More Details from Lisa Su

The executives at AMD like to break their own NDAs.  Then again, they are the ones typically setting these NDA dates, so it isn’t a big deal.  It is no secret that Kaveri has been in the pipeline for some time.  We knew a lot of the basic details of the product, but there were certainly things that were missing.  Lisu Su went up onstage and shared a few new details with us.

Kaveri will be made up of 4 “Steamroller” cores, which are enhanced versions of the previous Bulldozer/Trinity/Vishera families of products.  Nearly everything in the processor is doubled.  It now has dual decode, more cache, larger TLBs, and a host of other smaller features that all add up to greater single thread performance and better multi-threaded handling and performance.   Integer performance will be improved, and the FPU/MMX/SSE unit now features 2 x 128 bit FMAC units which can “fuse” and support AVX 256.

However, there was no mention of the fabled 6 core Kaveri.  At this time, it is unlikely that particular product will be launched anytime soon.

Retiring the Workhorses

There is an inevitable shift coming.  Honestly, this has been quite obvious for some time, but it has just taken AMD a bit longer to get here than many have expected.  Some years back we saw AMD release their new motto, “The Future is Fusion”.  While many thought it somewhat interesting and trite, it actually foreshadowed the massive shift from monolithic CPU cores to their APUs.  Right now AMD’s APUs are doing “ok” in desktops and are gaining traction in mobile applications.  What most people do not realize is that AMD will be going all APU all the time in the very near future.

We can look over the past few years and see that AMD has been headed in this direction for some time, but they simply have not had all the materials in place to make this dramatic shift.  To get a better understanding of where AMD is heading, how they plan to address multiple markets, and what kind of pressures they are under, we have to look at the two major non-APU markets that AMD is currently hanging onto by a thread.  In some ways, timing has been against AMD, not to mention available process technologies.

Just how does a 5GHz AMD chip perform?

Subject: Processors | July 19, 2013 - 04:13 PM |
Tagged: vishera, TWKR, piledriver, FX-9590, Centurion, amd

As we have been discussing the 220W TDP 5GHz AMD FX-9590 recently it seems a good idea to show what level of performance you can expect from this chip.  Hardware Canucks had a chance to benchmark the performance of this chip using both synthetic benchmarks and some gaming tests.  When they tried to overclock the chip they ran into difficulties with not only heat, as you would expect but they also ran into an issue with power, they maxed out the amount that the board could provide.  Single thread performance is not up to par with SandyBridge-E but in properly designed multi-threaded programs the performance is impressive, though perhaps not for an $800+ chip.

"With the FX-9590, AMD has taken their Piledriver architecture and pushed it to the absolute limit. By running at an astounding 5GHz, this new CPU is the fastest in the FX-series stable."

AMD FX-9000 Series Now Available

Tagged: vishera, TWKR, piledriver, FX-9590, FX-9370, Centurion, amd

If you are looking for an AMD system you can really brag about then the arrival of FX-9590 powered systems at popular retailers like NCIX and system builders like Puget Sound and CyberPower.  Clocked at 5GHz stock it is the highest frequency consumer CPU on the market and as long as you can tame the 220W TDP you might be able to take the chip even higher.  Not every retailer has listed their new systems at the time of posting but right now you can pick up a GENESIS system from Origin that sports a watercooled FX-9590 and depending on your choices the GPU(s) can be watercooled as well.

Velocity Micro also has a system ready for purchase and the Gamer Scorpius 9500 from Cyberpower will be ready in the very near future.  As you are unlikely to see these CPUs for sale in retail boxes this may be your only chance to get a hold of one of these chips.  The prices of the systems will vary widely depending on what components you want inside but keep in mind that you are buying a completely build and thoroughly tested machine with a warranty so don't dismiss these systems without comparing the pricing to what you would pay to build a machine yourself.

More information on AMD's mysterious 5GHz chip

The Tech Report managed to get some more information out of AMD about the new FX-9000 series that the net has been buzzing about.  We now have confirmation that the base clocks for the FX-9590 and FX-9370 are 4.7GHz and 4.4GHz.  They also confirmed that 220W TFP is relatively accurate which will make these the hottest chips on the market.  While you won't see these chips officially for sale outside of specially built systems, there is a chance a few might pop up on eBay and if you are curious how they might perform there is a link in The Tech Report's article to an overclocked Vishera which will give you a rough idea.

"On Tuesday, AMD introduced its new FX-9000-series processors. The company quoted their peak Turbo speeds (5GHz for the FX-9590, 4.7GHz for the FX-9370) and a rough time frame for availability ("this summer"), but it revealed little else. We were left wondering about base clocks, power envelopes, and potential retail availability."

AMD Releases First 5 GHz Processor for Consumers, FX-9590 and FX-9370

Subject: Processors | June 11, 2013 - 11:13 AM |
Tagged: vishera, TWKR, piledriver, FX-9590, FX-9370, Centurion, amd

We have all heard the rumors, but it appears to be true.  We had originally heard about a “Centurion” product which would be for extreme overclockers on the AMD side, running at 5 GHz with a 220 watt TDP.  Now we finally get to see what all the fuss is about.  AMD is releasing two new Vishera based processors that, for the time being, will be limited to system integrators and will be available later this summer.

fx_logo.jpg

The top end product is the FX-9590 which has a top turbo speed of 5 GHz.  This will be a full four module implementation with the 8 MB of L3 cache.  AMD did not give any other details for this particular part.  We do not know what the base clock is, we do not know what the TDP is, and we can only assume that the northbridge/L3 cache will be clocked at the standard 2.2 GHz that we have seen on previous Vishera parts.

The second product is the FX-9370 which is again a four module part that has a top turbo speed of 4.7 GHz.  Remember that the four modules each have two “cores”, so it is still considered an eight core part.  These processors are unlocked, so they can be further overclocked if one so desires.  TDP and other details were again skipped for this particular part.

These parts will be going to system integrators first, and I am not entirely sure that AMD will sell them on the market direct to consumers.  If AMD does in fact sell to consumers (not implied at all in the press release) then they likely will have to bundle it with a very robust cooler.  Probably something along the lines of what we saw with the original FX-8150 LCS bundle.

Consider that the FX-8350 is a 4 GHz base clock product with a max turbo of 4.2 GHz and having a TDP of 125 watts, we probably have to assume that the 220 watt number bandied about is accurate.  A pretty beefy air cooler would be required, or the aforementioned liquid cooling system.  AMD also likely had GLOBALFOUNDRIES change the “mix” when fabricating these parts.  These batches probably feature more leaky transistors that can achieve higher speeds without an extreme amount of voltage.

This is an interesting move by AMD.  Remember those TWKR chips that they released that were designed for LN2 use?  There were a very limited number of those units, and we can imagine that while the FX-9000 series will be in greater numbers they still will not be commonplace on the retail market.  SI’s like Maingear will be introducing systems this summer featuring these chips.  Performance will be good with these solutions, but the tradeoff is of course power consumption and heat production as compared to similarly performing (and stock clocked) Intel i7 3770K and 4770K parts.

AMD is doing their best to address the enthusiast market, but until Kaveri hits the streets we will not see any major upgrades beyond these parts.

Update:

We received some further info about this chip.  The TDP is up in the 220 watt region.  It utilizes Turbo Core 3.0 to help achieve those speeds, so it seems that some of the work that went into Richland has made it into these latest FX processors.  BIOS updates are probably a must.  These chips will only be going to system integrators (SIs) and will be bundled with a liquid cooling system.  We have no idea what the price will be since these will only be sold to SIs.  Systems should be available after July 16.

AMD Releases FX CPU Refreshes

Subject: Processors | April 30, 2013 - 02:04 PM |
Tagged: amd, FX, vishera, bulldozer, FX-6350, FX-4350, FX-6300, FX-4300, 32 nm, SOI, Beloved

 

Today AMD has released two new processors that address the AM3+ market.  The FX-6350 and FX-4350 are two new refreshes of the quad and hex core lineup of processors.  Currently the FX-8350 is still the fastest of the breed, and there is no update for that particular number yet.  This is not necessarily a bad thing, but there are those of us who are still awaiting the arrival of the rumored “Centurion”.

These parts are 125 watt TDP units, which are up from their 95 watt predecessors.  The FX-6350 runs at 3.9 GHz with a 4.2 GHz boost clock.  This is up 300 MHz stock and 100 MHz boost from the previous 95 watt FX-6300.  The FX-4350 runs at 3.9 GHz with a 4.3 GHz boost clock.  This is 100 MHz stock and 300 MHz boost above that of the FX-4300.  What is of greater interest here is that the L3 cache goes from 4 MB on the 4300 to 8 MB on the 4350.  This little fact looks to be the reason why the FX-4350 is now a 125 watt TDP part.

fx_logo.jpg

It has been some two years since AMD started shipping 32 nm PD-SOI/HKMG products to the market, and it certainly seems as though spinning off GLOBALFOUNDRIES has essentially stopped the push to implement new features into a process node throughout the years.  As many may remember, AMD was somewhat famous for injecting new process technology into current nodes to improve performance, yields, and power characteristics in “baby steps” type fashion instead of leaving the node as is and making a huge jump with the next node.  Vishera has been out for some 7 months now and we have not really seen any major improvement in regards to performance and power characteristics.  I am sure that yields and bins have improved, but the bottom line is that this is only a minor refresh and AMD raised TDPs to 125 watts for these particular parts.

The FX-6350 is again a three module part containing six cores.  Each module features 2 MB of L2 cache for a total of 6 MB L2 and the entire chip features 8 MB of L3 cache.  The FX-4350 is a two module chip with four cores.  The modules again feature the same 2 MB of L2 cache for a total of 4 MB active on the chip with the above mentioned 8 MB of L3 cache that is double what the FX-4300 featured.

Perhaps soon we will see updates on FM2 with the Richland series of desktop processors, but for now this refresh is all AMD has at the moment.  These are nice upgrades to the line.  The FX-6350 does cost the same as the FX-6300, but the thinking behind that is that the 6300 is more “energy efficient”.  We have seen in the past that AMD (and Intel for that matter) does put a premium on lower wattage parts in a lineup.  The FX-4350 is $10 more expensive than the 4300.  It looks as though the FX-6350 is in stock at multiple outlets but the 4350 has yet to show up.

These will fit in any modern AM3+ motherboard with the latest BIOS installed.  While not an incredibly exciting release from AMD, it at least shows that they continue to address their primary markets.  AMD is in a very interesting place, and it looks like Rory Read is busy getting the house in order.  Now we just have to see if they can curve back their cost structure enough to make the company more financially stable.  Indications are good so far, but AMD has a long ways to go.  But hey, at least according to AMD the FX series is beloved!

AM3+ Last Gasp?

 

Over the past several years I have reviewed quite a few Asus products.  The ones that typically grab my attention are the ROG based units.  These are usually the most interesting, over the top, and expensive products in their respective fields.  Ryan has reviewed the ROG graphics cards, and they have rarely disappointed.  I have typically taken a look at the Crosshair series of boards that support AMD CPUs.

chvfz_01.jpg

Crosshair usually entails the “best of the best” when it comes to features and power delivery.  My first brush with these boards was the Crosshair IV.  That particular model was only recently taken out of my primary work machine.  It proved itself to be an able performer and lasted for years (even overclocked).  The Crosshair IV Extreme featured the Lucid Hydra chip to allow mutli-GPU performance without going to pure SLI or Crossfire.  The Crosshair V got rid of Lucid and added official SLI support and it incorporated the Supreme FX II X-Fi audio.  All of these boards have some things in common.  They are fast, they overclock well, and they are among the most expensive motherboards ever for the AMD platform.

So what is there left to add?  The Crosshair V is a very able platform for Bulldozer and Piledriver based parts.  AMD is not updating the AM3+ chipsets, so we are left with the same 990FX northbridge and the SB950 southie (both of which are essentially the same as the 890FX/SB850).  It should be a simple refresh, right?  We had Piledriver released a few months ago and there should be some power and BIOS tweaks that can be implemented and then have a rebranded board.  Sounds logical, right?  Well, thankfully for us, Asus did not follow that path.

The Asus Crosshair V Formula Z is a fairly radical redesign of the previous generation of products.  The amount of extra features, design changes, and power characteristics make it a far different creature than the original Crosshair V.  While both share many of the same style features, under the skin this is a very different motherboard.  I am rather curious why Asus did not brand this as the “Crosshair VI”.  Let’s explore, shall we?

The AMD Closed Loop System

Closed loop water cooling is not new, but it certainly is a pretty hot topic now.  Some of the first units out there had some interesting issues (like internal corrosion clogging everything up), but once those teething problems were solved the closed loop systems turned out to be pretty effective and easy to install.  Initially these units had the performance of a top end air cooler, but with a lot lower noise.  The latest generation of liquid cooling systems (LCS) is now further improved and provides performance approaching that of larger, more complex cooling systems.  These products will not replace exotic systems like phase change, but they provide a lot of cooling in a fairly decent sized package.

amd_lcs_01.jpg

Clean lines and graphics give this box a striking look without being tacky.

Last year with the introduction of the AMD FX-8150, AMD decided to create a SKU which not only included the CPU, but also a fairly robust LCS.   This unit is based on an Asetek design which features a double wide cooler/reservoir with the push-me/pull-ya fan combination.  Other manufacturers offer this particular product under a variety of names, but this is simply an AMD FX branded unit with some small cosmetic changes to differentiate it from other units.

AMD will eventually offer this cooler with the new Vishera based FX-8350 CPU (or at least we assume they will), and we wanted to take this combination out for a spin.  In our FX-8350 review we did not hit the overclocking targets that AMD had set.  In most literature that we were provided AMD stated that most FX-8350 parts would be able to hit around 5 GHz with some aggressive cooling.  In our review I was able to get to around 4.6 GHz max and around 4.5 GHz stable with better than average cooling.  The results were not as impressive as we had hoped, but we again did not have a top end cooling solution such as what AMD provides with this particular LCS.

With a brand new LCS in hand, I retested the FX-8350 to see how hard it could be pushed.  I also wanted to see how this particular unit performance in terms of thermal properties.  The results were quite surprising for me, as this is my first real experience with a LCS.
