AMD Ryzen Embedded V1807B vs Intel Core i5-1145GRE Comparison

The Intel Core i5-1145GRE and AMD Ryzen Embedded V1807B are both 4-core, 8-thread processors aimed at compact, power-conscious systems, yet they represent fundamentally different design philosophies. The data reveals a striking pattern: across all six Cinebench benchmarks, the Intel part wins every single contest, but the margin of victory is consistently razor-thin, ranging from just 0.5% to 1.0%. This near-parity in raw scores, combined with dramatic differences in architecture, power envelopes, and platform features, makes this comparison less about outright speed and more about the specific trade-offs each chip demands.

Where Each One Wins

The benchmark results paint a clear picture of overall parity, but the underlying specs suggest different ideal use cases. The Intel Core i5-1145GRE wins all six head-to-head Cinebench tests, including a 0.6% edge in Cinebench R23 multi-core (7001 vs 6957) and a 1.0% advantage in Cinebench R15 single-core (99 vs 98). These wins, while consistent, are within the margin of noise for most real-world workloads. The real differentiator is not performance but the platform around it.

The Intel chip is a mobile Tiger Lake-U part with a 28W TDP, making it the clear choice for fanless or lightly-cooled embedded laptops, thin clients, and rugged tablets. Its 10 nm process node and Willow Cove cores deliver competitive performance at roughly 62% of the AMD part's power budget (28W vs 45W). The Intel chip also supports ECC memory, a critical feature for reliability-focused embedded applications like network appliances or industrial controllers. Its PCIe Gen 4 interface, albeit limited to 4 CPU lanes, offers modern connectivity for fast NVMe storage or discrete accelerators.

The AMD Ryzen Embedded V1807B, by contrast, is a 45W desktop-class part built on a 14 nm process. It compensates for higher power draw with a substantially higher base clock of 3.35 GHz versus the Intel's 1.50 GHz, though the Intel boosts higher (4.10 GHz vs 3.80 GHz). The AMD chip features the Radeon RX Vega 11 integrated graphics, which is a significantly more powerful GPU than Intel's Iris Xe Graphics G7 80EU for graphics-intensive tasks like digital signage, light gaming, or GPU-accelerated compute. The AMD part also has a larger L1 cache (128 KB per core vs 80 KB per core), which can benefit certain latency-sensitive workloads.

Architecture Differences

These chips are separated by more than just brand; they represent two distinct architectural eras. The Intel Core i5-1145GRE uses the Tiger Lake-U architecture built on Intel's 10 nm process with a die size of 144 mm². It features Willow Cove cores, a modern microarchitecture designed for high single-thread performance and efficiency. The cache hierarchy is notable: 1.25 MB of L2 cache per core and 8 MB of shared L3 cache. This generous L3 allocation helps the chip maintain performance despite its lower base clock.

The AMD Ryzen Embedded V1807B uses the first-generation Zen architecture on GlobalFoundries' 14 nm process, with a larger die size of 210 mm² and 4,950 million transistors. Its cache layout is different: 128 KB L1 per core, 512 KB L2 per core, and only 2 MB of shared L3 cache. The smaller L3 cache is a significant architectural difference, as modern workloads often benefit from larger shared pools. The AMD part compensates with a much higher base clock (3.35 GHz), which helps close the gap in single-threaded performance but at the cost of higher power consumption.

Memory support also diverges. Both support dual-channel DDR4, but the Intel chip also supports LPDDR4X, which enables lower-power memory configurations common in mobile devices. The AMD chip supports only standard DDR4, limiting its use in ultra-portable designs. The Intel chip supports ECC memory, while the AMD part does not, making the Intel part more suitable for error-sensitive computing environments.

The Verdict

The data suggests a clear if narrow performance winner, but the choice depends heavily on platform requirements. The Intel Core i5-1145GRE is the better choice for applications where power efficiency, ECC memory support, and modern connectivity (PCIe Gen 4) are paramount. Its 28W TDP and LPDDR4X support make it ideal for battery-powered or passively-cooled devices. The 0.6% to 1.0% performance lead across all Cinebench tests is a bonus, not the primary reason to select it.

The AMD Ryzen Embedded V1807B is the better choice for applications that need robust integrated graphics or are willing to trade power for a higher base clock. Its 45W TDP precludes it from the most power-constrained designs, but the Radeon RX Vega 11 GPU offers substantially more graphics horsepower. For embedded systems that require GPU compute, video transcoding, or rich visual output, the AMD part is the stronger contender despite losing every CPU benchmark.

Neither chip is a clear winner on raw CPU performance; the largest delta is 1.0% in Cinebench R15 single-core. The decision rests on non-CPU factors. The Intel part is the more versatile, modern platform; the AMD part is a high-power workhorse with a superior GPU.

Head-to-Head Benchmarks

The Cinebench results show a stunningly consistent pattern: the Intel Core i5-1145GRE wins every test, but never by more than 1.0%. The largest single-core margin is in Cinebench R15, where Intel scores 99 against AMD's 98, a 1.0% advantage. This is the only test where the delta exceeds 0.7%, suggesting that Intel's higher boost clock (4.10 GHz vs 3.80 GHz) provides a slight edge in lightly-threaded workloads.

In multi-core tests, the margins tighten further. Cinebench R15 multi-core shows Intel at 705 vs AMD at 701, a 0.6% lead. Cinebench R20 multi-core shows 2940 vs 2921, a 0.7% lead. Cinebench R23 multi-core shows 7001 vs 6957, again a 0.6% lead. These results are remarkably consistent, indicating that the two chips are thermally and architecturally equivalent in sustained multi-threaded loads, despite the AMD part's higher base clock and the Intel part's superior L3 cache.

Single-core results follow the same pattern. Cinebench R20 single-core shows Intel at 414 vs AMD at 412, a 0.5% lead. Cinebench R23 single-core shows 988 vs 982, a 0.6% lead. The Intel chip's advantage here is likely due to its newer Willow Cove architecture, which offers better IPC than the original Zen design. The AMD chip's higher base clock (3.35 GHz) helps it stay close, but cannot fully overcome the architectural deficit.

The aggregate benchmark scores confirm the trend. The Intel Core i5-1145GRE has an average benchmark score of 2025, while the AMD Ryzen Embedded V1807B scores 2012, a difference of 0.6%. Both CPUs sit at the 45th percentile of all CPUs, placing them in the same performance tier. The nearest rivals for the Intel chip are other 45th-percentile parts like the Core i5-1130G7 (delta -0.1%) and Xeon E3-1260L v5 (delta -0.2%), while the AMD chip's nearest rivals include the Ryzen 7 1700 (delta -0.1%) and Core i5-8300H (delta +0.3%).

Specification Differences

The two processors differ across nearly every major specification category, reflecting their different design goals. The most significant difference is in power: the Intel Core i5-1145GRE has a 28W TDP, while the AMD Ryzen Embedded V1807B has a 45W TDP. This 17W gap is crucial for thermal design and battery life.

Clock speeds also diverge sharply. The Intel chip has a base clock of 1.50 GHz and a boost clock of 4.10 GHz. The AMD chip has a base clock of 3.35 GHz and a boost clock of 3.80 GHz. The AMD part runs faster at idle and lower loads, but the Intel part has a higher ceiling.

The process node differs: Intel uses 10 nm, while AMD uses 14 nm. This explains the Intel chip's lower power draw despite similar performance. The die sizes also differ, with Intel at 144 mm² and AMD at 210 mm². The AMD chip has 4,950 million transistors, while the Intel chip's transistor count is not listed.

Cache configurations are fundamentally different. The Intel chip has 80 KB L1 per core, 1.25 MB L2 per core, and 8 MB shared L3. The AMD chip has 128 KB L1 per core, 512 KB L2 per core, and only 2 MB shared L3. The Intel chip's larger L3 cache is a major architectural advantage for multi-threaded workloads.

Memory support shows the Intel chip supporting both DDR4 and LPDDR4X, while the AMD chip supports only DDR4. The Intel chip supports ECC memory; the AMD chip does not. PCIe support is only listed for the Intel chip (Gen 4, 4 lanes), while the AMD chip's PCIe configuration is not specified.

The integrated graphics differ: Intel uses Iris Xe Graphics G7 80EU, while AMD uses Radeon RX Vega 11. The Intel chip is marked for Mobile market segment, while the AMD chip is for Desktop. The Intel chip has a launch MSRP of $362; the AMD chip has no listed launch MSRP. Both chips are currently Active in production and have locked multipliers.
