AMD Ryzen 7 PRO 5755G vs Intel Core Ultra 9 285T Comparison

The Intel Core Ultra 9 285T and the AMD Ryzen 7 PRO 5755G occupy unusual positions in the desktop CPU landscape: both are efficiency-focused parts that still land in the 90th percentile of all processors in the database, yet they represent completely different eras and philosophies. The recorded data shows a clean sweep for Intel across every head-to-head benchmark, with margins ranging from modest to overwhelming, while AMD counters with a lower thermal envelope in practice-friendly terms, a different platform, and a much smaller die. What follows is a step-by-step walkthrough of where each chip wins, why, and what that means for a buyer.

Where Each One Wins

The headline is blunt: the Core Ultra 9 285T wins all eleven recorded head-to-head tests, and the Ryzen 7 PRO 5755G wins none. That alone settles the performance question, but the size of the gaps varies enormously by workload, and that variation tells the real story.

In lightly threaded responsiveness, the 285T posts a PassMark single-thread score of 4576 against 3366 for the 5755G, a 35.9% lead. In Cinebench R23 the gap widens further: 4739 versus a single-core figure the 5755G does not even record in the database, meaning Intel's advantage in per-core rendering throughput cannot be directly quantified on that test but is clearly substantial given the PassMark delta.

In heavily threaded work, the differences become dramatic. PassMark physics favors Intel by 178.1%, floating point math by 171.6%, and find-prime-numbers by a staggering 494.8%. These are exactly the workloads where 24 cores and 24 threads overwhelm 8 cores and 16 threads. Encryption (64.8% for Intel), extended instructions (34.1%), integer math (46.7%), data compression (29.9%), string sorting (45.5%), and the overall multithread rating (67.4% for Intel) all follow the same pattern.

Where does the 5755G win? Not in raw performance, but in structural attributes. It has a much higher base clock (3.80 GHz versus 1.40 GHz), a smaller 180 mm² die versus 243 mm², fewer transistors (10,700 million versus 17,800 million), and the AM4 platform with DDR4 support, which matters for anyone standardizing on existing infrastructure rather than chasing peak throughput.

Architecture Differences

These chips come from opposite ends of the architectural spectrum. The 285T is Arrow Lake-S, built on TSMC's 3 nm process, carrying 17,800 million transistors on a 243 mm² die. It deploys 24 cores and 24 threads: cores without simultaneous multithreading, but in vast quantity. Cache is generous, with 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. Memory support is DDR5 over a dual-channel bus delivering 102.4 GB/s of bandwidth, ECC is supported, and PCIe connectivity runs at Gen 5 with 20 CPU lanes. The integrated GPU is Arc Xe-LPG Graphics with 64 EUs. The launch MSRP is $549.

The 5755G is Cezanne, a Zen 3 design on TSMC's 7 nm node, with 10,700 million transistors on a 180 mm² die. It pairs 8 cores with 16 threads via SMT. Per-core cache is smaller: 64 KB of L1 and 512 KB of L2 per core, with 16 MB of L3. Memory is DDR4 over dual-channel at 51.2 GB/s, exactly half the bandwidth of the Intel part. ECC is not supported, PCIe stops at Gen 3 with 16 CPU lanes, and graphics duties fall to the Radeon Vega 8.

Two design choices stand out. First, TDP: Intel rates the 285T at 35 watts despite its 24 cores, while AMD rates the 5755G at 65 watts for 8 cores. Intel achieves this by dropping the base clock to 1.40 GHz and letting boost reach 5.40 GHz; AMD holds a higher 3.80 GHz base with a 4.60 GHz ceiling. Second, threading philosophy: fewer, faster, SMT-enabled cores on AMD versus many threads without SMT on Intel. The benchmark data shows the many-core approach, even at low base clocks, dominates throughput work on this generation gap.

In the database context, the 285T's average benchmark score of 51310 sits between rivals like the Core i9-14900T (0.6% behind Intel's new part) and the Core i9-13900F (0.8% ahead of it). The 5755G's 49196 average places it within a fraction of a percent of the Ryzen 9 7900 (0.1% apart) and the Core i5-14600KF (0.4%), an interesting cohort for an 8-core part.

The Verdict

For anyone whose workload is measured in throughput, rendering, computation, encryption, compression, or physics simulation, the data points unambiguously to the Core Ultra 9 285T. It leads in every recorded test, by margins from 29.9% to 494.8%, while drawing a rated 35 watts against the 5755G's 65 watts, and it does all this from a percentile position of 91 versus 90. Its platform is also more forward-looking: DDR5 at double the memory bandwidth, PCIe Gen 5 lanes, ECC support, and a newer integrated GPU in the Arc Xe-LPG with 64 EUs.

The Ryzen 7 PRO 5755G makes sense in a narrower set of cases implied by the data: an existing AM4 and DDR4 installation, where its Socket AM4 compatibility and DDR4 support avoid platform replacement, or deployments that never touch the heavily threaded workloads where it loses by triple-digit percentages. Its higher 3.80 GHz base clock means it holds frequency without relying on boost behavior, and its smaller die and transistor count reflect a simpler, older design. Its single-thread score of 3366 is genuinely competitive in absolute terms, 90th percentile overall, just not against this particular opponent.

Neither chip has an unlocked multiplier, so tuning is off the table for both.

Head-to-Head Benchmarks

Walking through the recorded results, the pattern is consistent but the magnitudes deserve attention.

The closest contest is data compression: 384140 for Intel versus 295730 for AMD, a 29.9% win. Extended instructions follows at 34.1% (27477 versus 20487), then single-thread at 35.9% (4576 versus 3366), string sorting at 45.5% (47695 versus 32771), and integer math at 46.7% (132433 versus 90270).

Encryption separates sharply: 32061 versus 19450, 64.8% to Intel. The overall PassMark multithread rating lands at 39931 versus 23858, a 67.4% gap that closely tracks the raw thread-count disparity.

Then come the outliers. Floating point math goes to Intel 137923 to 50778, a 171.6% margin. Physics is nearly identical in scale: 2842 versus 1022, 178.1%. Both tests scale almost linearly with available threads and per-core throughput, and the 285T has triple the advantage in each dimension. The most extreme result is find-prime-numbers, where 345 against 58 yields a 494.8% gap, the largest differential in the dataset and a pure illustration of what 24 modern cores at high boost clocks do to an 8-core Zen 3 design in an embarrassingly parallel integer workload.

For additional context from Intel's side, the Cinebench results reinforce the picture: 3384 multi-core and 477 single-core in R15, 14100 and 1990 in R20, and 33573 and 4739 in R23.

The specification table mirrors the benchmark story: the 285T brings a newer node, a larger cache hierarchy, double the memory bandwidth, newer I/O, and three times the cores, all at a lower rated TDP. The 5755G's remaining distinctions, its higher base clock and its established AM4/DDR4 platform, are exactly the reasons it still holds a 90th-percentile position despite the clean sweep against it in the recorded results.
