The new Navi GPU has finally arrived and is on the shelves with impressive performance numbers. The new series currently includes RX 5700 XT, Rx 5700 and RX 5700 XT 50th Anniversary Editions, but now rumors that 5600, 5800 and even 5900 cards may be in development are spreading.
We know that the three cards that exist represent the new RDNA GPU architecture and will be the first card designed to replace GCN since 2012. Dr. Lisa Su said that the new architecture is a new look for graphics cards, and its GPU will be redefined in the future, just like Zen did with its CPU lineup. Due to the new CPU released on July 7, AMD
has recently made headlines. The new Ryzen chip series has already conquered the market, and it looks like it has pulled Intel out of the CPU hierarchy for the first time in decades. If the Navi series, also launched on July 7th, looks like its new CPU product line, then look forward to something great in AMD’s GPU closet.
Having said that, we already know a lot about the new Navi GPU and the features it provides. In the next article, we will discuss everything we know about Navi and how the new card will affect consumers who want to build a gaming platform in today's market.
Let’s take a closer look at the recently released RX 5700 XT, RX 5700 XT 50th Anniversary Edition and RX 5700. The
RX 5700 XT 50th Anniversary Edition, or what we call 5700 XTAE, is the most powerful of the three graphics cards released under the new Navi lineup. Like all Navi cards, the 5700 XTAE uses a 7nm process and is accompanied by a new RDNA architecture. The architecture comes with a new set of instructions that is better suited for rendering graphic effects more efficiently and a multi-level cache hierarchy to reduce latency and improve response speed for games. The
5700 XTAE has a unique design with an embellished gold shield and Dr. Lisa Su's signature. It's Navi's current flagship card, and its main frequency is 75MHz faster than the 5700 XT. It has three display ports and one HDMI input. Like other Navi cards, the 5700 XTAE is a blower card that can suck in air through a fan and expel hot air from the back, helping to lower the computer's temperature more effectively.
5700 XT is actually 5700 XTAE, but Mhz is slower, 75 to be precise. However, some subtle differences have little effect.
At standard speed, the base clock of the 5700 XT is 1,605MHz, and the boost clock is 1,905MHz. AMD has implemented a new indicator, 1.7555MHz game clock. AMD stated that the actual actual speed of the card during gameplay will be between the base clock and the game clock. The
's design is very similar to the 5700 XTAE, but without the gorgeous gold trim or Su logo. The last card in the current
range is the RX 5700, which is also the weakest RX 5700 XT. The 5700 was released at the same time as other graphics cards and has the same new technology and architecture. The
5700 has 36 computing units, 2,304 stream processors, and an increased clock speed of 1,725, which is nearly 200MHz lower than XT. It is also equipped with 8GB GDDR6 VRAM on a 256-bit bus, which can drive 65 render output units. The
Navi 10 GPU is the first RDNA graphics processor equipped with the new AMD architecture. For AMD fans across the hardware board, this is an exciting time. We've discussed some of the specs above, but for those who want all the details, the chart below will show exactly what they offer.
As you can see, there is not much difference between the three cards, except for the price. The biggest difference is the clock speed, the most notable is the drop from 5700 XTAE to RX 5700 (1680Mhz-1465Mhz). All
cards are built with Navi 10 architecture, all use the same 7nm process, and each have 10.3 billion transistors. They all have 8GB of GDDR6 VRAM and a 256-bit bus width.
So what does all this mean for the performance of these new cards? How will they actually cope with real-world situations?
Let's take a closer look at the new Navi architecture we've heard of. If you are like me and like to keep up with the latest technology, then you will be aware of AMD's efforts to keep up with Nvidia products. This has been the case for over half a year, AMD always had to use 50-60% more power than Nvidia to achieve similar performance stats. However, with massive redesign from AMD, this may change. AMD has been quoted many times that the new architecture is truly unique, rather than an improvement over the pre-existing GCN unit. Whether this is true is a difficult question to answer.
RDNA has a new dual compute unit design with some shares, including the L1 cache. Previously, GPUs from the AMD and Intel fields were equipped with L0 cache, L2 cache, and VRAM which acts as a large L3 cache. For example, the CPU does not have L0 cache, but it has L 1 / L2 / L3 cache. AMD said that the L1 cache helps to significantly reduce latency and performance, thereby increasing efficiency.
We will also see improvements in wavefront and incremental color compression (DCC), which will further reduce latency, increase efficiency, and improve overall performance.
AMD has also implemented its new "Game Clock" on the new series of Navi cards. This is a conservative estimate
On the pulse clock.
It is interesting to hear about the great new technology implemented in these new cards, but in the end people want to know how this works in the real world.
I think it is safe to say that the 5700 XT has been released, directly competing with the GeForce RTX 2070. The initial benchmark data shows that the 5700 XT also has its number. Similarly, the RX 5700 directly competes with 2060 and once again greatly outperforms its competitors. The single threaded performance of the Navi
card is without a doubt the biggest performance improvement. It usually doesn't talk about that when it comes to GPUs, this is more of the CPU domain. However, with that said, the speed at which the GPU can process your workload is critical to the overall multi-threaded nature of the GPU.
AMD states that compared to the previous generation GCN, the instruction per clock of the new RDNA architecture has increased by 25%. They even say that the overall performance of the new card will increase by 50% while still using the same overall power and settings. The number displayed by
was generated from a PC running Part 2 with a resolution of 1440p, so there are no numbers this time.
power consumption has also improved, and the current figures show that compared with Vega 64, the performance per watt has increased by 1.5 times, even when using the most demanding GDDR6 VRAM.
For game enthusiasts, AMD is very friendly to benchmark comparison with 5700 XT's competitor 2070. The number of results is quite impressive.
5700 XT lost to 2070 in only two games (Tomb Raider and Civilization 6). Elsewhere, the 5700 XT has won, and even in Battlefield 5, its performance has increased by 22%.
However, it is not just the 5700 that will add luster to the Navi badge. Recently, it was reported that we may see more than 20 Navi brand cards in the future. Sapphire, AMD’s largest plug-in board partner, has registered another 20 trademarks with ECC. The following list shows all recently registered trademarks:
Now, before we are all headed, it is worth mentioning that not all of these trademarks will be used on actual GPUs. This is just one way AIB can cover its tracks by registering all possible combinations on the 5000 series.
This is all we know about the Navi GPU series. We are currently compiling our own benchmark data to understand how it handles the year 2070 in the real world.
Having said that, what do the current numbers mean for people who want to build PCs in today's market?
Well, first of all, it will make your life more interesting or more stressful, depending on how you look at it. Before I had Nvidia, it was the GPU of choice. However, now AMD has given us a real decision and messed up things.
5700 XT is an excellent graphics card, it seems to beat its competitors and the price is very reasonable. It will be very interesting to see how Intel performs in the next 12 months, especially when AMD seems to be out of trouble.
