CPU Comparison

The AMD A8-7680 and AMD Ryzen Embedded V1202B are two very different processors that land in the same performance neighborhood. The A8-7680 is a 4-core, 4-thread desktop part built on the older Excavator architecture, while the V1202B is a 2-core, 4-thread embedded chip based on the newer Zen design. Despite their architectural gap, the benchmark data shows them trading blows at nearly identical scores, with the A8-7680 holding a narrow edge across every recorded Cinebench test.

Where Each One Wins

The data is unambiguous here: the AMD A8-7680 wins all five head-to-head benchmark comparisons. Its margin of victory is consistent but small, ranging from 0.9% to 1.1% depending on the test. The largest win comes in Cinebench R20 single-core, where the A8-7680 scores 178 against the V1202B’s 176, a 1.1% advantage. In multi-core workloads, the A8-7680 leads by 0.9% in both Cinebench R20 and R23, and by 1% in Cinebench R15.

This means the A8-7680 is the better choice for pure compute throughput, whether the workload is single-threaded or multi-threaded. The V1202B, however, does not win a single benchmark in this dataset. Its relevance comes from context: the V1202B achieves nearly the same scores with only 2 physical cores and a 15W TDP, compared to the A8-7680’s 4 cores and 45W TDP. The data suggests the V1202B is the more efficient option, but the A8-7680 is the faster one in absolute terms.

For users prioritizing raw Cinebench performance, the A8-7680 is the clear winner. For those who care about power efficiency and platform modernity, the V1202B’s near-parity results are more impressive given its lower core count and TDP.

Head-to-Head Benchmarks

The head-to-head results paint a picture of extreme parity. In Cinebench R15 multi-core, the A8-7680 scores 303 against the V1202B’s 300, a 1% difference. That is roughly a 3-point gap, which is within the noise of many real-world workloads, but it still represents a consistent trend.

Moving to Cinebench R20 multi-core, the A8-7680 posts 1264 while the V1202B delivers 1253. The delta is 0.9%, meaning the A8-7680 is just 11 points ahead. The single-core R20 test shows a similar story: 178 versus 176, a 1.1% edge for the A8-7680.

The Cinebench R23 results follow the same pattern. In multi-core, the A8-7680 scores 3011 against 2985 for the V1202B, a 0.9% lead. In single-core, the A8-7680 hits 425 while the V1202B reaches 421, a 1% advantage. Across all five tests, the A8-7680 wins every time, but the largest margin is just 1.1%.

What does this mean? The V1202B is not a weak performer; it is remarkably close to the A8-7680 despite having half the physical cores. The Zen architecture in the V1202B is clearly more efficient per core, as evidenced by the near-identical scores. However, the A8-7680’s two extra cores give it a slight edge in every scenario measured here. The data does not show any test where the V1202B pulls ahead, so the A8-7680 is objectively the faster chip in this comparison.

Specification Differences

The two processors differ in almost every major specification. The A8-7680 has 4 cores and 4 threads, while the V1202B has 2 cores and 4 threads. Clock speeds favor the A8-7680, which runs at 3.50 GHz base and 3.80 GHz boost, compared to the V1202B’s 2.30 GHz base and 3.20 GHz boost. The TDP gap is substantial: 45W for the A8-7680 versus 15W for the V1202B.

Sockets are completely different: the A8-7680 uses AMD Socket FM2+, while the V1202B uses AMD Socket FP5. The process node also differs, with the A8-7680 built on 28 nm and the V1202B on 14 nm. Both are manufactured by GlobalFoundries, but the transistor counts diverge sharply: 3,100 million for the A8-7680 versus 4,950 million for the V1202B. The die size is 250 mm² for the A8-7680 and 210 mm² for the V1202B.

Cache configurations are not directly comparable. The A8-7680 has 320 KB of L1 cache and 2 MB of L2 cache, with no L3 cache listed. The V1202B has 128 KB of L1 cache per core, 512 KB of L2 cache per core, and 2 MB of shared L3 cache. Memory support differs as well: the A8-7680 uses DDR3 with 34.1 GB/s bandwidth, while the V1202B uses DDR4 with no bandwidth figure provided. Both support dual-channel memory and neither supports ECC.

The integrated graphics differ, with the A8-7680 featuring Radeon R7 and the V1202B featuring Radeon Vega 3. The A8-7680 lists PCIe Gen 3 support, while the V1202B has no PCIe specification listed. Release dates are about eight months apart, with the V1202B launching on 2018-02-20 and the A8-7680 on 2018-10-25. Neither chip has a launch MSRP listed, and neither has an unlocked multiplier.

Architecture Differences

The architectural gap between these two is significant. The A8-7680 is based on the Excavator architecture under the Carrizo codename, while the V1202B uses the Zen architecture under the same Zen codename (part of the "Great Horned Owl" generation). Excavator is a mature, high-clock design from AMD’s Bulldozer lineage, while Zen is a ground-up redesign focused on instructions per clock and power efficiency.

The process node tells part of the story: 28 nm for the A8-7680 versus 14 nm for the V1202B. This explains why the V1202B can achieve comparable performance at a much lower TDP. The transistor count is also revealing: the V1202B packs 4,950 million transistors into a 210 mm² die, while the A8-7680 uses 3,100 million transistors across a 250 mm² die. The V1202B is denser and more efficient.

Cache architecture differs fundamentally. The A8-7680 uses a shared L2 cache of 2 MB with no L3, while the V1202B uses per-core L1 and L2 caches (128 KB and 512 KB per core, respectively) plus a 2 MB shared L3. This reflects the different design philosophies: Excavator relies on a larger shared L2, while Zen uses a hierarchical cache with a dedicated L3.

The integrated graphics also reflect the generational shift. The A8-7680 uses Radeon R7, which is based on older GCN-era technology. The V1202B uses Radeon Vega 3, a newer architecture that benefits from the 14 nm process. The memory support difference (DDR3 versus DDR4) further highlights the generational divide, with the V1202B designed for more modern platforms.

The Verdict

Based strictly on the benchmark data, the AMD A8-7680 is the faster processor. It wins all five head-to-head Cinebench tests with margins between 0.9% and 1.1%. Its average benchmark score of 1036 also tops the V1202B’s 1027. For anyone who needs maximum compute performance in the specific workloads measured, the A8-7680 is the clear pick.

However, the V1202B deserves consideration for different reasons. It achieves nearly identical scores with 2 fewer physical cores and a 15W TDP versus 45W. The per-core efficiency of the Zen architecture is evident, and the V1202B’s 14 nm process and DDR4 support make it a more modern platform. The V1202B also has L3 cache, which the A8-7680 lacks entirely.

The choice comes down to priorities. If raw Cinebench scores are the only metric, the A8-7680 wins, but the margin is so thin that it may not matter in real-world use. If power efficiency, platform modernity, and architectural sophistication matter more, the V1202B’s near-parity performance makes it the more compelling engineering achievement. The data shows a tie in performance percentile (both at 28%), reinforcing that these chips are effectively equals in the broader CPU landscape. The A8-7680 is the winner on paper; the V1202B is the winner on efficiency.
