Architecture Differences

The AMD Ryzen 9 9950X3D is built on AMD's Zen 5 architecture with the Granite Ridge codename. It uses a 4 nm process node from TSMC and contains 16,630 million transistors across a die size of 2x 70.6 mm². The Intel Core 5 223PE uses the Bartlett Lake codename on a 10 nm process node from Intel. Intel does not record a transistor count or die size for this part.

Cache layouts differ significantly. Both parts use 80 KB of L1 cache per core. The AMD processor has 1 MB of L2 per core, while Intel has 2 MB of L2 per core. The L3 cache is a major differentiator: AMD provides 128 MB of L3 cache, whereas Intel provides 24 MB of shared L3.

Memory support also separates the two. The AMD Ryzen 9 9950X3D supports only DDR5 memory, while the Intel Core 5 223PE supports both DDR4 and DDR5. Both use a dual-channel memory bus and share the same memory bandwidth figure of 89.6 GB/s. Both support ECC memory.

The AMD part has its multiplier unlocked, meaning it can be overclocked. The Intel part has a locked multiplier. Both have an integrated GPU: AMD uses Radeon Graphics, Intel uses UHD Graphics 730. The AMD processor uses AMD Socket AM5, while Intel uses Intel Socket 1700. The AMD part carries a 170 W TDP, and the Intel part carries a 65 W TDP.

The Verdict

The benchmark data splits cleanly by workload type. The AMD Ryzen 9 9950X3D wins 13 of the 15 recorded head-to-head comparisons, including every multi-threaded test. Its closest rivals in the database are the AMD Ryzen 7 PRO 9755 and AMD Ryzen 7 PRO 9755X3D, each with an average score within 0.1% of the 9950X3D. The Intel Core 5 223PE is clustered with the Intel Core 7 253PE at a 0.1% delta and the Intel Xeon 6357P at a -0.1% delta.

For heavily parallel workloads, the AMD part is the clear choice. Its 16 cores and 32 threads deliver massive leads in every multi-core benchmark, with deltas ranging from 58.8% to 285.5% over the Intel part. The 128 MB L3 cache and higher TDP support sustained throughput in rendering, encoding, and scientific computing.

The Intel Core 5 223PE wins exactly two tests: Cinebench R15 single-core and Cinebench R23 single-core. In R23 single-core, it leads by 39.5% over the AMD part. That makes it the better option for lightly threaded tasks where a single core matters most, such as legacy applications or specific simulation workloads. However, in PassMark single-thread testing, the AMD part wins by 12.3%, showing that Intel's single-core advantage is not universal across all benchmark suites.

A builder choosing between these two should base the decision on thread count requirements. If the workload scales beyond 8 cores, the AMD Ryzen 9 9950X3D dominates. If the workload is strictly single-threaded and cannot use additional cores, the Intel Core 5 223PE shows a measurable edge in two of the three single-thread tests recorded.

Head-to-Head Benchmarks

The largest margin comes in PassMark find prime numbers. The AMD Ryzen 9 9950X3D scores 613 versus 159 for the Intel Core 5 223PE, a delta of 285.5%. That is the single biggest relative win in the dataset.

PassMark extended instructions shows the AMD part at 73011 against 24672 for Intel, a 195.9% lead. This indicates a substantial advantage in workloads using advanced instruction sets.

Data compression favors AMD heavily. The 9950X3D scores 908421, while the 223PE scores 346623, a 162.1% delta. Random string sorting follows a similar pattern: 95423 versus 35798, a 166.6% lead for AMD.

Integer math and floating point math both go to AMD. Integer math shows 243209 versus 99819, a 143.7% delta. Floating point math shows 159724 versus 76468, a 108.9% delta.

Data encryption results show AMD at 44536 versus 18448 for Intel, a 141.4% delta. Physics simulation in PassMark gives AMD 5670 versus 2493, a 127.4% delta.

PassMark multithread shows AMD at 70255 versus 31124, a 125.7% delta. Cinebench R15 multicore shows AMD at 6536 versus 2666, a 145.2% delta. Cinebench R23 multicore shows AMD at 42018 versus 26455, a 58.8% delta.

The Intel wins are narrower in count but meaningful in single-core performance. Cinebench R23 single-core gives Intel 3734 versus 2259 for AMD, a -39.5% delta. Cinebench R15 single-core gives Intel 376 versus 350, a -6.9% delta.

The PassMark single-thread tests, which appear twice in the dataset, show AMD ahead: 4737 versus 4219, a 12.3% delta. This means the Intel single-core lead is suite-specific rather than consistent.

Where Each One Wins

The AMD Ryzen 9 9950X3D wins in every multi-threaded and throughput-oriented workload recorded. This includes Cinebench R15 and R23 multicore, PassMark multithread, integer math, floating point math, data compression, data encryption, extended instructions, prime number finding, physics simulation, and random string sorting. The 16-core, 32-thread configuration with 128 MB L3 cache drives these results. The 170 W TDP allows the part to sustain high output in long-running parallel tasks.

The AMD part also wins in PassMark single-thread testing by 12.3%. That gives it a broader single-thread footprint than the raw Cinebench numbers suggest. Its closest rivals are other high-core AMD parts, including the Ryzen 7 PRO 9755 and Ryzen 7 PRO 9755X3D, both within 0.1% average score. This positions the 9950X3D at the top of a tightly packed group of high-end desktop and workstation chips.

The Intel Core 5 223PE wins in Cinebench R15 single-core and Cinebench R23 single-core. The R23 result is particularly strong, with a 39.5% lead over the AMD part. This makes the Intel part suitable for software that depends on a single fast core, such as certain legacy CAD tools or older games that do not scale across cores. Its 65 W TDP also indicates lower power draw, which can simplify cooling in compact systems.

Intel's nearest rival group includes the Intel Core 7 253PE at a 0.1% delta and the Intel Xeon 6357P at a -0.1% delta. This shows the 223PE sits in a competitive mid-range tier, close to other Intel workstation parts. The 8-core, 16-thread configuration with 24 MB shared L3 is modest compared to the AMD part, but the single-core results prove it is not a weak processor.

In summary, the AMD Ryzen 9 9950X3D is the pick for multi-threaded compute, content creation, and any workload that can use 16 or more threads. The Intel Core 5 223PE is the pick for single-thread-bound applications where Cinebench-style performance matters and where the lower 65 W TDP and DDR4 compatibility are relevant. The recorded data shows 13 wins for AMD and 2 for Intel, but those two Intel wins are large enough to matter in specific use cases.
