856 for Intel, a 17% lead. In Cinebench R15 multi-core, AMD scores 3,647 versus 2,001, an 82.3% advantage. PassMark multithread shows 40,009 for AMD versus 26,167 for Intel, a 52.9% difference.

Q: What are the core and thread counts for each processor?

A: Both CPUs have 8 cores. The AMD Ryzen 7 9800X3D supports 16 threads, while the Intel Core Ultra 3 205 supports 8 threads. This means the AMD chip has simultaneous multithreading enabled, while the Intel chip does not.

Q: What is the TDP difference between the two?

A: The AMD Ryzen 7 9800X3D has a TDP of 120 watts, while the Intel Core Ultra 3 205 has a TDP of 57 watts. The Intel part draws less than half the power budget of the AMD part, which may be relevant for system cooling and power supply requirements.

The Verdict

The data points to a clear split between the two processors based on workload type. The AMD Ryzen 7 9800X3D is the stronger choice for multi-threaded and compute-heavy tasks. Its 82.3% lead in Cinebench R15 multi-core, 17% lead in Cinebench R23 multi-core, and 113.1% lead in PassMark integer math make it the superior option for rendering, compilation, or any workload that scales with thread count. The 16 threads versus 8 threads is a structural advantage that shows up consistently across every multi-threaded benchmark in the database.

The Intel Core Ultra 3 205, despite having fewer threads, wins in specific single-thread scenarios. Its 25.8% advantage in Cinebench R23 single-core and 3.2% lead in PassMark single-thread indicate that for lightly threaded applications, particularly those that depend on a single core's peak performance, Intel has the edge. However, the AMD chip still wins Cinebench R15 single-core by 16.3%, so the single-thread picture is not uniform.

For buyers who prioritize multi-core throughput, the Ryzen 7 9800X3D is the obvious selection. For those who run mostly single-threaded software and want lower power draw, the Intel Core Ultra 3 205 offers a compelling alternative, especially given its 57-watt TDP versus 120 watts. The Intel part also uses a different socket (Intel Socket 1851 versus AMD Socket AM5), so platform choice will factor into any decision. The AMD part has an unlocked multiplier, while the Intel part is locked, which matters for overclocking-oriented users.

Head-to-Head Benchmarks

The largest victory for the AMD Ryzen 7 9800X3D comes in PassMark integer math, where it scores 116,709 versus 54,755 for Intel, a 113.1% advantage. This is more than double the Intel score and reflects the AMD chip's superior per-core integer throughput combined with double the thread count. PassMark physics also shows a massive gap: 4,083 for AMD versus 2,016 for Intel, a 102.5% difference.

Cinebench R15 multi-core delivers an 82.3% win for AMD, with scores of 3,647 versus 2,001. This is the largest percentage margin in any Cinebench test. PassMark data compression follows closely with AMD scoring 468,017 versus 260,651, a 79.6% lead. PassMark extended instructions shows 38,808 for AMD versus 22,578 for Intel, a 71.9% difference.

PassMark find prime numbers gives AMD a 57.8% win (423 versus 268), and PassMark random string sorting shows a 56.1% lead for AMD (48,526 versus 31,083). PassMark multithread delivers 40,009 for AMD versus 26,167 for Intel, a 52.9% advantage. PassMark data encryption shows an 18% lead for AMD (22,158 versus 18,772), and PassMark floating point math is closer: 79,456 versus 75,136, a 5.7% edge for AMD.

The Intel Core Ultra 3 205 wins Cinebench R23 single-core by a substantial 25.8% margin, scoring 2,803 versus 2,080. This is the single largest win for Intel in the dataset. PassMark single-thread shows a narrower victory: 4,575 versus 4,430, a 3.2% lead. The duplicate PassMark single-thread test confirms the same result. Intel also wins no other tests in the head-to-head comparison.

The pattern is unmistakable: AMD dominates in multi-threaded and math-intensive workloads, while Intel takes the top spot in one specific single-core test and edges out AMD in another. The 12-to-3 win count in favor of AMD reflects this overall trend.

Specification Differences

The two processors differ in several key specifications. The AMD Ryzen 7 9800X3D has a base clock of 4.70 GHz and a boost clock of 5.20 GHz. The Intel Core Ultra 3 205 runs at 3.80 GHz base and 4.90 GHz boost. AMD operates on the AM5 socket, while Intel uses Socket 1851.

Thread counts differ: AMD provides 16 threads from 8 cores, while Intel provides 8 threads from 8 cores. The TDP is 120 watts for AMD versus 57 watts for Intel. Memory bandwidth favors Intel: 102.4 GB/s versus 89.6 GB/s, though both support DDR5 and dual-channel memory. AMD supports ECC memory, Intel does not.

PCIe lane allocation differs: AMD offers Gen 5 with 24 lanes (CPU only), while Intel offers Gen 5 with 20 lanes (CPU only). The integrated graphics are different: AMD includes Radeon Graphics, while Intel includes Arc Xe-LPG Graphics 16EU. The AMD part has an unlocked multiplier, the Intel part does not. The release dates are also distinct: AMD launched on 2024-11-06, while Intel launched on 2025-07-31. The launch MSRP for AMD is $479, and for Intel it is $140.

Architecture Differences

The AMD Ryzen 7 9800X3D is built on Zen 5 architecture with the Granite Ridge codename, manufactured on a 4 nm process by TSMC. It integrates 8,315 million transistors on a 70.6 mm² die. The cache layout includes 80 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3 cache.

The Intel Core Ultra 3 205 uses Arrow Lake architecture with the Arrow Lake-S codename, manufactured on a 3 nm process by TSMC. It contains 17,800 million transistors on a 243 mm² die. The cache structure provides 192 KB of L1 per core, 3 MB of L2 per core, and 15 MB of shared L3 cache.

The transistor count difference is substantial: Intel packs more than double the transistors (17,800 million versus 8,315 million) on a die that is over three times larger (243 mm² versus 70.6 mm²). The 3 nm process node for Intel is smaller than AMD's 4 nm node, though both use TSMC as the foundry.

The L3 cache difference is notable: AMD's 96 MB shared L3 cache is six times larger than Intel's 15 MB. This large L3 cache is a hallmark of the 3D V-Cache design and contributes to AMD's strong performance in cache-sensitive workloads. Intel compensates with larger per-core L1 and L2 caches, but the shared L3 is significantly smaller. The architecture differences also extend to feature support, with AMD offering ECC memory and an unlocked multiplier, while Intel does not.
