The two people we speak to are Nick Stam (pictured), the technical marketing director for GeForce and Bryan Del Rizzo, PR manager in the US. We start by asking them what they feel about losing the performance leadership.
"Is that interesting?" says Del Rizzo. "To some people maybe, but it took two of their GPUs to beat one of ours. We have had dual GPU cards and it's feasible that it may happen again."

That last point was intriguing. In our review of the 4870 X2, HEXUS.net editor Tarinder Sandhu said: "We'll have to wait for the GTX 200-series to go on a process diet, to 55nm, and then, just perhaps, we'll see a GX2 based on GeForce GTX 260."
While we're unable to draw either of them on whether or not this will happen, when we ask them if they expect to regain the performance leadership this year, Stam says "Yes".
That's as much as you're going to get on that topic for now and we move swiftly back to the 4870 X2. "Is that product the best product you can buy for a PC?" asks Del Rizzo. "A lot of people care about power consumption. Two GTX 260s have lower power consumption than one 4870 X2. In the Asia-Pacific region, for example, they're sensitive about power consumption."
Stam is keen to point out that he thinks NVIDIA's multi GPU platform has advantages over AMD's. "We've done our own testing of SLI vs Crossfire and we see a lot of issues with Crossfire. SLI is far more developed and doesn't have as many issues."

Having the overall performance leadership isn't just about selling a few top-end cards, it's also about the ‘halo effect' - the trickle down of brand kudos that comes with having a widely acclaimed product. This phenomenon has been associated with the resurgence of the Apple Mac brand on the back of the success of the iPod so it's not insignificant.
"It gets people interested in your brand as long as you can support it in all segments," says Del Rizzo. "The 4850 is not selling well in US etail. The 4870 is selling a bit better. Are people going to look at 4870 X2 reviews and say ‘I'm going to buy an ATI card'? A single great product from AMD isn't going to erase years of brand inequality. If AMD is able to deliver for years then maybe, but let's see."
"AMD is primarily a CPU company and they have problems to overcome there, that may inhibit continued success in GPUs. At the end of the day it's about more than just coming to the market with one interesting product."
But NVIDIA's counter-offensive isn't just about slagging off AMD. It has also been trying to make a big noise about all the other things a GPU can do other than just process graphics. Principal among these are PhysX - which allows separate processing of physical events like collisions and explosions within games - and CUDA - which is a programming language for creating applications to run on the GPU rather than the CPU.
That's all great, but the problem PhysX had in the years before NVIDIA bought the company behind it - Ageia - earlier this year, was that there were no games written to utilise PhysX. So it was pretty useless to most. The same accusation has also been levelled at CUDA: where are the applications? "There are 40 games coming out with PhysXin the next seven months; over 20 this year, and you're going to see at least three or four more consumer apps coming out for CUDA this fall," says Del Rizzo.

The other fly in the ointment for NVIDIA is that Intel already owns the other main physics technology - Havok - and AMD has decided to cozy up to them on the matter of physics. "I'm getting frustrated with people comparing Havok and PhysX and saying they're the same thing," says Del Rizzo. "Havok can only run on the CPU, whereas PhysX can run on the GPU and CPU."
Can anyone use CUDA? "If AMD wanted to they could produce CUDA stuff; it's not a proprietary or closed interface," says Del Rizzo. "AMD has never come to us and said ‘We need help doing CUDA.' And they don't even need to because it's open - no strings attached. If AMD wants to use CUDA they can and it's the same with PhysX. If they're using CUDA there's nothing to pay us for. If I was Intel, I'd make Havok work on Larrabee."
Ah, Larrabee. Surely that's got NVIDIA quaking in its collective boots. "Larrabee is interesting because it doesn't exist," says Stam. "All it really does is legitimise the importance of the GPU. You should ask Intel: ‘Won't Larrabee jeopardise their CPU operations?' Also, look at Intel's history with software. There is so much software IP with NVIDIA and ATI; does Intel have the software expertise?"
Not necessarily, but it can buy it. Surely it's just a matter of time before Intel catches up. We leave the final word to Stam: "The overall pie is going to get bigger. Our belief is that we're going to grow along with the expanding market and so will AMD if they're still around."
He just couldn't resist.



最近Hexus对NVIDIA两位高层：技术营销总监Nick Stam和美国公关经理Bryan Del Rizzo进行了采访。采访主要谈到了NVIDIA最近在性能上败给HD 4870 X2的敏感话题。然而Nick Stam在采访中却透露了爆炸性的消息，也就是玩家普遍关心，双GTX200核心的显卡的问题。
　　技术营销总监Nick Stam在采访中谈到：“你们觉得HD 4870 X2很新奇吗？不！它只是两个GPU而已，两个GPU打败一个GPU没什么奇怪的，我们也曾经出过9800 GX2，也可能在GTX 200上再次出现。”“我们将在年内夺回性能上的优势。”，另外，“两张GTX 260的功耗比一张HD 4870 X2还低，这也是我们的优势之一。”Nick Stam如是说。 　　后面还谈到为何HD 4870 X2会如此受瞩目的问题，美国公关经理Del Rizzo则认为这只是人们受到了光环效应的影响。“前阵子HD 4870不错，那么人们就理所当然地认为HD 4870 x2也是好样的。但是这种光环效应很快就会消失，除非AMD能继续保持一段时间的性价比优势。”Del Rizzo相信NVIDIA拥有CUDA、PHysX等不可比拟的技术，他们很愿意与AMD比下去。




　　Del Rizzo在采访中还谈到了Havok、CUDA和Larrabee。
　　Del Rizzo介绍了CUDA的开放性和免费性。而当记者拿Havok与PhysX相比的时候，Del Rizzo不以为然：“Havok与PhysX是两个根本无法相比的技术，Havok只能用CPU运行，而PhysX既可以用CPU运行，也可以用GPU运行。”
　　那么Larrabee呢？“Larrabee实在是太有趣了”Nick Stam说，“他有趣到根本就不存在。Larrabee的出现除了告诉人们GPU的重要性外一无是处，而它的架构只会让CPU指令和GPU指令相互混淆。你们看看Intel的软件历史就知道他们在软件方面有多糟糕。”

人家nv本身都表示要夺回性能领导地位了，为何某些人非要坚持自己还是最牛x的？何必呢

如果这张图是用GPU渲染出来的，那NV就没有说谎 :p

GT260 GX2，耗电有望比 4870X2 更低，所以的确有可能。

有些看不懂英文？
To some people maybe, but it took two of their GPUs to beat one of ours.
某些不管GPU数量，并且无视顶级CF/SLI的人来说，R700 vs GTX280这一点确实成立的
但是这只对部分人有意义，别人可不会这么认为。{titter:]

虽然在单GPU显卡以及顶级多卡配置方面，NV拥有优势，但是单PCI-E槽这个狭窄领域NV也有意向要完胜A卡{biggrin:] {victory:]

面对气势汹汹的Larrabee，
NV所做的是，闭上眼睛，说：
It just dose not exist!

我不得不说，这个心态是很好的

貌似这是扣肉刚出的时候AMD说的话{lol:]

单卡性能落后就是落后了
因为cf和sli有主板限制

单pcie槽还是最好的

不过这样，x2 x3 x4出来都可以yy了

原来单pci-e是狭窄的，cf和SLI才是主流...
我又学到东西了，o-yeah{victory:]{lol:]

不仅仅是单PCI-E好吗？还得去掉单PCI-E单GPU，拜托
难道单PCI-E多GPU不狭隘？你周围用R700的人很多？{titter:]

logitechMX518

你身边用还不算顶级的GTX280的人很多？哦～我忘了，j神自己还美用上GTX280呢

吵这么乐呵有意思啊？

时间会说明一切的。

N开放SLI是什么后果。。。

没有人怀疑NV不能反超，我们只是在怀疑NV为什么要反超...
因为NV现在是领先位置，为什么是反超而不是扩大优势{mellow:]

剥夺某些人YY的权利，做到完美{biggrin:] {victory:]
