No. DirectX 10, and higher, do not duplicate data in video RAM to system RAM.So hypothetically, a next-gen game (XB1 and PS4) would use 5 GB of unified RAM on their consoles, while on the PC, it would be seen as 5GB RAM + 3GB VRAM utilization?
No, you're missing the point and its one anybody who has a clue could figure out.
That makes zero sense if you actually took the time to think about what you're saying. Ok so I need the graphics power of a 7870... I go buy one... Oh wait, not good enough because it's only 2GB of ram. These explanations I expect to hear from a kid who has no clue what he/she is talking about. I must stress again that the GPU and VRAM are contained on a single device. You explanation would make sense if they weren't, but they are so it doesn't. I can't buy a 7870 then go by 3GB of VRAM, so if it actually needs 3GB of vram like it suggests, recommending a 7870 would be completely useless.
Unless you can tell me how I can meet the recommended system requirements by running this game on a 7870, those recommendations are erroneous and your explanation baseless. So please enlighten me on how I can accomplish this.
They could also make a dual core running at 6GHz if they really wanted to, that doesn't meant it's going to be in the recommended system req's... When was the last time you saw system requirements posted recommending hardware that didn't exist? I just don't understand why it's so hard for you to acknowledge there's a glaring error there. Sorry if I'm being condescending, I just think it's funny how someone who's posturing as a techie is trying so hard to defend requirements based on hardware that doesn't even exist and pretending it's totally legitimate to recommend GPU and VRAM configurations that you can't actually get.
It is an assumption, you're assuming the existence of a console version = the PC version being held back. It is just as likely the PC version was made as well as it possibly could be, and the console version is simply paired-down hugely.
No, there's an enormous seam between the two: one is accessible via pointers into addresses and the other is accessible only through graphics APIs (which merely give you abstracted handles to those resources). You can only get a resource into video memory by going through the API abstractions.Both system RAM and video RAM are mapped in one contiguous block of addresses, which allows (nearly) seamless sharing of resources between the two (from a software perspective).
Look, Shirlock, a Newegg search turns up five 660s and one 7850 with 3GB+ of VRAM.

What's your brilliant theory, that the developers don't know most 660s come with only 2GB VRAM? You must think you're a genius if you think everyone else is stupid.
I don't need a theory, I just know how to read. Specs say 7870. I don't think everyone else is stupid. You're the only one who's continuing to argue about it.
Offer for tutoring is still on the table.
Shirlock,
Only 2 months away. I'll wait till its out....and then throw a mini kerfuffle.....then probably upgrade. It's how it usually goes =)
Same size "maps"? Most games these days use resource-streaming. There aren't really individual maps, just an overall draw distance with an LOD system. This can be dynamically adjusted based on the performance of the hardware with ease.Both PC and console versions tend to have the same size maps, same number of NPCs, same AI etc. So while those may not directly affect VRAM usage, they certain indirectly affect it.
Pretty darn easy to turn a few nobs and instantly have 4x the number of NPCs, 4x the amount of AI, and 4x the draw distance (before LOD kicks in) and totally blow away what any current console can reasonably handle.It's possible game engines like DICE's make it easy to port between PC and console, but I think it's more likely that having to fit the game into the consoles' 512M of shared ram limits what developers can do.
Do a lot of video encoding? Perfect excuse, right there. You'll easily see a 20% performance boost over a 2500kI really need an excuse to get a 2600k....
Wonder how much those 8 our 12 GB cards will cost...
Let's talk when we can build a system that meets the recommended spec using the recommended 7870.
Same number of NPCs? I'm sorry? Go ahead and load up an NPC-heavy game like Assassin's Creed some time. PC version blows the consoles away...

And lets not forget physics. Batman Arkham City has some serious stuff going on when hardware accelerated PhysX is available. This includes a full fluid simulation on fog so that you can leave wakes and ripples in it. Amazing stuff, and again, something not even next-gen consoles will be doing.
You do realize they're recommending a class of card, not specific cards. And you do realize you must meet all the requirements on the list, not just some of them. So you need a 7870 class card, 8GB RAM, Windows 8, etc and 3GB VRAM.
Such a card already exists, it's a 3GB 660.
More such cards will likely be released soon, 660/7870 class with 3GB RAM.
If this doesn't make sense to you, you're beyond help.
7870 is a specific model, not a class. The "class" would be 7900 series. If this doesn't make sense to you, you're beyond help. Not that it matters, you can call 7870 a class, a series, a sepecific model, it's still 2GB.
You can continue to make excuses or simply admit there's an error there.
bf3 was so bug filled, i'll pass on bf4.

I think you gentlemen need to sit back and reflect on what it is you're arguing about and how ridiculous it must seem to those on the sidelines.There were numerous HD7870 'models', just like there are numerous Chevy 1500's. Seriously dude, you sound like a democrat losing an argument.

Why don't you contact DICE and tell them how you, in your infinite wisdom, caught them in an error.
Damn Democrats....
Not necessary, I know what will and won't work. I wasn't the first to catch it anyway. When it was caught however, I recognized it as an error and didn't vehemently defend it by pointing to cards that aren't 7870's as my "proof."
Rare cases?rare cases, most games have the same draw distance, especially indoors, same number of NPCs, most games aren't PhysX enabled etc. So there's plenty of room for improvement with the new consoles' power.
Did any of us say that a 3GB HD7870 exists? I definitely didn't. Are you really going to keep this up?
Rare cases?
Most PC games I've played have much better draw distance than their console counterparts. In modern games, this usually shows up as high-quality models being displayed farther into the distance before being swapped for lower-quality ones. Did you think I was referring to some archaic "distance fog" setup?
So, while the console version can technically see as far as the PC version, the the detail ramp is much more severe so that anemic console hardware isn't overwhelmed by it. The quality ends up being much lower on the console side of things in order to maintain such high overall draw distance.
And I already pointed out that Assassin's Creed can have a much larger number of NPC's in its PC version (same goes for its sequels). Newer games like Hitman Absolution manage to get an impressive number of NPC's onto the screen (even on consoles) but if you look carefully you'll notice the distant ones are significantly dumbed down on the console versions. There are many more repeated models, repeated animations, and a general lack of AI complexity on the NPC's far away from the player.
None of this is a problem for the PC version. No trouble handling these levels with their complexity maxed out.
And there are actually a LOT of games that use PhysX for physics, it's just very few of them that make use of hardware-acceleration (even if it's available). This is probably one of the few areas where consoles are actually holding up PC development; they have no way of running these complex physics simulations, so gameplay has to be altered to exclude any scenarios that requires intensive physics. And no, the new consoles do not rectify this situation, they still don't have enough power (fitting all assets into available RAM is not the problem, raw computing power is).
So, circling back around... just because consoles have a limited quantity of RAM does not always, if ever, mean these games are designed specifically to work within that quantity of RAM. It's equally likely that they were scaled down to the respective systems after the fact.
You do know the difference between an inclusive list and an exclusive list, right?Look in the mirror buddy, you're just as guilty of "keeping this up" as I am and I'm not the one arguing with something I agree with.

Just man up and admit you're crying cause you just bought two 2GB 680s before this announcement.
Bought them well before the announcement. Confidant at my resolution (1200p) I can crank up the settings and be CPU limited before i'm GPU limited, same as I am with BF3.
