The AMD Phenom II X6 1035T sits at 881, exactly matching the Athlon Silver 7120U and the Intel Core i3-1000NG4.

Architecture Differences

The Intel Core i7-930 is built on the Nehalem architecture with the Bloomfield codename, fabricated by Intel on a 45 nm process using 731 million transistors across a 263 mm² die. In contrast, the AMD Phenom II X6 1035T uses the K10 architecture with the Thuban codename, produced by GlobalFoundries on a 45 nm process but with a larger 904 million transistors and a 346 mm² die. The transistor count difference is notable — AMD packs 23% more transistors into a 31% larger die, yet achieves nearly identical performance.

The cache hierarchies diverge significantly. The Intel chip features 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 8 MB of shared L3 cache. The AMD chip offers double the L1 cache at 128 KB per core, double the L2 cache at 512 KB per core, but only 6 MB of shared L3 cache. This means the AMD design relies more heavily on per-core private cache, while Intel's larger shared L3 pool benefits its multi-threaded approach.

Memory controllers also differ fundamentally. The Intel Core i7-930 uses a triple-channel DDR3 memory bus, while the AMD Phenom II X6 1035T uses a dual-channel bus that supports both DDR2 and DDR3, with a specified memory bandwidth of 21.3 GB/s. The AMD chip also includes ECC memory support, a feature absent from the Intel part. Both processors use PCIe Gen 2, but the AMD chip lists "On certain motherboards (Chipset feature)" for integrated graphics, whereas the Intel chip has none. The Intel part uses Socket 1366, while the AMD uses Socket AM3, ensuring no platform compatibility between them.

Where Each One Wins

The data presents an unusual scenario where the Intel Core i7-930 officially wins all five head-to-head benchmarks, yet the margins are so razor-thin that the practical winner depends entirely on workload nuances not captured in these Cinebench tests. The Intel chip edges ahead in multi-core tests by 0.1%, suggesting its 8 threads provide a marginal advantage in heavily threaded rendering scenarios, even with two fewer physical cores.

The AMD Phenom II X6 1035T, despite losing every benchmark, offers structural advantages that translate to different use cases. Its 6 physical cores and larger private L1/L2 caches could theoretically benefit workloads with high per-thread cache locality, though the Cinebench data shows no measurable difference. The AMD chip's lower 95-watt TDP makes it the clear choice for power-constrained builds, and its ECC memory support positions it for error-sensitive environments like basic servers or workstations.

The identical single-core scores (151 in R20, 361 in R23) indicate that for lightly threaded applications — legacy software, everyday productivity, or older games — neither processor has any edge. The tie extends to Cinebench R15 multi-core at exactly 258 points each, meaning the Intel's 0.1% wins in newer Cinebench versions are the only differentiators. The AMD's dual-channel memory support for DDR2 could appeal to users upgrading an existing AM2+/AM3 platform without replacing memory, while the Intel's triple-channel design theoretically offers higher memory bandwidth, though no bandwidth benchmark is provided.

Specification Differences

The two processors differ across nearly every core specification field. The Intel Core i7-930 offers 4 cores and 8 threads, while the AMD Phenom II X6 1035T offers 6 cores and 6 threads — a reversal of the core/thread ratio. Base clocks are 2.80 GHz for Intel versus 2.60 GHz for AMD, but boost clocks reverse this: 3.07 GHz for Intel versus 3.10 GHz for AMD. TDP favors AMD substantially at 95 watts versus 130 watts for Intel.

Cache configurations differ in every tier: Intel has 64 KB L1 per core, 256 KB L2 per core, and 8 MB shared L3; AMD has 128 KB L1 per core, 512 KB L2 per core, and 6 MB shared L3. Memory support differs, with Intel limited to DDR3 triple-channel and AMD supporting both DDR2 and DDR3 dual-channel, with AMD also offering ECC memory. The AMD chip carries a specified memory bandwidth of 21.3 GB/s, while Intel lists none. Socket platforms are incompatible: Intel Socket 1366 versus AMD Socket AM3. Transistor counts are 731 million (Intel) versus 904 million (AMD), and die sizes are 263 mm² versus 346 mm². Both use 45 nm process nodes, but Intel uses its own foundry while AMD uses GlobalFoundries. Neither processor has an unlocked multiplier, and both are end-of-life desktop parts. Release dates differ by roughly two months: Intel launched on February 27, 2010, and AMD on April 26, 2010.

Head-to-Head Benchmarks

The most striking result is the exact tie in Cinebench R15 multi-core, where both processors score 258 points. This is the only test where the deltaPct is listed as 0% but the winner is still designated as the Intel Core i7-930, suggesting a tie-break rule based on the slight edge seen elsewhere. The R20 multi-core test shows the Intel winning 1076 to 1075, a 0.1% margin that represents a single point — within any reasonable margin of error but recorded as a win.

Cinebench R20 single-core produces another exact tie at 151 points each, with a 0% delta and the Intel chip given the win. The R23 multi-core test repeats the 0.1% pattern: Intel scores 2563 versus AMD's 2561, again a 2-point difference. The final test, Cinebench R23 single-core, is a third exact tie at 361 points each. Across all five tests, the Intel Core i7-930 accumulates 5 wins to 0 for AMD, yet the total point differential across all tests is only 3 points (1076-1075, 2563-2561, with three exact ties). The average benchmark scores reflect this: 882 for Intel and 881 for AMD, a 0.1% gap that places them as the closest rivals in each other's nearestRivals lists, with the Intel chip listed as 0.1% ahead of AMD and AMD listed as -0.1% behind Intel.

The Verdict

The data paints a picture of two processors that are functionally interchangeable in raw Cinebench performance, with the Intel Core i7-930 holding a microscopic 0.1% aggregate advantage. Users prioritizing multi-threaded rendering in applications like Cinebench should pick the Intel chip based on its 5-0 win record, but the margins are so small that real-world differences would be imperceptible. The Intel's 8 threads versus 6 physical cores appears to offset AMD's two additional cores, resulting in a draw that the benchmark software resolves in Intel's favor.

The AMD Phenom II X6 1035T becomes the rational choice for different reasons entirely. Its 95-watt TDP versus 130 watts for Intel makes it superior for thermally constrained builds or systems where power draw matters. ECC memory support is a decisive feature for users running memory-critical workloads, and the dual-channel DDR2/DDR3 compatibility offers upgrade flexibility for existing AM3 platforms. The larger L1 and L2 caches per core (128 KB and 512 KB versus 64 KB and 256 KB) suggest potential advantages in cache-sensitive workloads, though no benchmark data confirms this. The AMD chip also has a slightly higher boost clock (3.10 GHz versus 3.07 GHz), a minor edge for single-threaded burst activity.

For a new build where raw Cinebench scores are the sole criterion, the Intel Core i7-930 wins on paper by the slimmest possible margin. For an upgrade path or a system prioritizing power efficiency and ECC support, the AMD Phenom II X6 1035T offers the same performance with meaningful platform advantages. The 23rd percentile ranking for both processors indicates they are firmly in the lower half of all CPUs, so neither should be chosen for demanding modern workloads. The data suggests these are legacy parts best suited for budget-conscious users with specific platform requirements, where the benchmark differences are effectively noise and the specification differences drive the decision.
