AMD Ryzen 5 3400GE vs Intel Core i5-1145G7E Comparison

The AMD Ryzen 5 3400GE and Intel Core i5-1145G7E are effectively performance twins in the Cinebench suite, with the Ryzen edging out a 6-0 win tally by the narrowest of margins. Across all six benchmark tests, the largest performance gap is a mere 0.1%, making these two processors indistinguishable in raw compute output. The data shows a dead heat that comes down to platform and feature differences rather than benchmark scores.

Head-to-Head Benchmarks

The benchmark results paint a picture of near-perfect parity. In Cinebench R15 multi-core, both processors score exactly 757 points, with the Ryzen 5 3400GE credited with the win due to a 0% delta. The single-core R15 test shows the same story: both score 106 points, again a 0% difference. These are not statistical victories; they are identical results.

Moving to Cinebench R20, the gap widens to a hair. The Ryzen 5 3400GE scores 3158 in multi-core against the Intel Core i5-1145G7E's 3156, a 0.1% delta. In single-core R20, both processors again post identical scores of 445 points. The pattern holds in Cinebench R23, where the AMD part scores 7520 multi-core versus 7516 for Intel (0.1% delta), and both hit 1061 in single-core.

The average benchmark score reinforces this picture: the Ryzen 5 3400GE averages 2175, while the Intel Core i5-1145G7E averages 2174, a 0.1% difference. Both processors sit at the 47th percentile among all CPUs, meaning they occupy the same performance tier relative to the broader market. The nearest rival comparison shows the Intel Core i7-1185GRE at 2178 (0.1% ahead of AMD, 0.2% ahead of Intel), but the two processors in question are effectively interchangeable in these tests.

Architecture Differences

Despite matching benchmark scores, these chips are built on fundamentally different architectures. The AMD Ryzen 5 3400GE uses the Zen+ architecture (codenamed Picasso) fabricated on a 12 nm process at GlobalFoundries, with a die size of 210 mm² and 4,940 million transistors. The Intel Core i5-1145G7E uses the Tiger Lake architecture (Willow Cove-U) on Intel's 10 nm process, with a smaller 144 mm² die.

Cache configurations diverge significantly. The AMD part provides 96 KB of L1 per core and 512 KB of L2 per core, with 4 MB of shared L3 cache. The Intel part offers 80 KB of L1 per core but a much larger 1.25 MB of L2 per core, and doubles the L3 to 8 MB shared. This larger cache pool on the Intel side does not translate into a benchmark advantage, suggesting the AMD memory hierarchy compensates effectively.

Memory support and PCIe also differ. The Ryzen 5 3400GE supports DDR4 only, with dual-channel memory and a stated bandwidth of 46.9 GB/s. The Intel part supports both DDR4 and LPDDR4X, also dual-channel, but lists no bandwidth figure. PCIe connectivity favors Intel: it supports Gen 4 with 4 lanes (CPU only), while AMD is limited to Gen 3. The integrated graphics differ too: AMD features Radeon RX Vega 11, while Intel relies on Iris Xe Graphics G7 80EU.

Clock speeds show a notable divergence. The AMD chip runs a base clock of 3.30 GHz and boosts to 4.00 GHz. The Intel chip has a dramatically lower base clock of 1500.00 MHz (1.50 GHz) but a higher boost of 4.10 GHz. This suggests the Intel part leans heavily on boost behavior, while the AMD chip maintains higher sustained clocks. TDP also differs: 35W for AMD versus 28W for Intel, indicating the Intel part is more power-efficient on paper.

FAQ

Q: Which processor wins the majority of benchmark tests?

A: The AMD Ryzen 5 3400GE wins all 6 head-to-head tests, but every victory is by a delta of 0% or 0.1%. The Intel Core i5-1145G7E does not win a single test.

Q: Are these processors truly equal in performance?

A: The benchmark data shows near-identical scores. In Cinebench R15 multi-core, both score 757; in R23 single-core, both score 1061. The largest gap is 2 points in R20 multi-core (3158 vs 3156), a 0.1% difference.

Q: How do these chips compare to other nearby CPUs?

A: Both sit at the 47th percentile. The AMD averages 2175, the Intel 2174. The closest rival, the Intel Core i7-1185GRE, scores 2178, which is 0.1% higher than AMD and 0.2% higher than Intel.

Q: What are the architectural differences that might matter?

A: Intel uses a 10 nm process with 8 MB L3 cache and 1.25 MB L2 per core, while AMD uses 12 nm with 4 MB L3 and 512 KB L2 per core. Intel also supports PCIe Gen 4, while AMD is Gen 3.

Q: Is the Intel chip more efficient?

A: The Intel Core i5-1145G7E has a 28W TDP versus 35W for AMD. The Intel base clock is much lower at 1.50 GHz, though it boosts to 4.10 GHz, slightly higher than AMD's 4.00 GHz boost.

Q: Which chip has better integrated graphics?

A: The AMD Ryzen 5 3400GE uses Radeon RX Vega 11, while the Intel part uses Iris Xe Graphics G7 80EU. The benchmark data does not include graphics tests, so performance cannot be compared from this pack.

The Verdict

The data points to a statistical tie with a technical edge to AMD on the scoreboard. The Ryzen 5 3400GE wins all six Cinebench tests, but with deltas of 0% or 0.1%, these wins carry no practical significance. The average benchmark scores differ by just 1 point (2175 vs 2174), and both chips land at the same 47th percentile.

The real differentiators are platform and features. The Intel Core i5-1145G7E offers a lower TDP (28W vs 35W), PCIe Gen 4 support, and twice the L3 cache (8 MB vs 4 MB). The AMD part counters with a higher base clock (3.30 GHz vs 1.50 GHz), a larger die (210 mm² vs 144 mm²), and a more traditional desktop socket (AM4 vs BGA 1449). The Intel chip is mobile-oriented with a launch MSRP of $312; the AMD part has no listed MSRP and targets desktop systems.

For users prioritizing raw compute in Cinebench workloads, either chip delivers identical results. The choice hinges on ecosystem: AMD's AM4 socket suggests upgrade flexibility, while Intel's BGA 1449 is soldered and mobile-focused. The Intel part's lower TDP and PCIe Gen 4 make it the more modern platform choice, but the AMD chip's higher sustained clocks and desktop heritage are meaningful for always-on systems.

Where Each One Wins

The AMD Ryzen 5 3400GE claims the benchmark scoreboard, winning all six Cinebench tests, though the margins are negligible. Its higher base clock of 3.30 GHz versus 1.50 GHz suggests better sustained performance in scenarios where boost clocks cannot be maintained, such as prolonged multi-threaded workloads on systems with limited cooling. The unlocked multiplier on the AMD part is another advantage for users who plan to overclock, assuming the platform allows it. The desktop AM4 socket and 35W TDP indicate suitability for small-form-factor desktop builds where consistent performance matters over battery life.

The Intel Core i5-1145G7E wins on platform modernity and efficiency. Its 28W TDP makes it the better choice for thermally constrained mobile or embedded systems. The 8 MB L3 cache, double the AMD's allocation, could benefit cache-sensitive workloads, even if Cinebench does not expose this advantage. PCIe Gen 4 support with 4 CPU lanes provides faster connectivity for NVMe storage or discrete GPUs. The higher boost clock of 4.10 GHz, though marginal, gives Intel the single-thread peak edge. The release date of 2020-09-01, over a year after AMD's 2019-07-06 launch, means Intel's platform is newer. The inclusion of LPDDR4X memory support further targets power-efficient mobile designs, while the $312 launch MSRP provides a reference point for procurement. For systems where power draw, PCIe bandwidth, or modern mobile integration are priorities, the Intel part holds the advantage despite losing every benchmark test.
