AMD “Su Ma” zooms in one after another! On the evening of October 27th, AMD officially announced the acquisition of Xilinx for a total of 35 billion U.S. dollars, which became another large-scale transaction in the semiconductor industry after NVIDIA announced the acquisition of Arm and the Korean company SK Hynix plans to acquire Intel’s NAND business. Today, AMD has released the RX 6000 series of graphics cards with a new RDNA 2 micro-architecture, which has achieved all-round improvements in performance, energy efficiency, and game performance.

This morning, AMD officially released the Radeon RX 6000 series of graphics cards: Radeon RX 6800, 6800XT and 6900XT, against the latest GeForce RTX 30 series graphics cards of Nvidia.
These three products are based on AMD’s latest RDNA 2 architecture. AMD stated that the RDNA architecture is “born with game DNA” and that the technology is officially certified as “will be used in PS5 and XboxSeries X game consoles.” The performance per watt of the first-generation RDNA architecture is 50% higher than that of the GCN architecture. Today, the RDNA 2 architecture is 50% higher per watt.
The new RDNA2 architecture brings a number of innovations, including high-performance CU computing unit, revolutionary infinite cache technology, breakthrough high core frequency design, etc.
These latest Radeon graphics cards will support hardware accelerated ray tracing for next-generation games. AMD is expected to compete with NVIDIA in 4K and 1440p PC gaming.
After the press conference, AMD officially announced the time to market and prices of several graphics cards. Among them, Radeon RX 6800 and Radeon RX 6800XT graphics cards are expected to be listed on November 18, 2020, priced at 4599 yuan and 5,099 yuan, respectively. Radeon RX 6900XT is expected to be available on December 8, 2020, priced at 7,999 yuan.
At present, the official website of Nvidia shows that the price of GEFORCE RTX 3070 starts at 3899 yuan, the price of RTX 3080 starts at 5499 yuan, and the price of RTX 3090 starts at 11999 yuan.
Yesterday, AMD just announced 2020Financial report for the third quarter of the year. The data shows that the company’s third-quarter turnover was US$2.8 billion, an increase of 56% year-on-year and a 45% month-on-month increase. Net income and earnings per share more than doubled year-on-year.
Radeon RX 6800
The Radeon RX 6800, priced at $579, is benchmarked against the Nvidia RTX 2080 Ti. AMD said it “has surpassed the performance of the Nvidia RTX 2080 Ti in some 4K and 1440p game tests“, the test The result is shown in the figure below. It is equipped with 60 computing units, a base frequency of 1815Mhz and a boost frequency of 2105Mhz, 16.17 teraflops of single-precision floating-point performance and 16GB of GDDR6 memory.

The power consumption of Radeon RX 6800 is 250W, which is 10W lower than the official version of NVIDIA RTX 2080 Ti.
AMD has not benchmarked it with RTX 3070, but from the price of RTX 3070 at 399 USD and RTX 3070 Ti at 499 USD, if the performance of the three are equal, then the competitive advantage of Radeon RX 6800 can be It’s not so obvious.
Radeon RX 6800 XT
The Radeon RX 6800 XT, priced at $649, is a benchmark against Nvidia’s RTX 3080, and is expected to meet or exceed the performance of Nvidia’s new graphics cards in 4k and 1440p games, and the price is $50 lower. It is equipped with 16GB of GDDR6 memory, a base frequency of 2015Mhz, a boost frequency of 2250Mhz, a single-precision floating point performance of 20.74 teraflops and 72 computing units.
In the early benchmark test results, the Radeon RX 6800 XT was used in 4k games such as “Battlefield 5”, “Borders 3”, “Call of Duty: Modern Warfare”, “Forza Horizon 4” The data performance of RTX 3080 is better than that of Nvidia RTX 3080; it is comparable to RTX 3080 in the games of Tomb Raider, Gears of War 5 and Doom Eternal. This means that Radeon RX 6800 XT is expected to bring more stable 4k gaming performance.

In the 1440p benchmark test of the same game, AMD’s Radeon RX 6800 XT performs as good as Nvidia’s RTX 3080, but has lower power consumption: RTX 3080 consumes up to 320W and RX6800 XT consumes 300W .

Radeon RX 6900 XT
The highest-priced Radeon RX 6900 XT is the flagship model of the RX6000 series, which is a benchmark against Nvidia’s RTX 3090. It has 80 computing units, 28 MB of new AMD Infinity Cache and 16GB of dedicated GDDR6 video memory. In terms of frequency, the base frequency of RX 6900 XT is 2015MHz, and the boost frequency is 2250MHz. AMD claims that the total power consumption of this graphics card is only 300W, which is better than RTX3090 Low 50W.
AMD said that the RX 6900 XT is built for demanding next-generation games and performs well at 4K resolution. With the 6900XT graphics card, the performance per watt of the RDNA 2 architecture is up to 65% higher than the previous generation.
From AMD’s own evaluation results, the RX 6900 XT defeated the RTX 3090 in a variety of games, including “Battlefield 5”, “Forza Motorsport Horizon 4”, “Gears of War 5” and so on.
The three new graphics cards all use the traditional 2.5-slot design, conventional PCIe interface and a three-fan system. Unlike Nvidia, AMD has not reduced the PCB size, nor has it introduced a new 12-pin power connector.
It can be noted that all three graphics cards use 16GB of GDDR6 video memory, which is better than RTX 3070(8GB) and RTX 3080(10GB) provides more video memory, but less than the 24GB on the RTX 3090. Nvidia’s RTX 3080 and 3090 both use faster GDDR6X, but AMD has abandoned this more expensive and more power-consuming high-speed module.
New AMD RDNA 2 architecture GPU unveiled
RDNA is the code name of the GPU micro-architecture and supporting instruction set developed by AMD. The first GPU product series to adopt RDNA is the Radeon RX 5000 series GPU launched by AMD on July 7, 2019. The RDNA 2 launched this time is the follow-up product of the first-generation RDNA micro-architecture and is used in the latest Radeon RX 6000 series graphics cards.
AMD revealed that the performance per watt of RDNA 2 is 50% higher than that of the first-generation RDNA microarchitecture, and this goal is achieved entirely through architectural improvements rather than process improvements. In general,RDNA 2 has achieved significant improvements in performance, energy efficiency, and gaming experience.
First of all, in terms of performance, compared with the AMD Radeon RX 5700 XT graphics card based on the first-generation RDNA architecture, the AMD RDNA2 game architecture is better than those in Battlefield V, Doom: Eternal, and Resident Evil 3 Some specific games can provide up to 2 times the performance.
Secondly, in order to achieve comparisonThe first-generation RDNA has achieved a performance increase of 54% per watt. AMD has made all-round improvements in three aspects: acceleration frequency, energy efficiency, and Infinity Cache architecture.
Compared with the first-generation RDNA architecture design, the RDNA 2 architecture can increase the acceleration frequency by up to 30% at the same energy consumption level through high-speed design methods.
AMD uses advanced energy-saving technologies to achieve up to 30% energy efficiency improvement for each computing unit in each cycle. This is mainly achieved through three aspects: fine-grained gated clocks throughout, more effective pipeline rebalancing, and data paths redesigned for efficient movement.
AMD has launched a new Infinity Cache technology that can provide greater bandwidth and lower power consumption. AMD revealed that Infinity Cache is based on Zen3 L3 cache adjustmentThen, the three graphics cards are configured with 128MB, and the benefits include access to ray tracing data, reducing frequent calls to video memory, and achieving greater throughput bandwidth than 384bit under 256bit width.
Finally, AMD revealed that RDNA 2 will be the DX12 Ultimate-level architecture, focusing on the following 4 functions: ray tracing, Tier 2 level variable rate shading, grid rendering and sampler feedback.
Some time ago, the news that the Nvidia RTX 3080 was stolen by the scalpers caused a lot of complaints, and the 3090, which was priced at 11,999 yuan, had to be bought at an increase. Today, AMD’s new product launch seems to provide you with another choice.
