What is the difference between the 5800XM and the 5800i What is the lowest price now

One is no 3G at the beginning, and the other is 3G at the back, which is faster than the previous one, and the previous estimate is no longer out. There is no WLAN for licensed goods, **ranging from 1100 to 1700, the screen is a resistive screen, not multi-touch, of course, it is not as easy to use as Apple. The Symbian V5 system is said to be slowly deprecated and eventually come to an end.

For licensed: 5800-XM original function 5800-i: add 3G function 5800-W: add 3G + wifi.

The XM, I series of licensed products have been discontinued, and I don't know.

The 5800-W configuration has shrunk severely, compared to the XM series, the headset has no wire control, and the memory card has shrunk from 8G to 4G.

For parallel goods: 5800-XM: 3G + wireless Internet is 100 200 cheaper than licensed XM

**On 5800xm, the cheapest 1500 bar on the phone**Buy 1800+.

Now it is basically impossible to buy licensed 5800xm

You 5800 will know the difference between the various versions, and licensed goods are of course the antonyms of parallel imports, that is, genuine technical support. I bought a 5800w licensed product last year, 1400, and now it is estimated to be about 1200, it is recommended that you buy it online, cheap. At least 1800 in physical stores.

As a touchscreen machine that Nokia focuses on, of course it is easy to use.

Graphics card 5800x** is generally higher than 5600x, if due to the model, there are** similar 5600x and 5800x, of course, it is recommended to buy 5800x, the performance is better.

5800X is known as the strongest game U,In the test,The default PBO5000 series is also the highest 5800X frequency run,There are still some performance advantages,And 8 nuclear wars in the future。

5600X and 5800X game performance evaluation comparison,You will find that these two CPUs can't pull the distance at all in terms of game performance,At most one frame of hanging,Because they are all zen3 architecture,The performance gap is not big,There is no gap in single-core performance,The main thing is that 5800X has 2 more cores and 4 threads,But the game party basically can't use it。

At present, for game performance requirements, CPU performance is excessive, and the performance of graphics cards is not excessive, and the performance of your graphics card can give you as many frames as possible, and at present, few games can eat up 6T12C specifications of CPU.

How to choose a graphics card:

The mainstream graphics card manufacturers are only NVIDIA and AMD, and some ATI was acquired by AMD. Therefore, the graphics cards on the market are now referred to as N cards and A cards, and various jokes about N cards and A cards are circulating on the Internet.

To put it simply, the N card has high efficiency and high power consumption; The theoretical efficiency of A card is high, but the actual efficiency is not as good as that of N card, and the power consumption is low. Therefore, there is a saying in the market that N card is chosen for games, and A cards are selected for work.

Two things to keep in mind:

1. Many online and offline merchants will boast that their graphics cards have a large video memory capacity and are good graphics cards. In fact, this is completely misleading, the video memory capacity is equivalent to a parking lot, if the speed of the car parked in and the car out is very slow, then it is useless to have such a large space.

2. Merchants with advanced points will boast that their graphics cards are wide and large, and the graphics cards are good. This is also wrong. The graphics card depends on the bandwidth.

Graphics card bandwidth = frequency * bit width. The bandwidth of the graphics card is equivalent to the number of vehicles entering and exiting the parking lot per unit time, the width is equivalent to the size of the road surface in the parking lot, and the frequency is equivalent to the speed of driving. Therefore, when looking at the graphics card, you must not only look at the bit width, but also the bandwidth.

The differences between 5800x3d and 5800x are as follows:

1. The cache is increased to 96MB.

The capacity of the L3 cache at 5800x3d is increased to 96MB (32MB for 5800x), but it is still only 16-way, so the additional capacity does not increase the bandwidth of the L3 cache, but increasing the capacity can increase the cache hit ratio, so that the kernel can reduce the frequency of calling data from memory, and the latency of the L3 cache is much lower than that of memory, which can reduce the wait latency of the kernel, which will bring significant performance improvement in workloads dominated by random data streams such as games.

2. The core frequency is reduced.

The number of cores in 5800x3d is the same as that of 5800x, which is 8 cores and 16 threads, but the frequency is lower, and its base frequency, the base frequency of the boost frequency is, and the boost frequency is.

3. Overclocking performance is not as good as 5800x.

The Ryzen 75800X3D does not provide the same voltage and frequency scaling as them, and AMD has maximized the frequency of the Ryzen 7 5800X3D when it leaves the factory, so the Ryzen 75800X3D does not unlock the CPU voltage and frequency adjustment, and there are no PBO related options in the BIOS. However, memory and if bus overclocking is still open, and gamers can still get performance gains by increasing the memory and if bus clocks.
