Before we begin, let's first share some disheartening news for Xianyu users.

Recently, Xianyu announced that it will charge a service fee to all sellers, with the specific guideline being **"a 0.6% basic software service fee will be charged to all sellers (with a maximum of 60 yuan per transaction). At the same time, for sellers who generate more than 10 orders and a cumulative transaction amount of more than 10,000 yuan in the same calendar month, a 1% software service fee will be charged for each transaction exceeding this limit."** A second-hand platform is charging more than Pinduoduo.

Now, let's move on to our main content:

First up, the Tesla C2050 3GB [priced around 100 yuan]

The name is quite impressive, as it bears a resemblance to the 20-series RTX 2050, and it's a well-known brand, Tesla. With nearly 3GB of video memory, it can be said to be worth the 100 yuan price tag. Although it only has one DVI video interface, the most important thing is that the price is very affordable.

However, the reality is not as it seems, and the truth may disappoint you. Upon closer examination of the specifications of the C2050, you can find that its core is even older than my age:From the GTX470 core of 2010. And all specifications are dissimilar. The power consumption is also identical, with a TDP thermal design power of 260w, using an 8+6pin power supply interface, a solid strategic partner of the national power grid, a dark piece of electricity guzzler.

You should know that a GTX750 with similar performance only requires about 70w, and the price is also around 100 yuan, and there are many models of GTX750 that rely solely on the motherboard for power supply, without the need for an external power supply. And this performance is not needed for 3G of video memory in most scenarios. So the C2050 is really outdated and inferior.

Recommendation index: Zero

The second one, AMD FirePro S7150x2 with 16G of video memory [around 200 yuan]

The name sounds impressive. After all, this is a true master with two cores. And the performance of a single core is even stronger than the 1050Ti, which seems more intimidating.

However, this thing also has a lot of drawbacks. The most important one is the cooling issue. It doesn't have a cooling fan, so the temperature is out of control, and it's not easy to modify.

Moreover, the two cores cannot be crossfired, they can only be used for virtualization, multitasking, or mining?Moreover, although this device has a mini DisplayPort video interface, the interface does not support output. It's there, but it might as well not be. It also requires assistance from other integrated graphics or a dedicated graphics card for output.

Recommendation rating: Zero stars (unless you can really make use of its virtualization features)

The third one, P106-90 [around 60 yuan]

It is a genuine mining card, designed specifically for mining purposes, so you don't have to worry about buying a mining card because it will definitely be one. In terms of model, it is the close relative of the P106-100, but the P106-90 is more like the P106-100's direct offspring in terms of performance.

Although the P106-100's specifications are very close to the GTX1060 6G, the P106-90 has a significant difference compared to the GTX1063. The P106-90 not only has half the video memory but also has half the number of stream processors, and the PCI E channel only runs at X4 1.0 speed.

Currently, it is priced at only about 50 to 60 yuan, with performance roughly equivalent to the 1050 to 1050Ti. It's a graphics card for fun and amusement.

It does not have display output interfaces, and it also requires assistance from integrated graphics or another dedicated graphics card for output.Recommendation Index: ★★☆☆☆

The fourth model, Tesla M40 12G [around 250 yuan]

Although it has better performance than the P4, the M40 is significantly cheaper than the P4, which is priced around 600 yuan. This statement may seem contradictory, but it reflects the current situation with the M40 and P4.

Likewise, it has no fan and no video output, and requires a strong level of patience and hands-on ability from the user. However, it is precisely because the M40 lacks a fan and video output that its price is so attractive.

Despite its low price, the M40 can achieve benchmark scores on Master Lu that surpass those of the GTX 980, making it a desirable option for gamers with limited budgets.

Recommendation Index: ★★☆☆☆Clause 5, the i7 8709G's integrated graphics are [debatable].

Although the 8709G only has four cores and eight threads, a relic from the past, the integrated graphics part of the 8709G is hailed as the strongest integrated graphics of its time, with performance on par with the 1050TI. Nowadays, the whole machine with 8+256G of memory is priced at 800 yuan, which is quite a sigh.
