AMD Radeon RX 400 Series Naming Scheme Reveals 9 Tiers
AMD has finally detailed its new Radeon RX 400 series naming scheme.
The Radeon RX 400 series is split into two subseries: the RX 400 and 400. The Radeon RX parts offer compute performance of 1.5 TFLOPS or more, and memory bandwidth of at least 100 GB/s. The cards that don’t offer that type of performance won’t use the RX prefix.
According to AMD, they will be using XX5 revisions as well, which means faster variants of the cards might arrive over time once yields are improved and leakage is minimized. Or, AMD could simply release higher-clocked versions to take on Nvidia counterparts.
The company differentiates Radeon RX 400 series into 9 tiers which are gathered into 5 groups. Tier 6 (46X cards) might use both the RX and non-RX prefix, which means the recently announced Radeon RX 460 might have a younger sibling, the non-RX 460.
Tier 9 will obviously include top of the line video cards, namely Radeon RX 490 and RX 495. AMD says both cards are designed for 4K resolution with memory bus higher than 256-bits.
The Radeon RX 490 has already been spotted listed in an AMD document detailing game bundling with their products. The high performance card is expected to hit the market before the end of the year on December 31st.
AMD Radeon RX 490 is exepected to be based on the next generation Vega 10 GPU, which was recently teased by AMD’s Radeon boss Raja Koduri. Built using the latest 14nm FinFET process node and GCN 4.0, this high performance card could feature HBM2 memory, and compete against the GeForce GTX 1080 and the rumored GTX 1080 Ti.
The Radeon RX 480, the only launched card in the series, falls under the Tier 8 and is being positioned as the 1440p graphics solution. Priced at just $199, the RX 480 is a perfect option for PC builders on a budget. It offers performance comparable to Nvidia GeForce GTX 970 or Radeon R9 390, but is far more efficient.
