#Intel burn test ryzen windows
With a heterogenous core architecture combined with improvements to OS scheduling in Windows 11, Alder Lake has the advantage of being able to delegate tasks to the E cores or P cores as the case may be in a more efficient manner. Intel Alder Lake, however, is the one to watch out for. Moreover, AMD's presentation did indicate 5 GHz designs at 35 W itself with the Ryzen 9 6980HS and at 45 W+ with the Ryzen 9 6980HX. AMD did say that Zen 3+ offers additional sleep states and improved power management leading to up to 24 hours of video playback time on battery, but this remains to be evaluated in real-world testing.
The AMD Ryzen 6000 Zen 3+ chips are based on the TSMC 6 nm process but largely carry forward the architectural improvements we saw with Ryzen 5000. Intel's first tryst with 10 nm has definitely been meritorious, but aspects related to power efficiency seem to have taken a hit. Overall, it looks like AMD's investments into improving the power consumption with Zen 3 Cezanne have paid off well. You can see individual Cinebench R15 multi power consumption patterns for all the tested laptops in the below graph. The Ryzen 5 5600H leads the Core i5-11400H by 34% as well - this is despite the Core i5-11400H operating at a lower 2.7 GHz base clock at 45 W compared to the Ryzen 5 5600H's 3.3 GHz. For instance, we see the Ryzen 9 5900HX to be 32% more power-efficient than the Core i5-11300H despite sporting twice the core and thread counts and higher frequencies. The gap further widens with the Core i9-11900H, which lags by 37% compared to both the Ryzen 9 5900HX and the Ryzen 7 5800H.Įven the mid-range hexa-core Tiger Lake-H Core i5-11400H and the quad-core Core i5-11300H fare bad when it comes to overall power efficiency. As seen in the chart above, we find that AMD Cezanne Zen 3 processors in general are able to achieve higher performance per Watt compared to corresponding Intel offerings.Īt the top-end, we find the Ryzen 9 5900HX to be about 29% more efficient than the Tiger Lake-H flagship, the Core i9-11980HK. While the Tiger Lake-H CPUs do seem to have closed the multi-core gap with AMD Cezanne, things change dramatically when power efficiency figures are taken into account. The Ryzen 5 5600H, however, does have a clear advantage over the Core i5-11400H in multi-core workloads. We see that the Core i9-11900H and the Ryzen 9 5900HS are mostly on par with each other and so are the Core i9-11980HK and the Ryzen 9 5900HX. The chart below shows Cinebench R15 multi-core scores taken in average across all laptops tested for a given processor. This is to ensure that the variations in the internal display specifications do not affect the scores. You can read about individual CPU power consumptions under various loads in each of the dedicated CPU pages linked below.įor a broad perspective in comparing the power efficiency between Intel and AMD laptops, we considered the Cinebench 15 multi-core test running on an external monitor. To test how power-efficient these laptops were overall, we subjected them a variety of tests. Of these 43 were powered by Intel Tiger Lake-H and 30 by AMD Cezanne-H. We had reviewed about 73 laptop designs with 45 W CPUs over the past year. 3D Printing, 5G, Accessory, AI, Alder Lake, AMD, Android, Apple, ARM, Audio, Benchmark, Biotech, Business, Camera, Cannon Lake, Cezanne (Zen 3), Charts, Chinese Tech, Chromebook, Coffee Lake, Comet Lake, Console, Convertible / 2-in-1, Cryptocurrency, Cyberlaw, Deal, Desktop, E-Mobility, Education, Exclusive, Fail, Foldable, Gadget, Galaxy Note, Galaxy S, Gamecheck, Gaming, Geforce, Google Pixel, GPU, How To, Ice Lake, Intel, Intel Evo, Internet of Things (IoT), iOS, iPad, iPad Pro, iPhone, Jasper Lake, Lakefield, Laptop, Launch, Leaks / Rumors, Linux / Unix, List, Lucienne (Zen 2), MacBook, Mini PC, Monitor, MSI, OnePlus, Opinion, Phablet, Radeon, Raptor Lake, Renoir, Review Snippet, Rocket Lake, Ryzen (Zen), Science, Security, Single-Board Computer (SBC), Smart Home, Smartphone, Smartwatch, Software, Storage, Tablet, ThinkPad, Thunderbolt, Tiger Lake, Touchscreen, Ultrabook, Virtual Reality (VR) / Augmented Reality (AR), Wearable, Wi-Fi 7, Windows, Workstation, XPS, Zen 3 (Vermeer), Zen 4
