AMD Athlon Silver 7120U vs Intel Core i7-930 Comparison

The Intel Core i7-930 and AMD Athlon Silver 7120U represent two distant eras of processor design, yet their average benchmark scores land nearly identically. The i7-930, a 2010 desktop flagship, averages 882 points, while the Athlon Silver 7120U, a 2022 mobile chip, averages 881 points—a negligible 0.1% difference. However, this parity in aggregate masks a fundamental split: the older Intel part dominates multi-threaded workloads, while the newer AMD chip crushes it in single-threaded performance. The data reveals two processors that solve the same problem in opposite ways, making the "winner" entirely dependent on the task at hand.

FAQ

Q: How do the average benchmark scores compare between the two CPUs?

A: The Intel Core i7-930 has an average benchmark score of 882, while the AMD Athlon Silver 7120U scores 881. The delta is a mere 0.1%, placing them statistically tied in overall performance, with both sitting at the 23rd percentile of all CPUs.

Q: Which processor wins in multi-core rendering workloads?

A: The Intel Core i7-930 wins decisively. In Cinebench R23 multi-core, it scores 2563 versus the Athlon's 1673, a 53.2% advantage. Its lead in Cinebench R15 multi-core is smaller but still present: 258 versus 250, a 3.2% margin.

Q: Which processor wins in single-core tasks?

A: The AMD Athlon Silver 7120U is the clear victor. In Cinebench R23 single-core, it scores 886 against the Intel's 361, representing a massive 59.3% deficit for the i7-930. The Athlon also posts 130 in Cinebench R15 single-core, a test the i7-930 does not have a recorded score for.

Q: What are the core and thread counts for each chip?

A: The Intel Core i7-930 has 4 cores and 8 threads, leveraging Hyper-Threading. The AMD Athlon Silver 7120U has 2 cores and 2 threads, with no simultaneous multi-threading support.

Q: What are the TDP ratings, and what does that imply about their target platforms?

A: The Intel Core i7-930 has a TDP of 130 watts, typical for a desktop part. The AMD Athlon Silver 7120U has a TDP of just 15 watts, indicating a low-power mobile design. This explains the i7-930's desktop Socket 1366 and the Athlon's mobile FT6 socket.

Q: Which processor has a more recent production status?

A: The AMD Athlon Silver 7120U is listed as "Active" production, released in September 2022. The Intel Core i7-930 is "End-of-life," having been released in February 2010.

Where Each One Wins

The benchmark data draws a clean line between these two processors. The Intel Core i7-930 is the multi-threaded workhorse. Its two wins in the head-to-head comparison come in Cinebench R15 and R23 multi-core tests. The architecture's 4 cores and 8 threads provide a raw throughput advantage that scales in heavily parallel workloads. For rendering, video encoding, or any task that can saturate multiple threads, the i7-930's 53.2% lead in Cinebench R23 multi-core makes it the superior choice.

Conversely, the AMD Athlon Silver 7120U wins the single-threaded crown. Its score of 886 in Cinebench R23 single-core is more than double the i7-930's 361. This advantage comes from the modern Zen 2 architecture and a higher boost clock of 3.50 GHz, compared to the Intel's 3.07 GHz. The Athlon is the better pick for everyday responsiveness, web browsing, and lightly-threaded applications where a single core's efficiency dictates performance. Its integrated Radeon 610M graphics also give it a functionality the i7-930 completely lacks, making it a more complete package for a basic mobile system.

Architecture Differences

These chips are separated by over a decade of silicon evolution. The Intel Core i7-930 is built on the 45 nm Nehalem architecture, codenamed Bloomfield, and fabricated by Intel. It contains 731 million transistors on a 263 mm² die. The AMD Athlon Silver 7120U uses the Zen 2 architecture, codenamed Mendocino, built on a 6 nm process by TSMC, with a much smaller 100 mm² die. This process shrink explains the massive efficiency gap: the Intel part draws 130 watts while the AMD chip consumes just 15 watts.

The cache hierarchies also differ significantly. The i7-930 has 64 KB of L1 and 256 KB of L2 per core, with a large 8 MB shared L3 cache. The Athlon Silver 7120U doubles the L2 to 512 KB per core but has only 2 MB of shared L3. Memory support is another differentiator: the Intel part uses DDR3 in a triple-channel configuration, while the AMD chip uses LPDDR5 in a dual-channel setup with a rated bandwidth of 88.0 GB/s. The Athlon also features PCIe Gen 3 with 4 lanes (CPU only), whereas the i7-930 offers PCIe Gen 2. The i7-930 has no integrated graphics, but the Athlon includes a Radeon 610M iGPU.

Specification Differences

The specification sheets highlight how differently these two are engineered. The Intel Core i7-930 offers 4 cores and 8 threads, while the AMD Athlon Silver 7120U has 2 cores and 2 threads. Base clocks are 2.80 GHz for Intel and 2.40 GHz for AMD, but boost clocks reverse the order: 3.07 GHz for Intel and 3.50 GHz for AMD. The TDP gap is enormous: 130 watts versus 15 watts.

Their sockets and market segments are incompatible. The i7-930 uses Intel Socket 1366 and is a desktop part; the Athlon uses AMD Socket FT6 and is a mobile part. Process nodes differ (45 nm vs 6 nm), as do foundries (Intel vs TSMC). The memory bus widths and types are distinct: triple-channel DDR3 versus dual-channel LPDDR5. Cache configurations differ in L2 size (256 KB vs 512 KB per core) and L3 size (8 MB vs 2 MB). The i7-930 lacks integrated graphics, while the Athlon integrates a Radeon 610M. Their production statuses are also opposites: end-of-life versus active.

Head-to-Head Benchmarks

The head-to-head data provides the clearest verdict on where each chip stands. In Cinebench R15 multi-core, the Intel Core i7-930 scores 258 against the Athlon's 250, a narrow 3.2% win. This is the closest contest between the two, suggesting that in older, less optimized multi-threaded tests, the performance gap shrinks considerably.

The gap widens dramatically in Cinebench R23 multi-core. The i7-930 scores 2563, while the Athlon Silver 7120U manages only 1673. This 53.2% delta is the largest advantage for Intel in any test. The i7-930's 8 threads provide a clear scaling benefit in this modern, heavily threaded workload. The data shows that for sustained multi-core compute, the older chip is in a different league.

The tables turn completely in Cinebench R23 single-core. The AMD Athlon Silver 7120U scores 886, while the i7-930 trails far behind at 361. The delta is -59.3% from Intel's perspective, meaning the Athlon is nearly two and a half times faster. This result underscores the architectural leap in IPC (instructions per clock) that Zen 2 delivers over Nehalem, despite the Athlon's lower core count and lower base clock. For single-threaded performance, the modern chip is the undisputed winner.
