Recently, the first reviews of new generation AMD mobile processors appeared on the Web. To be more precise, mostly Ryzen 9 6900HS. And although there were several reviews, they were all far from the most voluminous. Now we have a more holistic view of the new lineup as we have a big look at the more affordable Ryzen 5 6600H and Ryzen 7 6800H. True, the emphasis in the review is on the iGPU.
First, let’s recall that the Ryzen 5 6600H has six cores with frequencies of 3.3-4.5 GHz and a Radeon 660M GPU with 384 stream processors. Ryzen 7 6800H already has eight cores with frequencies of 3.2-4.7 GHz and a Radeon 680M graphics core with 512 stream processors.
If we are talking about the performance of the processor part, there are few tests here. And they do not allow us to draw any conclusion, because in some tests the Ryzen 5 6600H performs at the level of the Core i5-12500H, and the Ryzen 7 6800H competes with the Core i7-12700H, in some tests AMD processors are noticeably faster, and in some, on the contrary, Intel innovations are confidently ahead.
As for the GPU, everything is clearer here. To begin with, you can evaluate how much the speed of RAM affects the performance of the integrated graphics core.
And the performance in general, as we see, is very high. The Radeon 680M is head and shoulders above all competitors in benchmarks, and in games it roughly matches the discrete GeForce MX450. Out of 14 games, Nvidia’s decision is solidly ahead in five. In three, it is noticeably ahead of the iGPU in the Ryzen 7 6800H. In the rest, the cards are approximately equal, and the difference between them in absolute terms does not play a special role. As for the Radeon 660M, this core has half as many stream processors, but even that is enough to easily outperform the core in the Ryzen 9 5900HS and often outperform the iGPU in the Core i7-12700H and Core i5-12500H.
At the same time, interestingly, if the power limit for the Ryzen 5 6600H is increased from 25 to 42 W, then its graphic performance in most games will be identical to the performance of the Radeon 680M in the Ryzen 7 6800H! And this is with half the number of execution units for the GPU. That is, apparently, the potential of the GPU in both cases is severely limited by power limits.
Another interesting test shows that the new AMD APUs experience only a slight drop in performance on battery power, unlike the previous generation of Ryzen. However, for the same Core i5-12500H, this figure is even better.
The Core i9-13900K showed that the new Intel processors will have a lot more cache. But the Ryzen 7 5800X3D is still far away
Despite the fact that Intel Raptor Lake processors should be released only at the very end of the year, they are increasingly appearing in various benchmarks. Today, the top-end Core i9-13900K lit up in the tests.
The software data confirms early rumors that the new CPUs will have much more cache memory. In particular, the Core i9-13900K has a total (L2 and L3) of 68 MB of cache. Apparently, we are talking about 36 MB of L3 cache and 32 MB of L2 cache. To be more precise, only large cores will have L3 cache, and small ones will also have L2.
Presumably, each large Raptor Cove core will have 2MB of L2 cache and 3MB of L3 cache. And each cluster of small cores will have 4 MB and 3 MB, respectively. The new CPUs will have eight large cores, and 16 small ones if we are talking about top models. As a result, Raptor Lake will have 55% more cache than Alder Lake.
However, this will still be comparable only to the Ryzen 5000, which came out a year and a half ago, and Intel processors will still be far from models with 3D V-Cache.
Nvidia graphics cards are much more overpriced than AMD adapters. Comparison of current markups for 3D maps appeared
HardwareUnboxed decided to check out AMD’s recent statement that the company’s cards are more profitable than competitors. It turned out it was true.
If we are talking about the US market, then the markups for Radeon graphics cards are much lower there than for GeForce adapters. The former are on average 5% more expensive than the recommended price, while the latter are already 24% more expensive.
Of course, for each buyer it is more important how overpriced the card he is going to purchase. We can note the Radeon RX 6500 XT, which is on average 3% cheaper than the recommended price. The prices of the RX 6600 XT, RX 6750 XT, RX 6900 XT and RX 6950 XT also look great. But the RX 6800 and RX 6800 XT are respectively 31% and 23% more expensive than the recommended prices, which makes their purchase look pointless.
As for Nvidia cards, the RTX 3090 Ti and RTX 3080 Ti also boast a zero markup, but on the RTX 3060 Ti it is 40%, and in general, junior adapters are greatly overpriced, and the RTX 3050 has risen in price by 5 over the last month. %.
Huawei Watch D is presented in Europe – the first smart watch with a blood pressure monitor
Huawei today introduced the flagship smart watch Huawei Watch D to the international market. The main highlight of the model was the real-time blood pressure measurement function.
The watch originally debuted in China in December 2021 and will now be available in Europe and other regions. The European price is 449 euros.
Huawei Watch D is positioned by the manufacturer as the first smart watch with a built-in blood pressure monitor. According to the manufacturer, Huawei Watch D is six times smaller than conventional blood pressure devices. The watch is equipped with a mini-pump capable of generating pressure up to 40 kPa, which allows you to measure blood pressure up to 230 mmHg. This is equivalent to the range of traditional blood pressure monitors.
At the same time, Huawei Watch D is not only a blood pressure sensor, but also a watch with a pulse measurement function and an ECG sensor module.
In addition, the watch has more than 70 training modes and tracks important physiological parameters of the body. In addition to measuring blood pressure and heart rate, they analyze sleep quality, blood oxygen saturation SpO2, measure skin temperature, stress levels and many other indicators. The watch can work without recharging for up to seven days.
The watch is equipped with a 1.64-inch AMOLED screen with a resolution of 280 x 456 pixels, a 451 mAh battery. Supports NFC, Bluetooth 5.1, GPS. Water protection (IP68) is provided. The watch itself is based on HarmonyOS and can be paired with smartphones based on HarmonyOS 2, Android 6.0 and later, iOS 9.0 and later.
