| AMD does VP9 since Raven Ridge (i.e. since introducing VCN).
| The last chip without VP9 was Vega.
|
| All GPUs coming this year support AV1 decode: Intel gen11, AMD
| Navi 2 and Nvidia RTX 30.

| River, River Forest, Forest Crystal, etc.) [1] why not just keep
| the first noun only and make things simpler. It 's not as if it
| would cause any further confusion at this point.

| _The new Tiger Lake stills falls down against the competition
| when we start discussing raw throughput tests. Intel was keen
| to promote professional workflows with Tiger Lake, or gaming
| workflows such as streaming, particularly at 28 W rather than
| at 15 W. Despite this we can easily see that the 15 W Renoir
| options with eight cores can blow past Tiger Lake in a like-
| for-like scenario in our rendering tests and our scalable
| workloads. The only times Intel scores a win is due to
| accelerator support (AVX-512, DP4a, DL Boost). On top of that,
| Renoir laptops in the market are likely to be in a cheaper
| price bracket than what Intel seems to be targeting._
|
| As I read this, and other reviews/analysis of the Tiger Lake
| node I can see Intel competing with the only tool it has left,
| specialized instruction sets. This continues to create a gap
| between things built for "i86-64" architecture vs "x86-64"
| architectures. What I expect to see from that is Intel touting
| performance advantages in applications that I don't use, and
| never comparing the performance of applications I do use. This
| is a bad place for Intel to be, but it is kind of like sailboat
| racing. In sailboat racing one boat can appear to be ahead of
| its rival to non-sailors, but sailors who know the boat is
| going to have to tack to make the mark recognize it is actually
| behind.
|
| So much of technology is like this, where the choices today
| ripple through the opportunities and choices you will have in
| the future, trying to guess which are the important ones feels
| more like divination than decision making.
|
| This is the second time AMD has made some good decisions that
| have resulted in an advantage. AMD's challenge has been to make
| these sorts of decisions on a regular enough cadence to
| _maintain_ that advantage. If I were a leader in the CPU
| architecture or the manufacturing processes group at AMD I
| would be soooo stressed these days.

| and the bus-bandwith.
|
| tl;dr would be it has about 50% more peak memory bandwith
| than the best Renoir from AMD, which translates to about one
| third when all its cores use that. And can dynamically
| downclock the ring-bus and memory-interface while the cores
| are running at full speed. Which depending on the task can be
| good or bad for the task, but always good for battery. While
| AMD is still on top of that when all cores are used, because
| it has twice many of them.
|
| edit: Some other report mentioned almost instaneous resume,
| and never more than 8 seconds boot time from cold start to
| running desktop.
| ChuckMcM wrote:
| Agreed, however there is a caveat. One of the things we
| discovered at NetApp doing performance analysis of Intel vs
| AMD designs (during the early Opteron days) is that Intel's
| memory bandwidth was constrained by the transaction rate of
| their memory controller. Between pre-fetch traffic and
| pointer jumping workloads (which cause frequent TLB
| invalidation) they were never able to actually reach their
| theoretical bandwidth even with static ram instead of DRAM
| on the memory bus.

| Even with AMD's better performance, OEMs are still shipping their

| designs. I really wanted to hop on the Ryzen train, but USB4
| isn't here yet (despite being able to, no devices have
| Thunderbolt), the displays for Ryzen models are all lackluster,
| and other premium features seem to be missing. With this being
| the case along with the number single-core performance means to
| some and the Xe graphics overhaul, Intel is still in a great spot
| on mobile.

| Given than the Ryzen 4000U (Zen 2) series was the first time

| to be selling. (Of courses, in today's market, almost any
| laptop will sell, there's a ton of demand and not enough
| supply) I'd expect to see higher end designs for the Zen 3
| laptops, especially if AMD is able to get more fab time and
| make enough chips.

| Anyone know why Anand hasn't reviewed the 3080 yet?

| This tweet from their editor-in-chief sheds some light on it:

| $11k-for-a-$1500-graphics-card pricey.
|
| I can definitely see why people want the RTX 3090, it's a

| This is a really important result for Intel, as they might

| Intel managing to eek out some more life out of the one thing
| they still had (and were about to lose): single thread
| performance.
|
| One thing that Intel has done incredibly well these past five
| years is eeking out every damn thing out of Skylake they had
| (IIUC this is still fundamentally an iteration on Skylake,
| albeit the biggest we had since 2015). Their inability to
| improve process and architecture is painful to watch but man
| have they stretched what they already had under this
| competitive pressure.
|
| That power consumption though, oof. Anything that is remotely
| multithreaded suffers immediately, and this will be obliterated
| again by Zen 3 APUs, and likely Apple's A14X. But there's some
| chance now they will still be able to win _some_ benchmarks
| against AMD and Apple into next year, so good for them!
