AMD Polaris RX 480 Specs - 8GB VRAM, 256bit Bus & 2304 GCN 4.0 Cores

An entry of AMD's Polaris 10 GPU, the flagship of the Polaris family unit, has only been spotted on the SiSoft Sandra benchmarking database. Polaris 10 is one of two Polaris GPUs, the other being Polaris 11. The entry in question has a valid result and includes the specifications for the Polaris x GPU. Namely the GCN core count, memory interface, capacity and clock speed.

Despite eleven existence a larger number than ten, Polaris 10 is actually the larger GPU of the 2. Principal Architect & caput of AMD's Radeon Technologies Group confirmed that the naming scheme is time-based & Polaris 10 had simply been designed before Polaris 11, hence the smaller numerical designation.

Polaris 10 is AMD's mid-range 14nm FinFET graphics fleck, Polaris xi is the smallest of the family and Vega 10 is the HBM2 powered high-terminate flagship 14nm GPU launching in 2022 to succeed the Fury lineup. It will feature AMD'south next generation Vega architecture and will be the company's first GPU to characteristic second generation High Bandwidth Memory.

AMD Polaris 10 Powered RX 480 Specs Leaked - Features 2304 GCN iv.0 Cores, 8GB VRAM & 256bit Bus

The SiSoft entry points to an 8GB GDDR5/10, 256bit GPU with 2304 4th generation GCN cores. Interestingly this is the verbal same memory chapters & double-decker configuration we've seen on Nvidia's upcoming GP104 Pascal based GTX 1080 & GTX 1070 graphics cards.

2304 GCN cores is really less than the R9 390, but the GCN 4.0 compages is significantly more than powerful overall according to AMD'due south caput of the Radeon Technologies Grouping and Principal Architect Raja Koduri.  So just like the transition from Kepler to Maxwell we're going to come across core counts go down and performance go upwardly.

This particular Polaris ten chip carries the 0x67DF device ID, which according to AMD's recently released driver source code indicates that we're likely at the cutting downwardly variant of Polaris 10. Which means that we're looking at the Polaris ten GPU configuration that we're going to end upward seeing every bit the RX 480 rather than the RX 480X. The latter volition end upward with more than GCN cores and higher performance.

The full Polaris ten GPU with the deviceID 0x67C0 will possible feature 2816 GCN cores like Hawaii XT. The driver source lawmaking likewise confirmed that Polaris 10 is indeed Ellesemere and Polaris 11 is Baffin. Both of which are Chill Islands GPU code names that we had covered extensively for so long.

There'due south no entry for the total Polaris ten chip in the database but however then we don't know how many GCN cores it will feature, 2816 beingness a safety guess. Seeing as how the R9 390 & 390X perform remarkably close to each other AMD will have likely decided to distance the RX 480X further from the RX 480. Like to how the R9 Fury has 512 fewer GCN cores compared to the Fury X, unlike the R9 390 which only has 256 fewer GCNs compared to its large brother the R9 390X.

The SiSoft entry also includes the clock speed of the card, which at 800Mhz is surprisingly low. And so we're likely looking at an early engineering sample hither. Especially considering the fact that 14nm FinFET clocks much higher than 28nm. And then I'd expect frequencies upwardly of ~1150Mhz on the production chips.
With that in heed, the GPU actually did well in the criterion and came ahead of the GTX Titan Blackness. Which features a full GK110 chip and coincidentally is faster than a 2816 GCN core Hawaii XT GPU. Also funnily plenty this is very shut to the performance we've seen from the leaked GTX 1080 and GTX 1070 benchmarks.

Despite the low clock speed & the lower number of GCN cores this particular configuration of Polaris 10 nonetheless performed alee of where you'd wait an R9 290X to perform. This in plow indicates that 4th generation GCN cores perform measurably better per clock than their predecessors.

Raja Koduri, Senior Vice President and Primary Architect, Radeon Technologies Group, speaking with Venturebeat.com :
We've redesigned many blocks in our cores. Nosotros've redesigned the main processor, a new geometry processor, a completely new quaternary-generation Graphics Cadre Next with a very high increment in performance .

Also worthy of note is that this Polaris 10 engineering sample features 6Gbps GDDR5 retentivity chips rather than GDDR5X which combined with a 256bit charabanc delivers 192GB/s of bandwidth. Exactly half the memory bandwidth of the R9 390 and 390X, which indicates that production Polaris 10 cards could feature 12Gbps GDDR5X retentiveness instead to deliver the same amount of bandwidth.

Polaris eleven And Polaris 10 Are AMD's Fastest And Nearly Power Efficient GPUs To Appointment

Speaking with Venturebeat.com Raja asserted that both Polaris 11 and Polaris 10 are "extremely ability efficient".  He connected to say that these GPUs and the Polaris architecture in full general will deliver "our most revolutionary bound in performance then far". Which are mighty heady words for Radeon enthusiasts coming from the head of AMD's Radeon Technologies Group.

Raja too spoke briefly about the makeup of the new graphics architecture. Featuring a new geometry processor, a redesigned control processor and completely new 4th generation Graphics Cadre Next compute units – the main component of all mod AMD GPUs – with "a very high increase in performance". He also spoke about the new multimedia cores and the new display engine in Polaris. Which will enable gamers to record and stream 4K gameplay at 60 FPS with no operation price.

Polaris x & Polaris 11 Will Feature GDDR5/10

Information technology's true that we will accept to wait until next year for HBM2 GPUs from either Nvidia or AMD. Nvidia's GP104 powered GTX 1080 and GTX 1070 cards - not official names - are reportedly configured for GDDR5X. And there's about no chance of neither Nvidia or AMD risking production of big GPUs like GP100 or Vega 10 this early in the nodes' lifecycles. Neither 16nm or 14nm volition exist mature enough for big GPU launches this twelvemonth. This is all assuming HBM2 production has already sufficiently ramped up, which hasn't yet.

Despite that, what we're getting this twelvemonth is still going to deliver a very pregnant jump in performance, performance per watt and performance per dollar. This is cheers to the much needed arrival of FinFET manufacturing technology as well equally GDDR5X.

This update to the GDDR5 retentiveness spec is simple enough. Double the chapters and double the data rate of GDDR5 with minimal alterations to the protocol. That in turn means existing GDDR5 memory controllers volition only need minor blueprint updates to be compatible with GDDR5X. Which saves Nvidia and AMD a lot of engineering effort and price. Double the bandwidth as well means GDDR5X will do more than than an adequate job of keeping faster, bigger, next generation FinFET GPUs happy and well fed until HBM2 arrives in 2022.

At double the speed of GDDR5, a GPU configured with a 256bit memory interface can have admission to up to 448GB/s of bandwidth and 8GB of memory. That's double the bandwidth available to the GTX 980 and twice the capacity. It's also 33% more bandwidth than what's available to the GTX Titan X. With that in perspective GDDR5X is conspicuously going to be more than enough for Nvidia's GP104 GPU and AMD'south Polaris x GPU.

Information technology'due south not every day that we go GPUs with 2.5x better perf/watt, in fact not ever. This is the biggest jump from ane generation to the side by side that we have ever seen. Only information technology's not all almost efficiency, Raja is also promising the "most revolutionary bound in functioning so far".

Raja Koduri revealed at Capsaicin that AMD'southward focus with Polaris is all virtually giving gamers a "sweetness" performance per dollar bargain. And this is exactly what Polaris ten and Polaris eleven will do. AMD announced that Polaris graphics cards are going to be released mid 2022, this summer. AMD's CEO Lisa Su later elaborated further, saying that Polaris graphics cards will exist available on shelves and in notebooks earlier the dorsum to schoolhouse flavour this twelvemonth.

There's likewise been a lot of buzz around Nvidia potentially demoing Pascal at GTC in April, with GTX 1080 and GTX 1070 - not official names - graphics cards launching in the summer. AMD has already demoed Polaris 11 at CES and Polaris 10 at GDC, and then nosotros can't wait to come across Pascal in activity. Hopefully side by side month.
