RADEON RX 460 – RX 480
Generally speaking, the new AMD graphics cards have been released in typical AMD fashion – slightly weaker platform at a slightly cheaper price than its competitors. The lead of the new RX lineup (up to the RX 490 – which has left the label) is the Radeon RX 480.
The Radeon RX 480 is the first graphics card build around AMD’s 14nm Polaris 10 GPU, the most modern generation of graphics Core Next Architecture (GCN). The kernel operates at a declared frequency of 1120 MHz, and can be dispersed to 1266 MHz. The video card is equipped with high-speed memory – GDDR5, with a minimum clock frequency of 1750 MHz. The memory bus is 256 bits, which is quite normal for the price that the card is offered. The overall performance is estimated at 5.8 teraflops, and it supports DirectX 12 as well.
Despite the obvious advantages, the main difference between the new nuclei today the Radeon RX 480 is produced by using the latest FinFET 14nm processor technology, while about 5 years ago the video cards were released on 28nm. Further, in regards to power consumption, although it claims 150 watts, without overclocking, the average load card “eats” about 20% less.
The Radeon RX 470 can easily be considered the “cheaper version” of the RX 480. You’re probably thinking, “then why not move on to the RX 460?” The answer is quite simple; this card uses the same kernel as the older version – 14nm Polaris 10 GPU. The working clock frequency here is reduced to 926 MHz, thus, with acceleration it is possible to get 1206 MHz.
The memory is the same – GDDR5, but it has a little bit less clock frequency-1650 MHz. Nonetheless, same as the older version, memory interface is not cut and is 256 bits. As a result, RX 470 produces at a peak load of approximately 4.9 teraflops. Of course, this is less than the RX 480, but generally speaking, it’s comparable. The average power consumption here is stated as 120 watts, in reality the value is slightly less. Due to reduced performance, such a video card can be advised when used in Full HD resolution.
The Radeon RX 460 is definitely the “weak link” of the lineup. Despite the fact that it also supports DirectX 12 and other software, this video card contains the Polaris 11. Similar to the other cards, the memory is GDDR5 with a frequency of 1750 MHz, while the size of the data bus is up to 128 bits. The clock frequency of the GPU is 1090 MHz (1200 with acceleration). The power consumption is up to 75 watts, which is quite a bit for the video card. A quick note that may be of interest is that out of all 3 of the RX cards, the RX 460 is the only one that doesn’t have an additional power connector. Unfortunately, the various downgrades of the “younger brother” results in a modest 2.2 teraflops, -more than double the difference of the RX 470. Logically, this solution is more suitable for network games with not the most difficult graphics.
Let’s start with the Nvidia GeForce GTX 1080. Out of the GeForce line, the 1080 is the latest model, as evidenced by its name. It has the Pascal architecture and the new 16-nanometer process FinFET, which, for a very long time (almost 5 years), was expected to replace the frankly outdated 28nm. However, the problem was that it was not possible to achieve high quality of the final product in the transition process (20 nm)-thus, the existing production capacities of the contractor TSMC were sharpened to produce only small chips. Simply put, almost double sprout in process provides either a reduction of power consumption by 70%, or an increase of clock frequencies by 65%.
The GTX 1080 graphics card is based on the new gp104 core, and is the most powerful solution in the market-driven lineup. Relative to its predecessor 980, the 1080 logically increased in clock frequencies almost twice: 1607 MHz in normal mode compared to 1126, and regarding acceleration-1733 MHz against 1216. The bus here is 256-bit, and the memory is even faster than that of AMD: now it is 8 GB GDDR5x with a frequency of 1250 MHz. By the way, this type of memory is currently unique in the market, as other solutions of this manufacturer GDDR5x have not yet been received. The main difference from GDDR5 is the increased throughput: 320 GB/s versus 256. Power consumption here is up to 180 watts.
The younger sibling of the 1080 is the GTX 1070. There are multiple similarities such as the gp104 on Pascal and 16-nanometer centrifugal. The frequency of the GPU is 1506 MHz, while the acceleration is 1683 MHz. Memory bus 256-bit, volume-8 GB. This is something that should be sufficient for a few years. As I have already noted, the memory type is GDDR5, the prefix “X” has not been received.
Power consumption is slightly more modest-up to 150 watts. Interestingly, this card is already noticeably closer in performance to AMD Radeon RX 480 and gives out about 6.5 teraflops. This figure is still higher than the AMD solution, but they are at least comparable. As with the Radeon RX 460, this video card was not only the weakest of the bunch, but also to a certain extent has disadvantaged characteristics. In particular, the weaker kernel gp106 with the main working frequency 1506 MHz and 1708-at acceleration. The memory is still type GDDR5, but the bus is already 192-bit, and the amount of memory is 6 GB. Energy consumption is reasonably lower — 120 watts. The performance is typed about 4 teraflops.
COMPARISON OF THE LINES AMD RADEON RX 460-480 AND NVIDIA GEFORCE 1060-1080
So, let’s end the discussion of the AMD and NVIDIA graphics cards by crossing our “T’s” and dotting our “I’s.” As you may have probably noticed, our goal was not to write a detailed overview of each video card, so we intentionally omitted many details of the universal processors and texture blocks, connectors, and the technical solutions used for computing.
The technical enthusiast in any case has already probably made up his mind of what he wanted to buy, our goal is simple – to provide an explanation for people who are not tech savvy. To make your lives easier we will explain the most significant indications such as overall performance and prices of video cards.
It’s clear as day, that when comparing the two new lines from AMD and Nvidia, the GeForce GTX 1080 video card is currently unparalleled at the moment and reigns undivided at the top of the technological pyramid. If you compare this video card with the previous generation from AMD, Radeon R9 Fury X or Radeon R9 390x, the GTX 1080 will rule above them. Nonetheless, I’ll be honest with you, it’s worth acknowledging that for certain types of graphics (for example, fur rendering) solutions- AMD traditionally win.
It is also clear that the more expensive Nvidia GeForce GTX 1060 is clearly inferior to the performance of AMD Radeon RX 470 and 480, especially if viewed as the most economical option to buy a 4GB memory card. Moreover, when comparing performance indicators between the Nvidia GeForce GTX 1070 and AMD Radeon RX 480, the former performance 1.5 times more!
So, AMD is aiming to take away some market share from the Green Giant –Nvidia, which currently dominates the market. Unfortunately for us consumers, its dominance results in higher prices for Nvidia products – it wouldn’t make sense for Nvidia to reduce its price because even with lower pricing, AMD has to fight to its market share.
