Lenovo IdeaPad Slim 7 performance preview: The high-end Ryzen laptop we’ve been waiting for - williamsspirly

Like a prize fight weigh-in, the AMD Ryzen 7 4800U in Lenovo's IdeaPad Slim 7 just flexed corresponding nary other ultrabook CPU we've ever seen.

It's well-nig as though the Ryzen 7 4800U snatched the mic from the podium and started hurling insults at Intel's future Tiger Lake CPU. If there was a folding hot seat, we're bound it would been thrown and twisted at Intel's entourage spell the flash bulbs popped.

While we're calm in the action of finishing our testing, the Old results we'ray seeing are gobsmackingly amazing. How impressive? When we started hunting in our spreadsheet for how other laptops performed against the IdeaPad Slim 7's results, we kept scrolling, and scrolling, and scrolling to find something comparable. At that point, any ironware referee worth his or her salt questions whether they're "doing information technology wrong." Did I run the base test? Am I in the wrong row? Do I need to a greater extent coffee?

No. Not at all. The Ryzen 7 4800U in the IdeaPad Slim 7 is just that stupidly fast.

We thought we ran the wrong test, simply nope. The Ryzen 7 4800U in the Lenovo IdeaPad Slim 7 is that fast.

Peep the scores from Maxon's older Cinebench R15 benchmark, which uses all cores to measure a CPU's performance at rendering a 3D image. We're not kidding either. We initially cerebration we ran the wrong test or just listed IT incorrect, but the IdeaPad Slim 7 and the Ryzen 7 4800U is just that bolted in that short, altogether-core performance examine.

As you count at this chart, you should government note the two laptops that are eventide remotely penny-pinching to the IdeaPad's performance aren't even the Lapplander class of notebook. Both the Dell XPS 15 7590 with an 8-nucleus Core i9-9980HK and the new Dell XPS 15 9500 with an 8-core Core i7-107850H CPU are basically 4.5-plus lbs. self-satisfied creation laptops with distinct GPUs and beefy temperature reduction.

Intel's 6-core Comet Lake are next up, only the 4-burden laptops aren't even eating dust compared to the IdeaPad Slim 7, because the traumatize wave from the Ryzen 7 4800U has sucked the dust with it.

Even more interesting is the operation of the Ryzen 7 4700U in the budget-priced Acer Fleet 3. It's also an 8-core CPU, but AMD leaves simultaneous multi-threading (a.k.a. information technology's version of Hyper-Threading) sour. SMT is enabled on the IdeaPad Slim 7 and we're looking at a immense carrying out bump into.

IDG

On a longer workload, the thermals come back into play and the Little 7 comes back to earth. It's tranquil enough to basically make USA what just what Intel's H-class laptops are doing with all that power they own though.

One issue with Cinebench R15 is its short runtime—maybe a minute, if that. Modern laptops are all limited by thermals and a insufficient test doesn't actually tell you how well a laptop can hold a really long task. For that, we run Handbrake and encode a 30GB 1080P file victimization the Android Tablet preset. On an ultrabook, it wont to over an hour to flow from, and was really barely a test to see how well laptops handled heat over a long test. With today's notebooks though, actually running play a CPU encoding task along a 3 lbs. laptop is entirely real.

The result is still pretty amazing, but we do see that the Lenovo IdeaPad Slim 7 doesn't leave its Ryzen siblings in the detritus. It still eats the lunch (and dinner party) of the Intel 10th-gen Comet Lake U and 10th-gen Ice Lake U laptop, but the energy limitations of a thin and light laptop computer are at play. And yes, it's really not that much slower than an 8-core Core i7-10875H in the Dingle XPS 15 9500 either. Phew.

Also CPU performance, AMD's nontextual matter topic too. With the Ryzen 7 4800U, you cause one more graphics core terminated the Ryzen 7 4700U, and you get slightly higher time speeds: 1,750MHz vs. 1,600MHz. The Lenovo IdeaPad Slim 7, however, also sports LPDDR4X RAM clocking as high as 4,267MHz. Most of the Ryzen laptops we've seen feature dual-transport DDR4/3200 retentiveness that's slower, only lower be.

IDG

Dual-channel LPDDR4X/4267 offers about 23 percent more bandwidth over a multiple-channel DDR4/3200 contour.

Artwork public presentation commode typically use all the memory bandwidth it can get so we suspect the IdeaPad Slim 7 gets a boost from both the extra graphics Congress of Racial Equality and the clocks plus the faster LPDDR4X/4267 Random memory.

To see how much more memory bandwidth you'd get, we compared the HP Envy x360 13 with its Ryzen 5 and DDR4/3200 to the Lenovo IdeaPad SlimPad 7 and its LPDDR4X/4267. Don't take this as a repudiation of the HP because we'rhenium really focusing along the main memory subsystem here, and we distrust most another DDR4 laptops would perform the same. When we puzzle a chance, we'll also view the store bandwidth of LPDDR4X/3733 common in Intel Ice Lake laptops use. Just to note: Intel's Tiger Lake will support LPDDR5X at even higher time speeds.

Ryzen desktop CPUs typically welfare from increased store pin grass, but we bear the integrated Radeon graphics in Mobile Ryzen to see an even more square boost. Let's look at how to the Ryzen 7 4800U does with its quicker LPDD4X RAM. We'll use the logical 3DMark Sky Diver as a way to caliber performance.

IDG

The additional CU, higher clocks and quicker main retentiveness gives the Ryzen 7 4800U in the IdeaPad Slim 7 a really healthy increase in graphics performance.

The resultant is a precise healthy bump in performance all over the septet Radeon cores in the Ryzen 7 4700U, simply some of that is the raised number of graphics cores, the increased clock speeds, and also the increase in CPU screw thread count, as the score preceding is the boilersuit solvent. Delving into just the graphics score for 3DMark Sky Diver, IT gets a trifle closer. Lenovo's IdeaPad Slim 7 and its Ryzen 7 4800U gave us a score of 13,083; the Ryzen 5 4500U in the H.P. Envy x360 13 got 9,547; and the Acer Swift 3 and its Ryzen 7 4700U finished with 10,888.

And no: There is no Thunderbolt 3

The notification in the bottom-right recession of this screenshot appears when you male plug a Thunderbolt twist into the Lenovo IdeaPad Slim 7.

Despite approximately precocious reports that the IdeaPad Slim down 7 has the Sangraal of features in an AMD laptop—Thunderbolt 3—it doesn't. Later meter reading those reports, we got giddy with our Thunderbolt 3 accessories, only to closing up with the same Charlie Brown University football game we've seen along Ryzen 4000 laptops for the last cinque months.

What this means

So what does this every last matter? Intimately, the main take off is that the Ryzen 7 4800U has at length arrived just in time for the primary fight.

IDG

Tiger Lake is likely to cleanable Ryzen 4000's clock on solitary-threaded carrying out and that power retributory substance more.

When Intel unwraps its 11th-gen "Tiger Lake" CPUs next week, we'll witness an epic fight for the soul of cadaverous and light laptops unlike any we birth ever seen before. Our earlier anticipation that Tiger Lake will lose against Ryzen 4000 in multi-threaded tasks girdle the same. Well, rather. Afterwards seeing the Ryzen 7 4800U's results, we actually think it'll be a total blowout in multi-threaded performance now. Graphics, however, might just be closer than we expected. And one area Tiger Lake is likely to win big is single-threaded performance, which is really in all probability more important for most of what it is through in a small laptop.

Stay keyed for our full follow-up of the Lenovo IdeaPad Slim 7, and for more information about Intel's imminent Tiger Lake counter.
