intel and nvidia copicd amd

 - AMD has certainlyenjoyed the high ground for some time now. But is it over? MSI doesn't think so, which is why they'vesponsored today's video, giving us a sneak peek atsomething really exciting. Take a look at... (grunts) This! The GE76 Raider. "Big deal," you might say. Sure, it comes in a cooletched Tiamat edition, but at the end of the day, isn't it just yet anotherIntel/Nvidia laptop? Oh, no, no! This one is different. This laptop support Resizable BAR like AMD does with theirSmart Access Memory. That means that this Intel CPU can access all of thisNvidia GPU's memory at once, just like a Ryzen and Radeon pairing can. Could this be what Intel needsto fight back against AMD? I mean, honestly speaking, I doubt that MSI reallygives a flying (beep). (wings flapping) (gun bangs) (carcass thuds) They're playing it both ways anyway. But this back and forthcan only mean more laptops flying off the shelves to consumers, so I guess that's why they'reraining marketing funds into this fiery showdown. (upbeat music) Just so we're clear, this is not a review. We're only testing this machine today in an on-versus-off configuration. But we should still getto know it a little better so that you guys know what to expect and so MSI doesn't get mad at us. It's got a 17.3" 300-hertz IPS display that should keep our RTX 3080 Max-P busy despite its 1080p resolution. Under the hood, ours has a Core i7-10870H, 32 gigs of DDR4 3200-megahertz RAM, and a 1-terabyte NVMe SSDin one of two M.2 slots. It's got a beefy five-heat pipe cooler for the CPU and GPU that MSIcalls their Cooler Boost 5, and feeding the beast isa 280-watt power brick and a 99.9-watt-hour batterythat's, let's be honest, is essential if you're gonnarun this thing off the wall, especially in the Extreme Performance mode in Dragon Center. In order to toggleResizable BAR on and off we're gonna use an Nvidiadriver that supports it and one that doesn't. Simple. Er, unlike these results. "Shadow of the Tomb Raider"in traditional rendering mode actually got slower withResizable BAR enabled and was identical when weturned on ray-traced shadows. "Wolfenstein: Youngblood" at least picks up a coupleof frames at minimum, but nothing big, and again, has little to boast about when ray tracing is enabled. "F1 2020" is a title that sawsignificant performance uplift with Smart Access Memoryin our Radeon 6800 review, but it loses a few minimum frames with Resizable BAR enabled here, while "Flight Simulator 2020"does gain a frame or two, but just a frame or two. Finally, "CS:GO," a big winner for SmartAccess Memory on AMD, sees, well, a tangibleincrease in minimum frame rates and not much else. For fun we ran 3DMark tosee if a synthetic test might show us more of a difference, but it was within halfa percent either way. When we moved to Blender, we're once again lookingat minimal differences to the point where it's tough to say that there's any realdifference here at all. It's a second faster in CUDA BMW, but then a second slowerin OptiX Classroom. And LuxMark has Resizable BAR losing by about 2% across the board. So does Photoshop, withDaVinci Resolve and Premiere coming within a singlepercentage point of difference. SPECviewperf 2020 againgives us some brutal numbers. Like, we're not far off, but across the board it's on par or slower than the traditional driver, save for CATIA, where itwent up a single point. This all lends a fair bit of credence to AMD's claim that Smart Access Memory is more than simply enablingResizable BAR support and Nvidia's confidence that they could match AMD'sperformance improvements simply haven't materialized here. So does Resizable BAR on Inteland Nvidia close the gap? No-ot yet. You're probably sitting there thinking, "This is kinda a weird sponsoredvideo experience so far, showin' off this crazy,ballin', sexy gaming monstrosity by highlighting howone of its key features makes no difference at all." But wait. There's far more to this story. We reached out to MSI withour results and they said, I'm paraphrasing a little bit here, "Well, what are you,some kind of an idiot? This is an early tech preview. It's only validated underspecific circumstance 'cause the ladies and gents in the lab still have a lotta work to do, ya dunce!" Oh, you guys. (sighs) The good news is that wefound one of those cases where Resizable BAR makes a difference for Intel and Nvidia today: in "Assassin's Creed: Valhalla." Now, because we only have one data point and because we don't havean RDNA 2 mobile GPU yet, we decided to throwtogether a desktop GPU bench with an RX 6800 XT to inform our guesses as to what the performancedifferences might look like between Team Red and TeamBluish-Green in the future. As it turns out, Team Red'sstill got an advantage off of the startingline compared to Nvidia, with roughly double theperformance gain across the board. That's still a significantdeparture, though, from the rest of our results today and it looks like theseimprovements scale proportionally with the amount of additionalpower draw that we observed. This shows that not onlyis there a lot of room for performance to grow from here; for laptop manufacturers like MSI there's also an additional benefit. Being able to increase core utilization and keep the CPU working to feed the GPU means that you could actuallymaintain higher performance than you otherwise might in athermally-constrained chassis. And would you look at that? This actually bears out when we try testing theGE76 Raider in Silent Mode, where the cooling systemis limited for acoustics and the CPU throttles clockspeeds more aggressively. Not only do we get better frame times with Resizable BAR enabled, we're getting them at a smaller increase in power consumption. So in the future, you mightexpect smaller laptops to pack a bigger punchthanks to Resizable BAR. And as for the big ones, well, they'll just get better still. Like our new underweardesigns at LTTStore.com. Oh, those are the oldones. Doesn't matter. The point is, speaking of LTTStore, make sure you get subscribed because, yes, I do know about thecounterfeit LTT merch out there and I'm gonna have a videocoming about it very soon. Back on topic, though. These performance resultsleave us with some questions, like, "What does Resizable BAR even do to get these kinds of results?" and "Why did it take so long to get here?" Resizable BAR is the official PCI-SIG term for what AMD brands Smart Access Memory, which allows a CPU to communicate with all of a PCI Expressdevice's memory at once instead of in smaller 256-meg chunks, which is a big deal becausethat is 1/64 the size of the frame buffer in theRTX 3080 in our GE76 Raider. While AMD only officiallysupports Smart Access Memory on their 500-series chipsets, MSI's been in the news forhaving enabled Resizable BAR not only on 400-series AMD motherboards but on Intel motherboardsas old as their 300-series, which means that owners ofCPUs as old as 8th-gen core can get in on the action too. Now, this has been an optional part of the PCI Expressspecification in some form since at least around 2008, but it's never really been thought of as a desktop technology. It makes sense. I mean, Resizable BAR probably wouldn't have even made much of a difference even a couple of years ago, where on average CPU threadcounts weren't as high and GPUs weren't shipping withtens of gigabytes of memory. But when AMD moved first withtheir Smart Access Memory for their Radeon 6000 series, the industry took notice. As the kids say, "It's free real estate." And AMD's platform tookadvantage of it out of the gate, at least for some games,giving them a head start. This left Intel and Nvidia scrambling to validateand enable a feature that they were always able to turn on but hadn't planned to introduce yet, which is where the GE76 Raider came in. While it might look likejust another gaming laptop... It's got that RGB, right? It's going to be among thefirst with Resizable BAR support for it's 10th-gen Corei7 and RTX 3080 Max-P, once the official drivers land. And as we've seen, RTX 3080's mobileperformance can be very good, so chances are it'll only get better as performance gains like we saw today start showing up in moretitles and getting embiggened. And chances are that I'm gonna tell you a little more about our sponsor MSI here in the sponsorshipportion of the video. The GE76 Raider is theirfirst gaming laptop that's equipped with Wi-Fi 6E, it uses a refined chassis with their customizable light bar, it's got up to an Intel Core i9 processor and RTX 3080 Max-P, it features their DuoWave speakers and woofer, with a full-HD webcam, and, of course, Intel plusNvidia Resizable BAR technology for smoothing out your gaming experience.
