Recently there have been rumors or broke the news on Intel and AMD jointly build the ultimate product - Kaby Lake-G, this really came, based on Intel Core CPU and AMD Vega nuclear display, and integrated HBM2 memory processor, in This year's Las Vegas CES2018 Pavilion, Intel officially unveiled this Kaby Lake-G's mysterious mask.
Have not remember how long before the thing, from the Beastmaster has not done before this line, there has been someone looking forward to Intel & AMD marriage of the ultimate product.
After all, AMD APU's nuclear GPU was enough to power up until 2017, but the CPU was a bit overwhelmed, while Intel's short board was just on the GPU. The absolute performance and power consumption of the CPU were far better than that of the AMD ... so we look forward to this The product is not without reason ...
First, to a great extent to save valuable space in the notebook
The left side of the PCB module is Kaby Lake-G's body, I believe recent attention to DIY players have seen this figure, but the technical details of which must see this technical article.
The chip can be seen in the figure were packaged a total of three modules (covered by a silver shell), from left to right are HBM2 memory, AMD Vega M series of GPUs and 8 generations of Core CPU.
This chip is currently only used in notebooks and mini NUC host.
1, the bridge mode and package thickness:
The PCIe 3.0 x 8-channel connection between the GPU and the CPU, although it is × 8, is more than enough for the mobile Vega, which will be analyzed later on.
Package thickness of only 1.7mm, the number of pins only half the original product , The benefit is to some extent reduce the thickness of the notebook, motherboard design and OEM manufacturers more difficult, and this is precisely the scope of this chip accurate positioning.
2, the overall area dropped significantly
Due to the HBM2 memory stacking technology, less than a single GDDR5 memory space can accommodate 4GB of HBM2 memory, and the memory bandwidth is larger and faster.
So compared to the original way, It saves 1900mm? Of space, and further savings in the notebook's valuable interior space.
In addition, as the three close together, so only a little larger fan, you can A fan can hold down both modules , Compared to the previous CPU + independent GPU way, but also save a fan space for the notebook ...
As mentioned above, this Kaby Lake-G saves internal space in three dimensions, plus the combination of Vega M and HBM2, so it's easy to see where it's positioned as an ultra- Is both a game performance and lightweight game book.
Second, dynamic power control
Here's a new Intel technology that dynamically distributes the load and power consumption of the GPU and CPU so that they do not exceed the preset total power consumption, while the Kaby Lake-G series will have 65W and 100W.
For example, when dealing with video, in fact, the main call will be the CPU resources, so this state the chip will be allocated to the CPU power, leaving the GPU into a very low load state, and when the GPU needs to be high Frequency operation, it will reduce the CPU power consumption, so that the battery more efficiently allocated.
In the past when the CPU + discrete graphics is not able to achieve this dynamic power control. This benefit is to improve laptop life, improve the effective use of power.
After using the above Intel Dynamic Tuning technology, can make the notebook's energy consumption ratio increased, the effect is to be able to save 17.5W power consumption under the premise of energy consumption increased by 18%, that is, the power can be used in a more correct Place.
Third, the CPU part of the eight generations of the original U series, nuclear still
Kaby Lake-G's CPU is directly applied to the original eight generations of mobile processors, such as i7-8550U, coupled with the Vega GPU becomes i7-8809G, so the original nuclear significant UHD620 is still there.
The benefits of retaining the HD630, in many cases can directly call the UHD630 core display operation, both efficient and power saving, such as Intel exclusive HEVC, 4K 60 frames and so on video decoding and encoding.
Fourth, CPU and GPU parameters of the size and composition
Parameter interpretation: A look at the cache, the core number and native GPU nuclear show have not changed, but slightly increased the frequency, I know that i7-8809G is based i7-8550U build.
With a total TDP of up to 100W and Intel Dynamic Tuning technology booting, the CPU part consumes much more power than 15W when necessary, so the base frequency is designed to be 3.1GHz.
There are also based on i5-8350U and other i7 revision, look at the map to know.This series contains a total of four CPUs and two GPUs, permutations and combinations up to 4 × 2 = 8 combinations, depends on OEM notebook how to choose how to match the brand.
Also see, there are two versions of Vega, one is called Radeon RX Vega M GH, one is called Radeon RX Vega M GL, apparently the M word is that mobile version, G is said to belong to the Kaby Lake-G series of products, and later Will be listed on the Vega APU phase distinction, H and L, respectively, on behalf of high power consumption and low power consumption.
So the GH suffix will be 100W TDP, while the GL suffix will be 65W.
Fifth, some test items ran points war GTX1060
GH suffix, that is, with a high version of the Vega, 3DMARK 11, and three A card itself is relatively advantageous VULCAN, DX12 game which are running stronger than i7-7700HQ + GTX1060 Max-Q combination.
Need to know i7-7700HQ itself is stronger than the i7-8550U, so that it can slightly better than the GTX1060, the Vega M GH's performance has been bright enough, Need to know i7-7700HQ + GTX1060 combination of power consumption is far more than 100W.
However, due to run the game itself A card has a certain advantage, so make a discount, So that the performance of Vega M GH GTX1050Ti is not a little pressure at all.
As for the low version of the Vega M GL comparison is the GTX1050, you can see it is a lot stronger than the GTX1050 or large, so that with the high version of the Vega M GH GTX1050Ti performance than there is evidence.
Here, we come back to the above PCIe 3.0 × 8 channel problem, alone was GTX1050Ti and GTX1050 gold finger slot design is PCIe 3.0 × 8 (do not believe you just open a Jingdong search a GTX1050Ti look at the picture Gold finger to understand).
So, the connection between i7 and Vega with PCIe 3.0 is enough.
Sixth, the ultimate goal is to create enough thin but strong enough to play this thin game
All the above-mentioned new technologies actually start from the concepts of 'lightness' and 'thinness'
Lower package thickness, more area savings but powerful HBM2 memory, more dynamic dynamic power technology, higher energy consumption ratio, called black technology is not an exaggeration.
Recall that those with the i7HQ + GTX1050Ti this thick game there, if you happen to have some hands, it is clear. (Hewlett-Packard, Dell, Lenovo, Divine, ACER and so on the brand has such product)
But now Kaby Lake-G, Has more than GTX1050Ti gaming performance, but the thickness can be controlled at 17mm , Not yet applause?
Seven, time to market
Product circuit diagram can see the release time is ... Beastmaster sent this moment, US time at January 6, 2018 at 6 pm.
Time to market depends on Dell and Hewlett-Packard, the most advanced OEM customers, anyway, BM has received news that they will release the corresponding notebook CES2018.
As for the price, In view of the use of HBM2 memory , As well as performance, energy consumption is much higher than the GTX1050Ti, thickness and thinner, with Intel's consistent pricing strategy, the price will be more expensive than the i7 GTX1050Ti game, as to how much you know after two days. ..
Given its greatness, Beastmaster estimates it will be right The current GTX1050Ti level of the game have a certain impact , NVIDIA may slightly reduce the GTX1060 and below the GPU chip prices to improve the competitiveness of this level of the game; and some for the pursuit of performance and degree of thin users have a more suitable for their new choice.
As Kaby Lake-G really can push a lot of success, it depends on the production capacity of HBM2 memory and Kaby Lake-G final game pricing.
