The Verdict

The data separates these two clearly by workload type. The AMD EPYC 7303 is the pick for heavily threaded, memory-saturating server workloads: it wins every Cinebench multi-core test by a consistent 39.2% margin, and its 16 cores with 32 threads provide double the thread count of the Intel part. The EPYC also leads in PassMark integer math by 22.5% and data compression by 8.8%, reinforcing its strength in throughput-oriented tasks.

The Intel Core Ultra 5 235 is the choice for single-threaded and latency-sensitive desktop applications. Its PassMark single-thread score of 4,516 versus 1,460 for the EPYC is a 209.3% advantage, and it wins PassMark multi-thread by 32.4% despite having fewer threads. Intel also dominates in floating-point math (81.6% ahead), prime number finding (106.1% ahead), and physics simulation (43.4% ahead).

The average benchmark scores are nearly identical (46,062 vs 45,960), meaning the aggregate performance is a wash. However, the distribution of wins tells the real story: if your software scales across many cores and benefits from massive memory bandwidth, the EPYC 7303 is the clear winner. If you need fast response times, encryption throughput, or run lightly threaded applications, the Intel Core Ultra 5 235 is the better fit.

Head-to-Head Benchmarks

The most striking pattern in the head-to-head data is the EPYC 7303's uniform sweep of the Cinebench suite. Across R15, R20, and R23, in both single- and multi-core variants, the AMD processor wins by 39.1% to 39.2% every time. For example, Cinebench R23 multi-core shows the EPYC at 24,286 versus Intel's 14,769, a 39.2% gap. This consistency suggests a fundamental architectural advantage in sustained rendering workloads, likely tied to the EPYC's 16 cores and 32 threads.

The Intel Core Ultra 5 235 counters with a completely different set of strengths. Its PassMark single-thread score of 4,516 is more than triple the EPYC's 1,460, a 209.3% margin. This carries over to PassMark multi-thread, where Intel scores 37,816 against AMD's 28,572, a 32.4% win. The Intel part also shows a massive 106.1% lead in prime number finding (371 vs 180) and an 81.6% lead in floating-point math (117,951 vs 64,940).

Some tests split the difference. In data compression, the EPYC wins with 428,319 versus 390,711, an 8.8% margin. In integer math, the EPYC takes a 22.5% lead (113,422 vs 87,948). However, Intel wins data encryption by 16.4% (29,293 vs 25,167), extended instructions by 3.6% (32,752 vs 31,603), random string sorting by 15.9% (48,980 vs 42,259), and physics by 43.4% (2,570 vs 1,792).

The overall win tally is 9 for Intel and 8 for AMD, but the margins are not symmetric. AMD's wins are almost entirely confined to the Cinebench suite and two PassMark tests, while Intel's wins span a broader range of PassMark workloads. The single-thread differential is the largest any test shows, meaning Intel's advantage in that area is far more pronounced than AMD's multi-core edge.

Specification Differences

The core and thread counts diverge sharply. The Intel Core Ultra 5 235 has 14 cores and 14 threads, indicating no hyperthreading, while the AMD EPYC 7303 has 16 cores and 32 threads, doubling the thread count via simultaneous multithreading. This explains the EPYC's multi-core Cinebench wins despite its lower clock speeds.

Clock speeds favor Intel: the Ultra 5 235 runs at 3.40 GHz base and 5.00 GHz boost, versus 2.40 GHz base and 3.40 GHz boost for the EPYC 7303. The 1.6 GHz boost advantage for Intel underpins its single-thread dominance. Power draw is also asymmetric, with Intel rated at 65W TDP and AMD at 130W TDP.

Memory configurations differ fundamentally. Intel supports DDR5 on a dual-channel bus with 102.4 GB/s bandwidth, while AMD supports DDR4 on an eight-channel bus with 204.8 GB/s bandwidth. The EPYC also supports ECC memory; the Intel part does not. PCIe connectivity favors AMD heavily at 128 Gen 4 lanes versus Intel's 20 Gen 5 lanes.

The Intel part includes integrated Arc Xe-LPG Graphics with 24 execution units, while the EPYC 7303 has no integrated graphics. Sockets are incompatible: Intel Socket 1851 versus AMD Socket SP3. The launch MSRP for the Intel Core Ultra 5 235 is $257; the AMD EPYC 7303 launched at $604.

Architecture Differences

The Intel Core Ultra 5 235 is built on Arrow Lake-S architecture, part of the Core Ultra Series 2, fabricated on a 3 nm process at TSMC. It integrates 17,800 million transistors on a 243 mm² die. Cache is organized as 192 KB L1 per core, 3 MB L2 per core, and 24 MB shared L3.

The AMD EPYC 7303 uses Zen 3 architecture under the Milan codename, part of the EPYC 7003 series, on a 7 nm process also at TSMC. It contains 8,300 million transistors spread across two dies of 81 mm² each. Cache differs substantially: 64 KB L1 per core, 512 KB L2 per core, and 64 MB shared L3 — nearly triple the Intel part's L3 capacity.

The process node gap is significant: 3 nm versus 7 nm, which partially explains the Intel part's lower TDP (65W vs 130W) and higher clock speeds. However, the EPYC's larger L3 cache and eight-channel memory interface give it a bandwidth advantage that the Intel chip cannot match. The Intel part's integrated graphics is a key architectural feature absent from the EPYC, making it a more self-contained desktop solution.

Where Each One Wins

Choose the Intel Core Ultra 5 235 for desktop and single-threaded workloads. The PassMark single-thread score is 209.3% higher, making it the obvious pick for applications that rely on responsiveness, such as interactive software or lightly threaded games. It also wins PassMark multi-thread by 32.4%, so even some parallel workloads favor Intel. Data encryption, extended instructions, floating-point math, prime number finding, physics, and random string sorting all go to Intel. The integrated graphics provide display output without a discrete GPU, and the 65W TDP suits compact desktop builds. The 5.00 GHz boost clock and 3 nm process node are the core advantages here.

Choose the AMD EPYC 7303 for server, workstation, and memory-bound workloads. The EPYC wins all six Cinebench tests by 39.1% to 39.2%, indicating strong sustained multi-core rendering performance. It also leads data compression by 8.8% and integer math by 22.5%. The 32 threads, 64 MB L3 cache, and 204.8 GB/s eight-channel memory bandwidth make it the better fit for virtualization, database workloads, and any task that scales with core count and memory throughput. ECC memory support is a critical feature for data integrity in server environments. The 128 PCIe Gen 4 lanes allow extensive expansion, and the 130W TDP is reasonable given the performance envelope.

The average benchmark scores are separated by only 0.2%, so the aggregate performance is nearly identical. The decision hinges on whether your workload resembles the Cinebench pattern (AMD wins) or the PassMark pattern (Intel wins). For mixed usage, the Intel part's broad PassMark sweep and single-thread dominance make it the more versatile general-purpose choice, while the EPYC's consistent multi-core lead makes it the specialist for throughput-critical server tasks.
