Hello, everyone. Lin Fei has come to answer the above questions. Many people don't know about Sapphire 4850 and Sapphire 4850. Now let's take a look!

Introduction: in our daily life, we often use a lot of electronic products, many friends who love computers should also often come into contact with graphics cards! Now the domestic graphics card market, it can be said that the number of brands is really dazzling, especially for people who are not familiar with it. When buying a graphics card, there is no way to start. Among them, there is a brand of graphics card called Sapphire, which has a good reputation. Today, Benshaw will introduce the evaluation and quotation of Sapphire 4830.

Sapphire 4830 assessment

New overseas version of sapphire) HD4830 continues the exquisite design of sapphires on the box, and its luster has felt the brand flavor of the high-end front line. In appearance, the graphics card is similar to the non-public version of the HD4850/HD4830 series that sapphire has always used. After all, it directly uses HD4850 PCB and surrounding materials, Lake Blue PCB decorated with eye radiator, very unique.

In terms of core, the new overseas version of Sapphire HD4830 adopts the latest batch of RV770LE cores, completely inherits the excellent core architecture of HD4800 series, and has near-perfect AA/AF HD performance and a series of advanced technologies such as Direct X 10.1, Powerplay, UVD2 and so on. When 640 processes and memory streams are running at the default frequency of 575/1800MHz, 3D performance is about 85% of HD4850, but

Blue's exclusive "Typhoon Eye" cooling system, HD4850/30 regular users know that this copper core aluminum extrusion process of the open radiator is very practical, the heat dissipation capacity is even comparable to the classic Simin VF900. And the typhoon eye used in the overseas version of HD4830 is newly upgraded to the 4PIN PWM interface, which makes the speed and temperature control more intelligent, thus achieving the quietest experience.

In terms of power design, the overseas version of Lambao HD4830 continues to optimize the PCB design on the basis of the previous Lambao RV770 non-public version. In terms of materials, a 21-phase high-efficiency independent power supply system is adopted, with uP6201 PWM chip as the core, 8 Infineon high-speed Mosfet (all in PG-TDSON-8 package, 2 BSC042N03LS and 2 BSC120N03LS per phase), plus fully shielded inductors and all-solid-state capacitors.

In terms of memory, Sapphire also uses 8 16X32 Qimengda 1.0ns GDDR3 memory to form a strong 512M/256bit memory lineup. Now the default factory frequency of the overseas version of sapphire HD4830 is only 575/1800MHz, which is much lower than the 2000MHz which can run stably without overclocking relative to the 1.0ns standard. This product leaves a lot of room for free performance improvement.

Sapphire 4830 quotation

On the back of the blue graphics card, you can always see the unusual fine workmanship of front-line manufacturers. This overseas version of HD4830 is no exception. Players in the purchase of graphics cards, might as well compare the same price. Naturally, we have a deeper understanding of "goods for every penny" and "products of front-line manufacturers". I believe that at the current price of 599, the workmanship of blue graphics cards is difficult to be surpassed by other brands. (price source network, for reference only)

All right, the above content is the relevant evaluation and quotation of Sapphire 4830 introduced by Bian Xiao! I believe that everyone must have their own understanding of this memory graphics card! There are many kinds of graphics cards on the market now. Sapphire 4830 is superior to other brands in terms of appearance and performance, and its design technology is advanced. Benshaw suggests you buy it. Of course, you can also compare several graphics cards before deciding how to choose.

At the end of this article, I hope it will be helpful to you.
