As we all know, since the AMD Radeon division released a new generation of Polaris graphics card RX 400 series products in June last year, no new products will be available. VEGA is not expected to go public as expected. The focus shifted to Ryzen's AMD finally after the release of the R5 this month. The new .RX 500 series graphics card was released on the 18th of this month. As the rumors say, the RX 500 series is based on an improved version of the RX 400 series and remains at the heart of Polaris. It is also known as the "vest."

We can see that the price of the RX 480 is now around 17XX, but it is already out of stock. Instead, it is the 17XX-19XX level RX 580. Of course there are 2XXX level high frequency 580. The RX 570 also has a frequency of 1340mhz, and the price also replaces the 14XX of the RX 470.
So what is the actual face of the actual RX 580? After all, how should the users of the RX 400 series look at its existence? Let's take a look at its true content.
Unpacking articles:â–¼ Outsourcing of Redeon RX 580 Limited Edition
â–¼ Back package
â–¼ Limited Edition 8GB also has the following OC. Limited Edition Platinum
â–¼ Open the outer package, inside is a layer of leather box
â–¼ A glimpse of RX 580 limited edition real capacity, looks like there is no difference in appearance with RX 480
â–¼RX 580 Platinum Limited Edition Front
â–¼ Length 26cm, width 12.5cm, height 4cm
â–¼ Dual 9CM fan heat exhaust, 3 generations of intelligent start-stop technology, easy to disassemble mode
▼ backplane, using a large area of ​​hollow ventilation
â–¼On the side
â–¼Sapphire's ROG Belief Lamp has six switching modes. But did not see the switch button
â–¼ The BIOS switch button is still above the belief light. The RX 580 limited edition has 1411, 1450mhz dual bios.
â–¼Using 8+6pin power supply strategy
â–¼Downside
â–¼4 heat pipe cooling
â–¼ rear air inlet
â–¼ Rear air outlet/output panel, DVI + HDMI * 2 + DP * 2 output port mode, the outlet port looks like a sapphire S.
The outer packaging of the RX 580 can be said to be different from the RX 480. Only slightly more than 480 judging from the appearance, but its design is closer to technology
â–¼ In terms of product appearance, the RX 580 is also longer than the RX 480.
â–¼ The two sides have the same basic shape, but the RX 580's shroud is bright gray, while the RX 480's black, both use 9CM dual cooling fan, and are easy to remove mode
â–¼ The backplanes on both sides look the same, except that the layout of the two sides has changed, and the RX 580 has more than 480 cooling holes.
â–¼ imported wind to see, RX 580 cooling fins specifications to be tough and RX 480. And the power supply interface of RX 580 is not on this side
â–¼ The output interfaces of both parties are the same and both use the output interface of DVI+DP*2+HDMI*2. What's different is that the RX 580's outlet pattern creates the sapphire's S-shape
The RX 580 is one lap wider than the RX 480. The RX 580 has an open thermal design and the RX 480 has an overall envelope.
The width of the RX 580 is 12.5CM, while the width of the RX 480 is 11.5CM. Both sides are about 4cm high
â–¼ Both sides have Sapphire's belief lamp. There are dual BIOS toggle buttons, but the RX 580's faith light switch mode does not have a button on the video card
â–¼ At the same time RX 580 is 2CM longer than RX 480. And use 8 + 6 pin power supply, positive access to power supply. The RX 480 uses a side power module. If you count the power supply connector, then the actual length of the RX 488 is not much different from the RX 580.
â–¼ There is no difference between the two sides of the back side. The difference is that the RX 580's SN bar code is attached to this side, while the 480 is on the back panel.
â–¼ Clearly can see the size of the four heat pipes of the RX 580. However, the 4 heat sinks of the RX 480 are not obvious
â–¼ Both are wired to power the cooling fan, but the RX 580 is on the front and the RX 480 is on the side.
So judging from the appearance, the RX 580 is slightly larger than the RX 480, and the heat dissipation is better. What is inside?
I have to dismantle some detoxification
â–¼ Start with the screws on the backplane and the screwdriver is ready
â–¼ We first dismantle the five outermost screws and separate the main body from the shroud
â–¼The main body is with the front of the shroud
â–¼Between the shroud and the PCB board there is also a belief light and fan power supply pin connector
â–¼ A Phillips screw is used to fix the air deflector and cooling 9CM fan. It is easy to disassemble.
â–¼ The fan's power supply comes from the 4pin snap-in contact between the shroud and the fan
â–¼ We again disassemble the remaining 9 large screws and separate the heat sink fins from the PCB board.
â–¼ Heat sink fins and cooling base module
â–¼ The cooling base is a large copper block, and the surrounding thermal grease is to heat the memory
â–¼ Heat sink size
â–¼ Vaguely visible there are four heat-dissipating copper tubes. It should be 2 big 2 small
â–¼The PCB board can actually be separated from the thermal backplane. The remaining 3 small screws only fix the other heat sink.
â–¼ The thermal backplane is an aluminum sheet that provides dust protection, cooling, and aesthetics. Of course, the initial role is to prevent PCB board bending
The actual length of the PCB board is 24cm
â–¼ PCB board rear part of the electronic components according to
PCB board front
â–¼RX 580 core and memory layout
â–¼Visible is indeed the core of Polaris

â–¼ bios controller followed by a toggle button, the next pin is the belief lamp power supply
â–¼This is radiator fan power supply
â–¼8+6pin power supply, 6+1+1 phase layout
â–¼Power supply group
The fourth generation of black diamond inductor
â–¼ The shroud, backplane, PCB body, and heat sink are completed in this dismantling.
It can be seen that the RX 580 is indeed an improved version of the RX 480, with slight changes in the appearance of the body, and the PCB has been enhanced. The heat sink has a slightly larger scale.
â–¼ The power supply group has changed to the front because it has reached the standard that most of the normal chassis of 27CM can accommodate.

Fse points RX 480 6083 points RX 580 6409 points
Compared to the RX 480 of 1266-1342mhz, the 1411-1450mhz frequency of the RX 580 is about 100mhz-180mhz higher. The frequency is indeed much higher. At present, from the running point of view, it is about 5%-7%. But what I don't understand a bit is that a friend's water-cooled RX 480 oc is about 1425mhz, and FSE points are already 6500 points. Is RX 580 protected?
▼ donut roast chicken more than 10 minutes to get the information, room temperature 28 °C
It can be seen that in fact donuts do not have a frequency of 1450mhz. It may be a software problem or a protection wall. The maximum temperature is 77 °C. However, fan strategy issues, and not full speed, currently only 37% of the speed, the maximum power supply is 217W
RX 580 Limited Edition Game Test:
(all online FPS games, the actual number of frames may be affected by the network or player operations and decline)
â–¼Battlefield 3:
Test 1080P image quality and 2K image quality respectively, and set the default image quality to "highest"
The average number of frames under 1080P is 97fps and the temperature is up to 74°C. The average number of frames at 2K is 87fps and the maximum temperature is 69°C.
â–¼Battlefield 1:
Test 1080P image quality and 2K image quality separately, and set the default image quality to “highestâ€
Under 1080P, the average number of frames is 92fps and the maximum temperature is 77°C. The average number of frames at 2K is 72fps and the maximum temperature is 76°C. Because it is a 64-person room, in the offensive and defensive battle, many people exhibit smoke bombers and other effects may lead to low frame rates.
â–¼ watch the pioneer:
Test 1080P image quality and 2K image quality respectively, set the default image quality to "Ultra High", 100% render, and turn off the frame rate to synchronize with the monitor.
Under 1080P, the average frame number is 104fps, the maximum temperature is 73°C, the average frame number under 2K quality is 75fps, and the maximum temperature is 73°C. The operation is also extremely smooth, with few visible fluctuations, and almost all of them are presented in intensive attacks.
As for the game performance of the sapphire RX 480, please look at the post I posted last year. I will not repeat the test here.
Power test:
â–¼RX 580 platform standby power consumption about 59.6W
â–¼ RX 580 platform machine GPU press temperature is about 298W
â–¼RX 580 platform CPU + GPU at the same time open the pager standby temperature of about 369W
Appearance: RX 480 is less than RX 580. The former is powered on the side and the latter is powered on the front.
Workmanship: RX 580 work slightly better than RX 480, the former fins better than the latter.
Frequency: RX 580 frequency 1411-1450mhz, RX 480 frequency 1266-1342mhz
Performance: Currently 17.10 drives RX 580 strong RX 480 5%-7% or so
Power supply: The RX 580 is powered by 8+6 pins and is currently measuring up to 217W. RX480 power 8pin, measured up to about 150W.
to sum up:Correctly look at the RX 580, which is an enhanced version of the RX 480. High frequency, while increasing the power of the OC 6pin. Has reached more than 220 W of power supply. There is a 5%-7% increase, but for the user of RX 480 itself, the current driver protection is not very obvious. If the users of RX 480 use water cooling, the OC with good constitution may also achieve this effect. The RX 580 is just a basic frequency enhancement, with a strong heat sink and a better OC constitution. Users of the RX 480 can be detoxified without having to upgrade. It's just a normal product update enhancement. Users who have not upgraded their intentions do not belong to the replacement level. In fact, I prefer the RX 480's body design. Can only say RX 500 series came out, if the next new release, there is no VEGA, I'm afraid the player is very disappointed.
Lithium Ion Battery For Electric Golf Cart
Advantages of Lithium Golf Batteries
Lithium golf batteries (or LiFePO4 batteries) have been around for a while now on electric golf buggies, but until recently have been quite expensive. Most brands now including MGI Golf, Autocaddy, Motocaddy and Powakaddy come standard with lithium ion batteries. But not only can you get a lithium battery for a new golf buggy, there are suppliers providing them for older buggies by running on the same voltage as a lead acid battery.
Below is a breakdown of the advantages of a lithium golf battery over their lead acid counterparts:
Greater life expectancy
The main advantage of a lithium battery is the life expectancy. Whilst a lead acid battery will last around 300 cycles, a lithium battery can last up to 5000 cycles, meaning over the life of the battery a lithium is more cost effect per round of golf. Lithium batteries are maintenance free and have the benefit of a control board built in, thus ensuring worry free golfing.
Light weight
Another advantage is in the weight of the battery. A lithium battery weights on average 5 times less than a similar amp-hour lead acid battery. This makes it easier to lift making it easier to transport to other golf courses. The lighter weight also puts less strain on your buggy and therefore less wear and tear over time. This will improve the life of your buggy and mean less repairs will be required.
Short Charge Times
Charging times are also reduced when using lithium batteries over lead acid. Whilst it can take over 8 hours to charge a lead acid battery, a lithium battery can be fully charged in less than 3 hours. Lithium batteries are also able to be left off charge for longer periods of time compared to a lead acid battery. Once fully charged your lithium battery can be left off charge for up to 3 months before any damage occurs, whilst a lead acid battery will start to sulphide within 3 weeks.
Low Maintenance
Lithium batteries (Li-Ion batteries) require less maintenance than most forms of batteries. Other batteries, such a lead acid, require a periodic discharge to maintain the battery memory. This is not required for Lithium batteries, which can be left off charge for up to 3 months (once fully charged).
Lithium batteries also do not require topping up, like older forms of lead acid batteries. This means there is less maintenance required and less that can go wrong.
So there you have it, a lithium golf battery will not only last longer than a lead acid battery, but will save you time and money over its life.
