Good God. Sapphire Tri-X R9 390X 8G D5: GPU 2816 Stream Processors 28 nm Graphics Core Next (GCN) 1055 MHz Engine Clock ----------------------------------------------------- Interface PCI-Express 3.0 ----------------------------------------------------- Memory 512 bit Memory Bus GDDR5 Memory Type 6000 MHz Effective Memory Clock 8192 MB Size ----------------------------------------------------- System Requirement 750 Watt Power Supply (Suggestion) 2 x 8-pin AUX Power Connector Price? About €475.- Can't afford the 'X' version? There's also a normal version, also with 8GB. At about €370.- For American prices, referencing this Powercolor review that says $450 for the X. (Edit: the other price I gave originally was for a 290x, not plain 390.) |

The Sapphire R9 390X & R9 390 are selling for $429 & $329 USD respectively at the major retailers like Amazon & Newegg. A R9 Fury X, with its 8601 GFLOPS & same power requirements at the 390X, would be nice, but selling for $649 it is close to what I spend on a whole system sans the GPU. Personally I've looking at the R9 380 Nitro as a replacement for the HD 6870 in my gaming machine. I had been sticking with 150w cards, but they are not doing much development in that power range these days. SO I'm going to have to move up.

I just wonder if the full 8GB can be used. And what kind of game you need for that. Although the new upcoming Deus Ex might be hitting it hard, nothing said about the likes of Doom 4, Hitman and maybe Fallout 4. Hope they don't expect me to play those with an Oculus Rift. :) Of course, on the Fury X you pay for the high bandwidth memory, not so much for the water cooler. At 128GB/sec versus just 28GB/sec on GDDR5, that's no wonder. |

Just have a look at the power consumption-375W. If you crunch with it 24/7 at (call it 300W) that will cost you about $500 or more per year in electricity alone. |

Hope they don't expect me to play those with an Oculus Rift. :) I don't imagine either company will be having that issue again after the latest 3.5GB usable out of 4GB NV faced with one of their GPUs. Once you start driving several monitors at 4K(AKA 2160p, UHD, or 3840 x 2160) resolution using all of that memory would not be hard to use. If they implemented DisplayPort v1.3 an 8K monitor could also be used. Apparently GTA V on PC running 4K at 60 FPS is a good example of needing massively high end hardware. Actually running 4K at 30 FPS for GTA V requires some pretty hefty hardware too. I just had to replace my monitor & my new one is only 1080. So I'm not worried about 4K gaming just yet. However when I replace my 61" TV I will be getting a 4K one. So I may still need to consider gaming on that. For SETI@home use I don't think more that 2GB is needed running several instances. Maybe there could be some way for the apps to use more of the memory, if present, to speed things up in some way that no one has current thought to do.

Just have a look at the power consumption-375W. The listed power consumption for those GPUs is less. Sapphire is listing the maximum power spec for the PCIe slot and power connectors for the cards. The actual spec for a 390X is 275W. I think the general rule of thumb is that we normally see about 80% of the rated TDP running SETI@home apps. Which puts the power consumption closer to 220W. However the whole system would probably be looking at around 300w. 220w running 24/7 = 1927 KWh/yr, or 161 KWh/mo 300w running 24/7 = 2628 KWh/yr, or 219 KWh/mo SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

I don't imagine either company will be having that issue again after the latest 3.5GB usable out of 4GB NV faced with one of their GPUs. That was due to the memory configuration on the GTX 970, being split in one segment of 3.5GB and one of 512MB. The latter is only being addressed when a game or program actually tells it needs it. |

I don't imagine either company will be having that issue again after the latest 3.5GB usable out of 4GB NV faced with one of their GPUs. Ah right, it was a speed issue not actually accessing it. I only keep tabs on so much info about NV hardware. Running 1080 it may not be an issue today, but cool kids are running 4K these days. Which does often uses >3.5GB of memory. I generally plan to use my GPUs for more than a year or however long the GPU releases cycles is. So something today may not be able to make full use of 8GB on the R9 390X, but it might soon enough. Currently the R3 390's only come in 8GB configurations. So even if you can ever use all of it there isn't another option. The main question I come up with after looking at NVIDIA's response to the issue. Why does the 980 slow down so much in the same situations when it doesn't have restrictions accessing all of its memory? Either memory bandwidth isn't as important as they have been trying to tell us, or those titles are just not that memory intensive.

Sapphire Tri-X R9 390X 8G D5: are £350 in the UK :-( Plus of course £80-100 for a decent PSU to go with it. That's about $550 USD. With them selling for $429 here I imagine shipping to the UK would cost less than $130... OK I just checked and it isn't that much less. $90 for 3-5 day shipping. There goes all my plans to makes lots of money selling GPUs to UK crunchers! SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

Plus of course the fact that one may get hit for import tax, which has to be paid before most carriers will release the goods :-( Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |
