AMD A8-7680 vs Intel Core i3-4340 Comparison

Head-to-Head Benchmarks

The recorded data shows a consistent, though narrow, advantage for the AMD A8-7680 across every Cinebench test in the head-to-head comparison. The AMD part wins all five recorded benchmarks, but the margins are uniformly small, ranging from 0.9% to 1.1%. In multi-core workloads, the A8-7680 scores 303 in Cinebench R15 against 300 for the Core i3-4340, a 1% lead. The R20 multi-core test shows 1264 versus 1252, again a 1% delta. The R23 multi-core result is 3011 versus 2983, a 0.9% edge.

Single-core performance tells the same story. The A8-7680 records 178 in Cinebench R20 single-core, beating the Intel part's 176 by 1.1%. In R23 single-core, the scores are 425 and 421, a 1% difference. These are not transformative wins; they sit at the margin of run-to-run variance. The database's average benchmark scores place the A8-7680 at 1036 and the Core i3-4340 at 1026, meaning the AMD chip holds roughly a 1% aggregate lead. Both processors land at the 28th percentile among all CPUs, indicating that neither is positioned as a high-performance part by current standards.

The nearest rivals for the A8-7680 include the AMD A10-7890K with a 0.1% higher average score, the Intel Core i7-4558U with a -0.2% delta, and the AMD A12-9800E at 0.3%. For the Core i3-4340, its closest neighbors are the Intel Processor N150 (0.1%), Intel Core i7-5650U (-0.1%), and AMD Ryzen Embedded V1202B (-0.1%). In both cases, the immediate competition is extremely tight, and the head-to-head delta between the A8-7680 and i3-4340 is smaller than the gaps to some of their own nearest rivals. The recorded data does not support calling either chip a clear winner on raw compute alone.

Architecture Differences

The two processors come from fundamentally different design lineages. The AMD A8-7680 uses the Excavator architecture, which is the final iteration of AMD's Steamroller-derived line, codenamed Carrizo. It is built on a 28 nm process at GlobalFoundries, with 3,100 million transistors on a 250 mm² die. The Intel Core i3-4340 uses the Haswell architecture, codenamed Haswell, built on Intel's 22 nm process, with 1,400 million transistors on a 177 mm² die. The transistor counts and die sizes differ significantly: the AMD chip packs over twice the transistor count but on a larger die, while the Intel chip uses a smaller, more refined node.

The core configurations differ as well. The AMD A8-7680 offers 4 physical cores and 4 threads, while the Intel Core i3-4340 has 2 physical cores but 4 threads via Hyper-Threading. The AMD chip runs at a base clock of 3.50 GHz with a boost clock of 3.80 GHz. The Intel part has a base clock of 3.60 GHz and no listed boost clock. This means the Intel chip has a higher base frequency, but the AMD part can reach a higher peak frequency via boost.

Cache hierarchies are notably different. The AMD chip has 320 KB of L1 cache and 2 MB of L2 cache, with no L3 cache. The Intel part lists 64 KB per core for L1 (which for two cores totals 128 KB), 256 KB per core for L2 (512 KB total), and a shared 4 MB L3. The Intel design provides an L3 cache that the AMD lacks entirely. The lack of L3 on the AMD side may impact certain workloads, but the recorded benchmarks do not show a meaningful difference in the tested Cinebench suite.

Memory support is similar on the surface: both support DDR3 in dual-channel mode. The AMD lists a theoretical memory bandwidth of 34.1 GB/s; the Intel does not list a bandwidth. Neither supports ECC memory. Both use PCIe Gen 3, though the exact lane counts are not provided. Integrated graphics differ: AMD includes Radeon R7 graphics, while Intel uses HD 4600. No performance numbers for the integrated GPUs are in the database.

Process node, foundry, and transistor counts are direct contrasts. The AMD chip uses a 28 nm process from GlobalFoundries, while the Intel chip uses a 22 nm process from Intel. This gives Intel a density advantage, as it fits fewer transistors in a smaller die. The release dates also differ: the Core i3-4340 appeared in Q3 2013, while the A8-7680 landed in Q4 2018, about five years later.

Specification Differences

The two processors differ in several measurable fields. The AMD A8-7680 has 4 cores and 4 threads; the Intel Core i3-4340 has 2 cores and 4 threads. Base clocks are 3.50 GHz (AMD) versus 3.60 GHz (Intel). The AMD part has a boost clock of 3.80 GHz; the Intel has no listed boost clock. TDP differs: 45 watts for AMD, 54 watts for Intel. Sockets differ: AMD Socket FM2+ for the A8-7680, Intel Socket 1150 for the Core i3-4340.

The architecture names differ: Excavator versus Haswell. The process nodes are 28 nm versus 22 nm. Transistor counts are 3,100 million versus 1,400 million, and die sizes are 250 mm² versus 177 mm². Cache configurations are different: the AMD has 320 KB L1 and 2 MB L2, no L3; the Intel has 64 KB L1 per core, 256 KB L2 per core, and 4 MB shared L3. Memory bandwidth is listed at 34.1 GB/s for the AMD, no listing for the Intel. The integrated graphics are Radeon R7 for AMD and Intel HD 4600 for Intel.

The release dates differ by more than five years: the Intel chip's release date is August 31, 2013, while the AMD chip's is October 25, 2018. The production status is "Active" for the AMD part, null for the Intel part. The part number for the AMD is "AD7680ACABBOX\nAD7680ACABCBX", for the Intel it is "SR1NL". Neither has a launch MSRP, and both have the multiplier locked.

The Verdict

The data shows a narrow but consistent victory for the AMD A8-7680. It wins all five head-to-head Cinebench tests, with the largest margin being 1.1% in R20 single-core. Its average benchmark score of 1036 is 10 points higher than the Core i3-4340's 1024. However, this margin is small enough to be considered within run-to-run variance for most real-world users. The percentile rankings are identical at 28%, meaning both chips sit in the same performance tier.

The Core i3-4340 does not have a single benchmark win in the recorded data. Its strengths are not visible in the Cinebench collection. The A8-7680, on the other hand, wins across the board, even if by small margins. For a user who values raw multi-core throughput in rendering workloads (Cinebench), the A8-7680 is the safer pick. For a user who values lower TDP, the A8-7680 also leads, at 45 watts versus 54 watts.

The Intel part does offer a shared L3 cache of 4 MB, which the AMD lacks, but the benchmark data does not show this translating into a win. The Intel also has a higher base clock (3.60 GHz) but no boost clock, while the AMD has a lower base but a 3.80 GHz boost. In a short burst, the AMD's boost can push it ahead, as the single-core results show.

There is no launch MSRP for either, meaning price-based analysis is not possible from the given data. Both are locked multipliers, so overclocking is not a differentiator. The AMD A8-7680 is the better processor in this comparison, but the margin is thin. The AMD A8-7680 is the better processor in this comparison, but the margin is thin.

Where Each One Wins

The AMD A8-7680 wins in every recorded benchmark, so the use-case split is clear for multi-threaded rendering: it is the stronger choice in Cinebench R15, R20, and R23 multi-core tests, with deltas of 1%, 1%, and 0.9% respectively. It also wins in single-core tests, with 1.1% and 1% margins in R20 and R23. If the workload is any of the tested Cinebench scenarios, the A8-7680 is the recommended chip.

The Intel Core i3-4340 does not have a single recorded win. However, it does have a lower TDP than the AMD part? No, it has a higher TDP (54W vs 45W). The Intel chip's only listed advantages are a higher base clock (3.60 GHz vs 3.50 GHz) and a larger L3 cache (4 MB vs none). For users who rely on base-clock sustained performance over a boost burst, the Intel might be preferable, but the benchmark data does not support that outcome. For a system builder who values a 45W TDP part for a low-power build, the AMD A8-7680 is the better choice.

The AMD part also supports a boost clock, which the Intel does not. This means the AMD has the ability to raise its frequency from 3.50 GHz to 3.80 GHz when thermal headroom allows, a feature absent on the Intel side. In short, the recorded data shows the A8-7680 winning in every single benchmark test, making it the default pick for any Cinebench-style workload. The Core i3-4340 does not demonstrate an area where it wins, so there is no measured scenario where it should be chosen over the A8-7680 based on the provided facts.
