Supports 64-bit

Both the Intel 300 and the Intel Core Ultra 3 205 are desktop processors that share a solid common foundation: integrated graphics, PCIe 5 support, and 64-bit compatibility. These shared traits mean both chips can handle modern storage and GPU bandwidth requirements without bottlenecking contemporary hardware.

The most meaningful differentiator in this group is the manufacturing process. The Intel 300 is built on a 10 nm node, while the Core Ultra 3 205 uses a significantly more advanced 3 nm process. In practical terms, a smaller node typically translates to better power efficiency and higher transistor density — which helps explain why the Core Ultra 3 205 can operate at a higher thermal ceiling (105 °C vs 100 °C) while also carrying a higher TDP of 57W compared to the Intel 300's leaner 46W. The higher TDP of the 205 suggests it is designed to sustain more demanding workloads, trading raw efficiency for greater sustained performance headroom. The two chips also target different platform generations: the Intel 300 uses the LGA 1700 socket, while the Core Ultra 3 205 requires the newer LGA 1851, meaning they are not interchangeable and dictate different motherboard ecosystems.

On general platform specs alone, the Core Ultra 3 205 holds a clear architectural edge thanks to its far more modern process node and newer socket platform, making it the more future-oriented choice. The Intel 300, however, benefits from a lower TDP, which may appeal to users prioritizing energy efficiency or building compact, low-power systems on the mature LGA 1700 platform.

Performance:
CPU speed 2 x 1 GHz 4 x 3.8 & 4 x 3.2 GHz
CPU threads 4 threads 8 threads
turbo clock speed 3.9GHz 4.9GHz
Has an unlocked multiplier
L2 cache 2.5 MB 16 MB
Uses big.LITTLE technology
clock multiplier 39 38

The Intel 300 and Intel Core Ultra 3 205 differ significantly in their performance specifications. The Intel 300 has a CPU speed of 2 x 1 GHz, with a turbo clock speed of 3.9 GHz and 4 threads. In contrast, the Intel Core Ultra 3 205 features a more powerful CPU speed of 4 x 3.8 GHz & 4 x 3.2 GHz, with a turbo clock speed of 4.9 GHz and 8 threads. This indicates a higher base clock and more processing threads for the Intel Core Ultra 3 205.

Both processors have an L2 cache, but the Intel 300 has 2.5 MB, while the Intel Core Ultra 3 205 has a significantly larger 16 MB L2 cache. Additionally, neither processor has an unlocked multiplier, meaning neither can be easily overclocked. The clock multiplier for the Intel 300 is 39, while the Intel Core Ultra 3 205 has a slightly lower multiplier of 38.

Another key difference is that the Intel Core Ultra 3 205 uses big.LITTLE technology, which the Intel 300 does not. This technology allows the Intel Core Ultra 3 205 to dynamically balance performance and efficiency by using different types of cores for different workloads.

Integrated graphics:
GPU clock speed 300 MHz 300 MHz
GPU turbo 1450 MHz 1800 MHz
DirectX version DirectX 12 DirectX 12
supported displays 4 4
OpenGL version 4.5 4.5
OpenCL version 3 3

The integrated graphics of the Intel 300 and Intel Core Ultra 3 205 are quite similar, but there are some differences in performance. Both processors have a GPU clock speed of 300 MHz, but the Intel Core Ultra 3 205 has a higher GPU turbo speed of 1800 MHz, compared to the 1450 MHz turbo of the Intel 300. This suggests that the Intel Core Ultra 3 205's graphics may boost higher under load.

Both processors support DirectX 12, OpenGL 4.5, and OpenCL 3, meaning they offer similar capabilities in terms of graphics APIs. Additionally, both processors can support up to 4 displays, so there is no difference between the two in display support.

Overall, while both offer similar features, the Intel Core Ultra 3 205's GPU turbo speed of 1800 MHz is notably higher than the Intel 300's 1450 MHz, which could lead to a better graphics performance in certain scenarios.

Memory:
RAM speed (max) 4800 MHz 6400 MHz
DDR memory version 5 5
memory channels 2 2
maximum memory amount 192GB 192GB
Supports ECC memory

Both the Intel 300 and Intel Core Ultra 3 205 feature DDR5 memory, with each processor supporting a maximum memory speed of 4800 MHz and 6400 MHz, respectively. The Intel Core Ultra 3 205 has a higher RAM speed, which may lead to better overall memory performance under certain workloads.

Both processors have 2 memory channels and support a maximum memory amount of 192GB, so there is no difference between them in terms of memory capacity or the number of channels.

Neither processor supports ECC (Error-Correcting Code) memory, meaning neither is designed to detect and correct internal data corruption in memory, a feature that is typically important in servers or critical systems.

Features:
instruction sets MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, SSE 4.2 MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, SSE 4.2
Has NX bit

The Intel 300 and Intel Core Ultra 3 205 share identical instruction sets, which include MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2. These instruction sets enable both processors to handle a wide range of modern workloads efficiently, from multimedia processing to cryptography and parallel computing.

Both processors also have the NX bit feature enabled, which helps protect against certain types of malware by preventing code from executing in certain areas of memory.

In summary, the Intel 300 and Intel Core Ultra 3 205 are very similar in terms of features, with identical instruction sets and the NX bit support in both products.

Comparison Summary & Verdict

After reviewing all available specifications, the two processors serve clearly distinct audiences. The Intel 300, with its 46W TDP and LGA 1700 socket, is a practical choice for users on existing compatible platforms who need a power-efficient desktop chip for everyday computing tasks. On the other hand, the Intel Core Ultra 3 205 pulls ahead in nearly every performance metric: it offers a 3 nm semiconductor process, 8 threads versus 4, a 4.9 GHz turbo clock, a substantially larger 16 MB L2 cache, and faster 6400 MHz RAM support, making it far better suited for users who demand more from their desktop system. Its big.LITTLE architecture also adds scheduling intelligence for balancing performance and efficiency workloads. Choose the Intel 300 for budget-conscious or platform-constrained builds; choose the Intel Core Ultra 3 205 for a modern, higher-performance desktop experience.
