AMD Ryzen Embedded V1605B vs Intel Core i5-4460T Comparison

The AMD Ryzen Embedded V1605B and Intel Core i5-4460T are both four-core desktop processors, but they represent vastly different eras of design. The Ryzen is a modern, efficient part with simultaneous multithreading, while the Intel is an older, higher-power chip. Benchmark data shows a clear performance hierarchy, though the gap is not uniform across all workloads.

Head-to-Head Benchmarks

The most decisive result comes from the Cinebench R15 multi-core test. The AMD Ryzen Embedded V1605B scores 654, while the Intel Core i5-4460T manages only 313. That is a delta of 108.9% — the AMD part is more than twice as fast in this legacy multi-threaded workload. This massive advantage is directly attributable to the Ryzen's 8 threads versus the Intel's 4 threads, allowing it to process twice the parallel work simultaneously. For older applications that scale well with thread count, this is a total rout.

The story changes somewhat in the more modern Cinebench R23 multi-core test. Here, the Ryzen scores 3160 against the Intel's 3109, a much narrower 1.6% victory. This result is surprising given the R15 outcome, but it suggests that the newer benchmark is either better optimized for the Intel's Haswell architecture or that thermal and power constraints on the Ryzen's 15W TDP limit sustained performance under this heavier load. Regardless, the Ryzen still wins, but the margin is practically negligible.

Single-core performance shows another significant gap, though not as extreme as R15 multi-core. In Cinebench R23 single-core, the Ryzen scores 841 versus the Intel's 438, a 92% advantage. This is a strong indicator of the Ryzen's superior per-clock instructions per cycle (IPC) and its much higher boost clock of 3.60 GHz compared to the Intel's 2.70 GHz. This result means the Ryzen will feel snappier in everyday desktop tasks and lightly-threaded applications, from web browsing to office productivity.

The Intel does not win any of the head-to-head benchmarks listed. In the tests available, the AMD Ryzen Embedded V1605B takes all three wins. However, the Intel has a broader benchmark suite in the data, including Cinebench R20 and Geekbench tests, which are not directly compared head-to-head. In the absent Cinebench R20 multi-core test, the Intel scores 1305, and its Geekbench multi-core score is 2170. Without a corresponding Ryzen score for those specific tests, a direct comparison is impossible, so the analysis must rest on the provided head-to-head data.

The Verdict

The data presents a straightforward case for most users. The AMD Ryzen Embedded V1605B is the superior processor in every head-to-head metric available. It offers a commanding lead in single-core performance (92% in Cinebench R23) and a massive win in the older multi-core test (108.9% in Cinebench R15). Even where the margin shrinks, as in Cinebench R23 multi-core, the Ryzen still comes out ahead.

The Intel Core i5-4460T, by contrast, only holds its own in the one modern multi-threaded benchmark where it trails by just 1.6%. Given that the Ryzen also does so while consuming less than half the power (15W TDP versus 35W), there is no performance-based argument for choosing the Intel part. The Ryzen is the clear pick for any workload that values compute performance, efficiency, or responsiveness.

The only reason to consider the Intel Core i5-4460T would be platform-specific requirements. It uses the Intel Socket 1150 and supports DDR3 memory, while the Ryzen uses AMD Socket FP5 and DDR4. If you are building on an existing 1150 motherboard or have a stock of DDR3 RAM, the Intel part might be a drop-in option. However, from a pure performance and power standpoint, the Ryzen is the definitive winner.

Architecture Differences

These two CPUs are built on fundamentally different architectures from different generations. The AMD Ryzen Embedded V1605B uses the Zen architecture, produced on a 14 nm process by GlobalFoundries. It features 4 cores and 8 threads, with a base clock of 2000.00 MHz and a boost clock of 3.60 GHz. It has a 15W TDP and uses the AMD Socket FP5.

The Intel Core i5-4460T is based on the much older Haswell architecture, manufactured on Intel's 22 nm process. It has 4 cores and 4 threads, with a base clock of 1900.00 MHz and a boost clock of 2.70 GHz. Its TDP is higher at 35W, and it uses the Intel Socket 1150.

The cache configurations differ significantly. The Ryzen allocates 128 KB of L1 and 512 KB of L2 per core, with a 2 MB shared L3 cache. The Intel part has smaller per-core caches, with 64 KB of L1 and 256 KB of L2 per core, but a larger 6 MB shared L3 cache. The larger L3 on the Intel may help in some cache-sensitive workloads, but the benchmark data shows that the Ryzen's other advantages outweigh this.

Memory support also diverges. The Ryzen supports DDR4 memory on a dual-channel bus, while the Intel supports DDR3 with a dual-channel bus and has a stated memory bandwidth of 25.6 GB/s. The Ryzen's memory bandwidth is not listed, but the newer DDR4 standard typically offers higher bandwidth. Neither processor supports ECC memory, and both have locked multipliers.

Where Each One Wins

The AMD Ryzen Embedded V1605B wins in every directly compared benchmark category. It is the clear choice for multi-threaded workloads, as evidenced by its 108.9% lead in Cinebench R15 multi-core. It is also the better option for single-threaded tasks, with a 92% lead in Cinebench R23 single-core. This combination makes it superior for general desktop use, content creation, and any application that can leverage multiple threads. Its lower TDP also makes it more suitable for compact or passively cooled systems where heat and power are primary concerns.

The Intel Core i5-4460T, despite having zero head-to-head wins, still has a niche. Its only close result is in Cinebench R23 multi-core, where it trails by just 1.6%. This suggests that in a specific, modern, heavily-threaded workload that fits within its 6 MB L3 cache, the performance difference is minimal. The Intel part could also be the only option for a builder who already owns a Socket 1150 motherboard and DDR3 memory and wants to avoid a platform upgrade. Its production status is end-of-life, but it remains a functional, if dated, component.
