AMD Ryzen 7 9850X3D vs Intel Core Ultra 5 225T Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the AMD Ryzen 7 9850X3D, which wins 13 of the 15 recorded head-to-head comparisons. The Intel Core Ultra 5 225T takes only 2 wins, and one of those is by a razor-thin margin.

The largest margins favor the AMD part in heavily threaded and data-focused workloads. In PassMark integer math, the Ryzen 7 9850X3D scores 123,140 against 59,543 for the Intel chip, a 106.8% advantage. Data compression shows a similar story: 474,501 versus 233,998, a 102.8% lead. PassMark physics also goes heavily to AMD at 4,171 versus 2,053, a 103.2% delta. Extended instructions follow the same pattern, with AMD at 39,272 and Intel at 20,083, a 95.5% difference.

Multithreaded rendering benchmarks reinforce the pattern but with a smaller gap. In Cinebench R15 multicore, the AMD processor scores 3,551 against 2,214, a 60.4% win. PassMark multithread shows 41,318 versus 25,358, a 62.9% delta. However, Cinebench R23 multicore narrows considerably: 22,807 versus 21,971, only a 3.8% margin for AMD. This suggests that while AMD dominates in many parallel workloads, the specific instruction mix and scaling behavior of Cinebench R23 closes much of the distance.

Random string sorting goes to AMD by 72.9%, with scores of 49,764 and 28,774. Prime number finding favors AMD at 435 versus 284, a 53.2% lead. Data encryption is a 25% advantage for AMD, 22,856 versus 18,289.

Single-threaded results are closer. Cinebench R15 single-core gives AMD 343 versus 312, a 9.9% win. PassMark single-thread shows 4,704 versus 4,348, an 8.2% advantage for AMD. The one clear Intel victory in the single-core column is Cinebench R23 single-core, where Intel scores 3,101 against AMD's 2,228, a 28.2% lead for Intel. This is the largest single delta in either direction across all tests.

The other Intel win is PassMark floating point math: 82,751 versus 81,998, a 0.9% margin. That is effectively a tie, but the recorded data lists Intel as the winner. Aside from those two results, the AMD processor leads every other benchmark, often by large margins.

Overall average benchmark scores place the Ryzen 7 9850X3D at 58,386, which sits at the 92nd percentile among all CPUs. The Core Ultra 5 225T averages 30,468, at the 82nd percentile. The nearest rivals for the AMD part include the Intel Xeon Platinum 8260M at 58,323 (0.1% behind) and the Intel Xeon w5-2545 at 58,504 (0.2% ahead). For the Intel chip, the closest competitors are the Intel Core i9-11980HK at 30,422 (0.2% behind) and the AMD Ryzen 5 7640HS at 30,390 (0.3% behind). These rival comparisons place both processors in their respective performance tiers, but the tiers themselves are far apart.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 7 9850X3D uses the Zen 5 architecture on the Granite Ridge codename, built on a 4 nm process at TSMC. The Intel Core Ultra 5 225T uses the Arrow Lake architecture, codename Arrow Lake-S, on a 3 nm process also at TSMC.

Core and thread counts differ significantly. AMD provides 8 cores and 16 threads, relying on simultaneous multithreading. Intel provides 10 cores and 10 threads, with no multithreading. Despite having two fewer cores, the AMD part's 16 threads give it a scheduling advantage in heavily threaded workloads, which shows in the benchmark results.

Cache layouts are also distinct. AMD allocates 80 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3 cache. Intel allocates 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3. The AMD L3 is 4.8 times larger, which explains its strong showing in data compression and integer math, where large working sets fit in cache. Intel's larger per-core L1 and L2 do not compensate in the recorded tests.

Clock speeds favor AMD in base frequency: 4.70 GHz versus 2.50 GHz for Intel. Boost clocks are closer, with AMD at 5.60 GHz and Intel at 4.90 GHz. Power envelopes differ substantially: the AMD part has a TDP of 120 watts, while the Intel part is rated at 65 watts. The Intel chip is locked (multiplierUnlocked is false), while AMD allows unlocked multipliers.

Both support DDR5 memory over a dual-channel bus. Memory bandwidth numbers differ slightly: AMD is rated at 89.6 GB/s, Intel at 102.4 GB/s. ECC memory support is present on AMD but not on Intel. PCIe connectivity also differs: AMD offers Gen 5 with 24 lanes (CPU only), while Intel offers Gen 5 with 20 lanes (CPU only).

Transistor counts and die sizes show the manufacturing differences. The AMD chip contains 8,315 million transistors on a 70.6 mm² die. The Intel chip contains 17,800 million transistors on a 243 mm² die. Despite the larger transistor count, the Intel part does not translate that into benchmark wins.

Integrated graphics differ as well. AMD includes Radeon Graphics. Intel includes Arc Xe-LPG Graphics 16EU. The release dates are also different: AMD launched on 2026-01-28, while Intel launched earlier on 2024-12-31. Both are listed as Active in production status and target the Desktop market segment. AMD's launch MSRP is $499; the Intel part has no recorded launch MSRP.

The Verdict

The recorded data points to the AMD Ryzen 7 9850X3D as the stronger processor in almost every measured category. With 13 wins out of 15 head-to-head comparisons, an average benchmark score of 58,386, and a 92nd percentile ranking, it sits well above the Intel Core Ultra 5 225T, which averages 30,468 and ranks at the 82nd percentile.

The AMD part is the choice for workloads that use many threads, large caches, or heavy integer and data operations. Its 96 MB L3 cache and 16 threads produce leads of over 100% in integer math and physics, and over 100% in data compression. For rendering tasks measured by Cinebench R23 multicore, the lead narrows to 3.8%, so the advantage is smaller but still present.

The Intel Core Ultra 5 225T has specific strengths. Its Cinebench R23 single-core score of 3,101 beats AMD by 28.2%, making it the better option for lightly threaded tasks that rely on that specific benchmark. Its floating point math result is also marginally ahead, by 0.9%. With a 65 watt TDP and a locked multiplier, it is positioned as a lower-power, efficiency-oriented desktop part.

Users who prioritize multi-threaded throughput, large cache-sensitive workloads, or raw parallel compute should select the AMD processor based on the data. Users who need the fastest recorded single-core result in Cinebench R23 or who operate under a strict power envelope may prefer the Intel part. The benchmark data does not support a broader recommendation for Intel beyond those two specific wins.

Where Each One Wins

The AMD Ryzen 7 9850X3D wins in multi-threaded rendering, as shown by Cinebench R15 multicore (60.4% lead) and Cinebench R23 multicore (3.8% lead). It also wins in all recorded PassMark CPU tests except floating point math. The largest wins come in integer math (106.8%), physics (103.2%), data compression (102.8%), extended instructions (95.5%), and random string sorting (72.9%). It also leads in multithread (62.9%), prime number finding (53.2%), data encryption (25%), Cinebench R15 single-core (9.9%), and PassMark single-thread (8.2%). Its 96 MB L3 cache and 16 threads drive these results.

The Intel Core Ultra 5 225T wins in Cinebench R23 single-core by a substantial 28.2%, indicating an advantage in that specific single-threaded rendering workload.
