Rumour and speculation: AMD 300 series specs

AMD’s 300 series cards are coming soon-ish, ready to deliver a knockout punch to Nvidia and its reigning Maxwell-based cards, the fabled 900 series. The problem though is that beyond speculation, rumour, conjecture and idle guessing, we have very little idea of what to expect from AMD’s new cards, or when exactly they might be out. Here’s some more speculation.

According to German-language PC enthusiast site 3Dcenter (via Videocardz), they’ve got the lowdown on what we can expect from AMD’s 300 series – including speculation on a mammothine, beastly, Eskom-destroying twin GPU card, the R9 395X.

GPU Possible Specs Launch Date
AMD Radeon R9 395X2 Bermuda (Fiji x2) GCN 1.3; 8192 (?) Cores; 8192-bit 8GB HBM Q4 2015
AMD Radeon R9 390X Fiji XT GCN 1.3; 4096 (?) Cores; 4096-bit 4GB HBM Q2 2015
AMD Radeon R9 390 Fiji PRO GCN 1.3; 3840 (?) Cores; 4096-bit 4GB HBM Q2 2015
AMD Radeon R9 385X Fiji CE (?) GCN 1.3; 3328 (?) Cores; 2048-bit 2GB HBM (?)
AMD Radeon R9 380X Grenada XTX (Hawaii) GCN 1.1; 2816 Cores; 512-bit 4GB GDDR5 Q2 2015
AMD Radeon R9 380 Grenada PRO (Hawaii) GCN 1.1; 2560 Cores; 512-bit 4GB GDDR5 Q2 2015
AMD Radeon R9 370X Tonga XT GCN 1.2; 2048 Cores; 384-bit 3GB GDDR5 Q2 2015
AMD Radeon R9 370 Tonga PRO GCN 1.2; 1792 Cores; 256-bit 2GB GDDR5 Q2 2015
AMD Radeon R9 360X Trinidad GCN 1.3; (?) Cores; 256-bit 2GB GDDR5 Q1 2015
AMD Radeon R9 360 Trinidad GCN 1.3; (?) Cores; 256-bit 2GB GDDR5 Q1 2015

The 395X, if it’s real, would be a successor to the Vesuvius, the dual-GPU behemoth R9 295X2 – essentially two of its possible new flagships duct-taped together. The Fiji-based R390X and 390 would come next, powered by 4096 and 3840 cores and 4GB of stacked HBM memory, sporting version 1.3 of AMD’s Graphics Core Next technology. Following that we’d have the rebranded Hawaii-based cards, now called Grenada, serving as the base high-level cards – each sporting regular old GDDR 5.

Take this all with a rather large grain of salt, of course – while 3D centre says its information is mostly directly from graphics card manufacturers, they do admit that much of it is down to a fair bit of speculation. I really wish AMD would give u some concrete fact about their upcoming cards – especially where a release date is concerned. Pc gamers need to know if they should stick it out, or go with Nvidia’s 970…even if it does only have 3.5GB of fast VRAM.

Editor. I'm old, grumpy and more than just a little cynical. One day, I found myself in possession of a NES, and a copy of Super Mario Bros 3. It was that game that made me realise that games were more than just toys to idly while away time - they were capable of being masterpieces. I'm here now, looking for more of those masterpieces.
