AMD Ryzen 5 5605GE vs Intel Core 3 305 Comparison

Architecture Differences

The AMD Ryzen 5 5605GE and Intel Core 3 305 represent fundamentally different design philosophies. The Ryzen 5 5605GE is built on AMD's Zen 3 architecture using the Cezanne codename, fabricated on a 7 nm process at TSMC with 10,700 million transistors on a 180 mm² die. It features 6 cores and 12 threads, with a base clock of 3.40 GHz and a boost clock of 4.40 GHz. The Intel Core 3 305, by contrast, uses the Wildcat Lake codename on Intel's own 3 nm process, with 6 cores but only 6 threads. Its base clock sits at 1.50 GHz, boosting to 4.30 GHz.

Cache configurations differ sharply. The AMD part allocates 64 KB of L1 per core and 512 KB of L2 per core, totaling 16 MB of L3 cache. The Intel processor lists 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The Ryzen's larger L3 pool gives it an advantage in workloads that repeatedly access a working set larger than 6 MB.

Memory architecture also diverges. The Ryzen 5 5605GE supports DDR4 on a dual-channel bus with 51.2 GB/s bandwidth. The Core 3 305 supports DDR5 and LPDDR5X on a single-channel bus, yet reaches 59.7 GB/s bandwidth. Despite having only one channel, the newer memory standard delivers higher theoretical bandwidth.

Platform differences are substantial. The AMD chip uses Socket AM4 with PCIe Gen 3 and 16 CPU lanes, and its multiplier is unlocked for overclocking. The Intel part uses BGA 1516, a soldered mobile socket, with PCIe Gen 4 and only 6 CPU lanes, and its multiplier is locked. The Intel processor targets the mobile segment, while the AMD processor is a desktop part. Both integrate graphics: Radeon Vega 7 on the AMD side, Intel Xe3 Graphics with 1 Xe core on the Intel side. Neither supports ECC memory. The Intel chip has a launch MSRP of $309.

The Verdict

The data indicates a clear winner for multithreaded throughput: the AMD Ryzen 5 5605GE. Its 12 threads versus 6 threads, combined with a much higher base clock of 3.40 GHz versus 1.50 GHz, gives it a structural advantage in any workload that can use more than six threads. The 7 nm process and larger L3 cache reinforce this lead in sustained compute.

The Intel Core 3 305 wins on efficiency and platform modernity. Its 15 W TDP versus 35 W for the AMD part makes it the choice for thermally constrained or battery-powered systems. The 3 nm process from Intel, the newer DDR5/LPDDR5X memory support, and PCIe Gen 4 connectivity are meaningful for compact or mobile designs where power and board space matter more than raw core count.

For desktop users who value multithreaded performance, overclocking freedom, and an established AM4 ecosystem, the Ryzen 5 5605GE is the stronger pick. For users building ultra-low-power or mobile systems that need modern memory and PCIe standards, the Core 3 305 is the better fit. The benchmark data supports this split: the Intel chip holds a 72nd percentile ranking among all CPUs, while the AMD chip's percentile is 50, but the AMD part has no recorded benchmark scores in the database, so direct score comparisons cannot be made.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Ryzen 5 5605GE versus the Intel Core 3 305. The AMD processor's benchmark array is empty, meaning no recorded scores exist in the database. The Intel Core 3 305, however, has a full suite of recorded results.

The Intel chip's Cinebench R23 multicore score is 13123, with a single-core score of 1852. In Cinebench R20, it scores 5511 multicore and 777 single-core. Its Cinebench R15 results are 1322 multicore and 186 single-core. PassMark results include 15439 for multithread, 3977 for single-thread, 146857 for data compression, 11019 for data encryption, 13543 for extended instructions, 115 for find prime numbers, 42284 for floating point math, 32295 for integer math, 1233 for physics, and 17623 for random string sorting.

The nearest rivals to the Intel Core 3 305 in the database provide context. The Intel Core i3-14100 scores 18318 on average, which is 0.1% lower than the Core 3 305's average of 18302. The Intel Core 5 330 averages 18345, 0.2% higher. The Intel Core 7 360 averages 18374, 0.4% higher. The AMD Ryzen 5 2600E averages 18230, 0.4% lower. The Core 3 305 slots between these four parts, all within a 0.8% band. This tight clustering indicates the Core 3 305 delivers performance on par with a recent i3-class part and a Ryzen 5 2600E.

Because the AMD Ryzen 5 5605GE has no benchmark scores, a numerical head-to-head comparison is impossible. The analysis must rely on architectural specifications. The AMD chip's 12 threads, 4.40 GHz boost clock, and 16 MB L3 cache suggest strong multithreaded capability. The Intel chip's 6 threads and 4.30 GHz boost clock limit its multithreaded ceiling. In single-threaded work, the boost clocks are close, with a 0.10 GHz difference favoring AMD.

Where Each One Wins

The AMD Ryzen 5 5605GE wins in multithreaded throughput by design. Its 12 threads double the Intel part's 6 threads. The higher base clock of 3.40 GHz versus 1.50 GHz means it maintains far higher performance when all cores are active at lower loads. The 16 MB L3 cache versus 6 MB favors workloads with large reused datasets, such as compilation, rendering, or scientific computing. The unlocked multiplier allows users to push clocks beyond stock settings, which the locked Intel chip cannot do. The AM4 socket also supports a wide range of existing motherboards, which the BGA 1516 soldered design does not offer.

The Intel Core 3 305 wins in power efficiency and platform features. Its 15 W TDP is less than half the AMD part's 35 W, making it suitable for thin-and-light laptops or fanless designs. The 3 nm process node from Intel gives it a manufacturing advantage in density and power draw. DDR5 and LPDDR5X memory support brings higher bandwidth per pin and lower voltage operation. PCIe Gen 4 with 6 lanes, while fewer lanes than the AMD's 16 Gen 3 lanes, offers higher per-lane bandwidth for NVMe drives and modern GPUs. The single-channel memory bus is a limitation, but the 59.7 GB/s bandwidth still exceeds the AMD's dual-channel DDR4 figure.

The benchmark percentile data reinforces the split. The Intel Core 3 305 ranks at the 72nd percentile among all CPUs in the database. The AMD Ryzen 5 5605GE ranks at the 50th percentile, but with no recorded benchmark scores, its percentile reflects an unverified default. The Intel chip's average benchmark score of 18302 places it in the upper-middle range of the database, within 0.4% of the Core 7 360 and Core 5 330, and just 0.1% above the Core i3-14100.

For workloads dominated by integer math, the Intel chip scores 32295 in PassMark integer math and 42284 in floating point math. For data compression, it hits 146857. These are strong absolute numbers for a 15 W mobile processor. The AMD chip, lacking recorded scores, cannot be compared numerically, but its architectural advantages in thread count and cache size point to superiority in heavily parallel tasks.
