AMD FX-8350 vs Intel Core i7-970 Comparison

The AMD FX-8350 and Intel Core i7-970 occupy an unusual position in the database: two end-of-life desktop processors from the early 2010s that land on the same rung of the historical performance ladder, with average benchmark scores of 1557 and 1613 respectively, and both sitting at the 39th percentile against all recorded CPUs. Despite that near-parity in aggregate terms, the two chips get there through completely different hardware philosophies, and the recorded data makes the contrast easy to read. The FX-8350 is an eight-core, high-clock Piledriver part on AMD's Socket AM3+, while the i7-970 is a six-core, twelve-thread Westmere design on Intel's Socket 1366 with a much larger shared L3 cache and a triple-channel memory controller.

Head-to-Head Benchmarks

A direct head-to-head comparison of these two parts is complicated by one important gap in the database: there are no overlapping benchmark results recorded for both chips. The FX-8350's entry carries Geekbench results only, while the Core i7-970's entry carries Cinebench R15, R20, and R23 results only. That means the two cannot be compared on a shared test, and any cross-family reading of the raw scores would be methodologically invalid, since Geekbench and Cinebench normalize on different scales.

What the database does support is a comparison through aggregate and percentile fields. The FX-8350 records an average benchmark score of 1557, and the i7-970 records 1613, a difference of 56 points, or roughly 3.6 percent in favor of the Intel part. Both processors sit at the 39th percentile versus all CPUs in the database, meaning that across the full measured population they occupy an effectively identical position. A gap of under four percent in average score, combined with identical percentile placement, is best described as a statistical tie in aggregate throughput.

The per-chip results that do exist can still be examined for what they say about each processor in isolation. The FX-8350 posts a Geekbench multi-core score of 2551 against a single-core score of 563. That is a multi-core to single-core ratio of roughly 4.5x, which reflects the eight-core configuration even though Piledriver's shared-module design means those cores do not scale as eight fully independent integer units. The i7-970's Cinebench R23 numbers show a multi-core score of 5577 against a single-core score of 787, a ratio of roughly 7.1x, which is an unusually strong scaling figure for a six-core, twelve-thread processor and points to Hyper-Threading doing real work in threaded rendering loads. In Cinebench R20 the i7-970 scores 2342 multi-core and 330 single-core, and in R15 it scores 562 multi-core and 79 single-core, a consistent scaling profile across three generations of the same test.

The rival context recorded alongside each part reinforces the tie reading. The FX-8350's nearest neighbors include the Intel Xeon E3-1268L v5 at an average score of 1557, the Intel Core i3-1115G4E at 1559, the AMD Opteron 6276 at 1560, and the Intel Core i3-9300 at 1554, all within a fraction of a percent. The i7-970's neighbors are the Intel Core i7-10610U at 1611, the Intel Xeon E3-1240L v5 at 1609, the Intel Core i3-9100T at 1620, and the Intel Core i3-9100E at 1605. In other words, both chips rank alongside modern low-power mobile and desktop parts in the database's aggregate scoring, and the small difference between them is comparable to the spread within each chip's own rival cluster.

Where Each One Wins

Because there are no shared benchmark results, wins must be assigned on architectural and configurational evidence rather than direct test scores.

The FX-8350's case rests on its higher clock speeds and unlocked multiplier. It runs at a 4.00 GHz base clock and boosts to 4.20 GHz, against the i7-970's 3.20 GHz base and 3.47 GHz boost. With its multiplier unlocked, the FX-8350 is the only one of the two that supports multiplier-based overclocking, which matters for users who want to extract more from threaded workloads on the AM3+ platform. Its eight physical cores also give it a natural fit for software that spawns many parallel threads and does not depend on per-thread speed. The recorded memory bandwidth of 29.9 GB/s over a dual-channel DDR3 controller quantifies its memory subsystem for anyone building around it.

The i7-970's case rests on threading efficiency and cache. Its twelve threads on six cores produced that 7.1x multi-core to single-core scaling ratio in Cinebench R23, indicating that SMT is delivering substantial gains in rendering-class workloads. Its 12 MB shared L3 cache is half again the size of the FX-8350's 8 MB shared L3, and its per-core L2 of 256 KB with 64 KB of L1 per core gives each core a private, fast cache hierarchy, in contrast to the FX-8350's shared-module design. The triple-channel DDR3 memory controller is also a platform advantage, since the FX-8350 is limited to dual-channel, and the i7-970's base architecture was designed around feeding six cores through that wider pipe.

Neither chip has integrated graphics worth factoring in as a win: the i7-970 has none at all, and the FX-8350's graphics support exists only as a chipset feature on certain motherboards, not on the processor die itself.

The Verdict

For a buyer choosing between these two on the recorded data, the decision is close on aggregate performance but clear on the margins. The i7-970 posts the higher average score, 1613 versus 1557, and shows stronger threaded scaling in its recorded Cinebench results, making it the better fit for rendering and heavily threaded productivity work, provided the Socket 1366 platform and its triple-channel memory are acceptable. The FX-8350 counters with a 56-point lower average score that is, in context, within the noise of its own rival cluster, higher stock clocks, an unlocked multiplier for overclocking, and eight physical cores at a launch MSRP of $199. Users who prioritize tunability and per-thread clock speed should lean FX-8350; users who prioritize cache size, memory channel width, and measured threaded scaling should lean i7-970. Both are end-of-life parts sitting at the same 39th percentile, so neither represents a performance tier above the other in the database's view.

FAQ

A: The Core i7-970, at 1613 versus 1557 for the FX-8350, a difference of 56 points, or about 3.6 percent.

Q: How do the two compare against all CPUs in the database?

A: They are identical in percentile terms. Both sit at the 39th percentile versus all recorded CPUs.

Q: Which chip can be overclocked by multiplier?

A: The FX-8350. Its multiplier is unlocked. The i7-970's multiplier is locked.

Q: What are the clock speeds of each processor?

A: The FX-8350 has a 4.00 GHz base clock and a 4.20 GHz boost clock. The i7-970 has a 3.20 GHz base clock and a 3.47 GHz boost clock.

Q: Which processor has the larger cache and wider memory support?

A: The i7-970, with 12 MB of shared L3 cache and a triple-channel DDR3 memory bus. The FX-8350 has 8 MB of shared L3 and a dual-channel DDR3 bus, though the database records its memory bandwidth at 29.9 GB/s.

Architecture Differences

Both processors were built on 32 nm process technology, but by different foundries: the FX-8350's Vishera die was fabbed by GlobalFoundries, while the i7-970's Gulftown die was fabbed by Intel. The transistor counts are close, 1,200 million for the FX-8350 against 1,170 million for the i7-970, but the die sizes diverge significantly. The FX-8350's die measures 315 mm² against the i7-970's 239 mm², so AMD spent substantially more silicon area for its eight-core Piledriver layout.

The core and thread structures differ fundamentally. The FX-8350 exposes 8 cores and 8 threads on the Piledriver architecture, arranged in AMD's module design with shared resources, and pairs them with 8 MB of L2 and 8 MB of shared L3, plus 384 KB of L1. The i7-970 exposes 6 cores and 12 threads on Westmere using Hyper-Threading, with a private per-core cache hierarchy of 64 KB L1 and 256 KB L2 per core, and 12 MB of shared L3. The i7-970's larger L3 and per-core private caches contrast with the FX-8350's approach of more cores with shared L2 modules.

Platform features are largely parallel. Both support DDR3 memory, both offer PCIe Gen 2, and neither supports ECC. The sockets differ completely: AMD Socket AM3+ for the FX-8350, Intel Socket 1366 for the i7-970, so the two are not cross-buildable. TDP is nearly identical at 125 W for the FX-8350 and 130 W for the i7-970. Release timing favors AMD's part as the newer design, launching on October 23, 2012 against July 19, 2010 for the i7-970, and the FX-8350 is the only one of the two with a recorded launch MSRP, at $199. Both are now end-of-life, and both were marketed in the desktop segment.
