Intel Efficiency Cores and Performance Cores Explained
Intel's approach to CPU core design involves two distinct types of cores: Performance Cores (P-cores) and Efficiency Cores (E-cores). This differentiation is important to understand when comparing Intel CPUs to AMD's, where all cores are of the same type — full-powered processing units.
The clever aspect of Intel's design is that it assigns background tasks to the E-cores. For instance, the numerous open Chrome tabs, your Spotify music player, and monitoring applications like NZXT Cam would typically run on these efficiency cores.
This strategy alleviates the load from the P-cores, allowing them to focus on more demanding tasks such as video editing or gaming. By offloading to E-cores, the P-cores are free to deliver optimal performance where it counts.
However, it's crucial to note that Intel's 16-core processor isn't necessarily twice as fast as AMD’s 8-core options. The E-cores are incredibly useful for multitasking and efficiency, but they don't pack the same punch as AMD's uniform high-powered cores, or even Intel’s P-cores.
This means that in tasks where raw power from every core is required, the performance may not scale linearly with the number of cores due to the mix of core types. Understanding this distinction is key when evaluating the performance expectations of Intel's hybrid architecture in comparison to AMD's offerings.
In-Depth Comparison: Ryzen 7800X3D vs. i7-13700K
In Gaming tests performed by Hardware Unboxed we can clearly see the differences between the Ryzen 7800X3D and Intel I7-13700K. Here we have the testing bench and some of the results explained.
For the testing bench, the AMD Ryzen 7800X 3D was installed on a Gigabyte X670 Aorus Master motherboard using the latest F11c BIOS revision. DDR5 MHz 6000CL30 memory was utilized for this setup.
On the other hand, the Intel Core i7 13700K was tested using an MSI MPG Z790 Carbon Wi-Fi motherboard, DDR5 7200 MHz memory. Capitalizing on the Intel CPU's support for higher-clocked memory to give it every advantage possible.
For graphics, the Asus ROG Strix RTX 4090 OC Edition was employed, with benchmarks conducted at 1080P, 1440P, and 4K resolutions.
In "Hogwarts Legacy," the Core i7 13700K demonstrated impressive performance, delivering 12% more performance than the 7700 at 1080p.
However, the real competition here was the Ryzen 7 7800X 3D, which outperformed by 8%, averaging 128 FPS. This lead was consistent at 1440P, and it was only at 4K resolution that the 13700K and 7800X 3D ended up closely matched.
Hogwarts Legacy with Ray Tracing
When enabling Ray Tracing in "Hogwarts Legacy," which increases the GPU bottleneck, the 7800X 3D still maintained a lead, being 10% faster at 1080p. This advantage was reduced to just 4% at 1440P, and at 4K, the performance difference was virtually negligible.
Call of Duty: Modern Warfare II
In "Call of Duty: Modern Warfare II," the performance across all tested CPUs is relatively similar. The AMD Ryzen 7800X 3D manages to edge out with a slight advantage, being 10% faster than the Intel Core i7 3700K at 1080p.
This performance lead is slightly reduced at 1440p, with the 7800X 3D being 6% faster. However, by the time the resolution is increased to 4K, the game becomes largely GPU-bound, resulting in the CPU differences having a minimal impact on the overall performance.
In "Cyberpunk 2077," we encounter the first instance where Intel's 13700K outperforms the 7800X 3D. At 1080p resolution, the 13700K delivers 3% more performance.
However, this margin diminishes to zero at 1440p, and a similar trend is observed at 4K resolution, where the difference in performance between these CPUs becomes negligible.
Cyberpunk 2077 with Ray Tracing
With Ray Tracing enabled in "Cyberpunk 2077," the performance of the 13700K and the 7800X 3D is evenly matched, resulting in a tie.
In this scenario, both CPUs exhibit slightly better performance than the standard Ryzen 7 700, and they outperform the 5800X 3D notably, especially when comparing the one percent lows.
Star Wars Jedi: Survivor
In "Star Wars Jedi: Survivor," the AMD Ryzen 7800X 3D shines, outperforming the Intel Core i7 13700K significantly. At 1080p, the AMD chip was 21% faster than the Intel. This gap shows AMD's strength in CPU-heavy tasks.
The 13700K, though, did beat the older Ryzen 7 700 by 22%. This shows Intel's progress. AMD's 7800X 3D benefits greatly from its 3D V-Cache tech, enhancing its efficiency.
But, as resolution goes up, the difference shrinks. At 1440p, AMD's lead drops to 5%. At 4K, CPU choice matters less as the game relies more on the GPU. At these high resolutions, the GPU's role in performance becomes more critical.
We see the same behavior in other games like “Spiderman Remastered”, “F1 22”, “Shadow of the Tomb Raider” and “Tom Clancy's Rainbow Six Siege”.
In the last one we can see a difference of 27% at 1080p with staggering 548 AVG FPS with the Intel i7-13700K and 649 AVG FPS for the AMD's 7800X 3D.
In other games the results showed virtually no difference in performance as these Games don’t challenge current flagship CPUs capabilities. This is true for:
- Fornite DX11 and 12.
- The Last of Us Part 1.
- Halo Infinite.
- Hitman 3.
- The Callisto Protocol.
